Genomic and physiological characterization of Escherichia coli evolving in long-term batch culture

Tuesday, March 10, 12 PM, AHF 153 (Torrey Webb Room)

Abstract: In most natural environments, bacteria spend much of their time under conditions of starvation and stress. Long-term batch cultures are an excellent laboratory system to study adaptation during nutrient stress because cells are incubated for relatively long periods of time, months to years, without the addition of nutrients. During long-term batch culture cells adapt to acquire energy from cellular detritus creating a complex and dynamic environment for mutants of increased relative fitness to exploit. To characterize the population dynamics and identify beneficial alleles, we analyzed the genomes of 1117 clones isolated from a single long-term batch culture inoculated with a single clone and incubated for 1200 days. A total of 679 mutations were identified including single nucleotide polymorphisms, indels, movement of mobile genetic elements, large deletions up to 64kbp and amplifications up to ~500kbp. During the 3.3-year incubation, two main lineages diverge and continuously evolve. There is evidence of at least two instances of a fixed mutation reverting back to the wild type allele, suggesting beneficial mutations may later become maladaptive. Most of the mutated genes encode proteins involved in metabolism, transport, or transcriptional regulation. Clones from the two lineages are physiologically distinct based on outgrowth in fresh medium and competition against the parental strain. Similar population dynamics and mutated genes were detected in three parallel populations sequenced through day 60 providing evidence for positive selection. These data provide new insight into the population structure and mutations that may be beneficial during periods of starvation in evolving bacterial communities.

Understanding biodiversity, one cell at a time

Thursday, February 6, 12 PM, AHF 153 (Torrey Webb Room)

Abstract: I study novelty. Specifically, I am interested in understanding the factors that drive the origin and diversification of novel cell types. More than just taxon-specific oddities, novel cell types can promote niche specialization and facilitate speciation events; thus, studying novelty is critical for understanding the evolution of biodiversity. One of my favorite projects focuses on understanding the mechanisms driving morphological and functional specialization of cnidocytes (stinging cells) across cnidarians (corals, jellyfish, and their kin). Using a combination of observational and functional techniques, I have constructed a cnidocyte gene regulatory network that I use to test hypotheses about the evolutionary origin of this truly bizarre lineage of cells. Surprisingly, the fate of this novel cell lineage seems to have been acquired through recycling and reorganization of an old gene regulatory network, rather that the origin of a novel regulation strategy.

From the Mountains to the Sea: Comparative Genomics of Mechanisms Underlying the Physiological Response to Low Oxygen

Tuesday, January 28, 12 PM, AHF 153 (Torrey Webb Room)

Abstract: Environmental variables can exert a considerable selective pressure across the entire organism – from their genome to their physiology. Organisms living in extreme environmental conditions provide excellent systems to investigate numerous basic questions about the limits of an organism's ability to adapt, to understanding the inherent repeatability of molecular adaptation, and thus the origins of biodiversity, by examining both phenotypic and genotypic novelty. My work uses both integrative and comparative approaches to understand the mechanisms underpinning the response to such environmental variables, with a focus on oxygen availability (i.e. hypoxia). This talk will journey through my previous work on high-altitude adaptation in Andean duck species, to my current work on hypoxia in copepods (and other crustaceans), and conclude with how my discoveries opened up numerous exciting avenues for future work in aquatic invertebrates.

Molecular and cellular bases of cnidarian-dinoflagellate symbiosis and its breakdown

Tuesday, January 21, 12 PM, AHF 153 (Torrey Webb Room)

Abstract: The symbiosis between corals and dinoflagellate algae is essential to the energetic requirements of coral-reef ecosystems. However, coral reefs are in danger due to elevated ocean temperatures and other stresses that lead to the breakdown of this symbiosis and coral "bleaching". Despite the importance of coral reefs, the molecular basis of how corals maintain a healthy symbiosis and avoid bleaching is poorly understood, in part because of the lack of a tractable genetic model system. The small anemone Aiptasia is symbiotic with algal strains like those in reef-building corals but has many experimental advantages, making it an attractive laboratory model for cnidarian symbiosis.  To explore the transcriptional basis of heat-induced bleaching, we used RNAseq to identify genes that are differentially expressed during a time course of heat stress of symbiotic and aposymbiotic Aiptasia strains. We observed a strong upregulation of hundreds of genes at times long before bleaching begins in symbiotic anemones. The putative promoters of these early stress-response genes are enriched for binding sites for the NFB and HSF1 transcription factors, suggesting that many of these genes share core transcriptional control. The overall expression patterns were similar between the symbiotic and aposymbiotic anemones, indicating that many of the expression changes are not specific to the presence of the algae. Nonetheless, reducing HSF1 activity with a pharmacological inhibitor resulted in more severe bleaching, suggesting that this symbiont-independent stress response is protective against bleaching.
           
Genetic tools are needed to allow rigorous functional testing of the roles of candidate genes in symbiosis and bleaching. Recently, we have developed methods for knocking down and overexpressing genes of interest in Aiptasia. Meanwhile, we have successfully used the CRISPR/Cas9 technology to create genetic changes in embryos of the coral Acropora millepora. We used this technology to knock out HSF1 and demonstrated its role in coral heat tolerance. Through the establishment of both gain-of-function and loss-of-function methods in both Aiptasia and corals, it will be possible to exploit the year-round spawning of Aiptasia to perform initial tests of gene function in cnidarian-algal symbiosis and then further test the discoveries made using similar technologies in corals.

Trials, tribulations, and transcriptomes: Understanding microbial ecosystem processes along the western Antarctic Peninsula

Tuesday, Nov. 5, 12 PM, AHF 153 (Torrey Webb Room)

Abstract: The western Antarctic Peninsula (WAP) is a dynamic marine environment defined by contrasting onshore and offshore water masses, rapidly shifting sea ice conditions, and strong season cycles of light and temperature.  The region is well known for its charismatic megafauna, but the charisma of its marine microbes is just beginning to emerge.  I’ll describe some of our efforts over the last several years to understand the dynamics of marine microbial communities along the WAP, culminating in our ongoing effort to use metatranscriptomics to understand the carbon and energy transfers associated with the winter-spring seasonal transition.  This transitional period is dominated by lipid metabolisms among a surprisingly diverse group of marine phytoplankton.  Given the variability in timing of the annual sea ice retreat, and the importance of lipid-rich phytoplankton in regional foodwebs, we anticipate implications for metabolic energy budgets across trophic levels.

Nitrification as a window on the mesopelagic

Tuesday, October 7
12 PM
AHF 153 (Torrey Webb Room)

Abstract: The mesopelagic ocean--often called the “twilight zone”--is a critical area for the microbial processing of sinking organic matter. Our lab studies some of the most abundant members of the mesopelagic microbial community, the ammonia-oxidizing archaea and nitrite-oxidizing bacteria. Together, these organisms carry out the biogeochemical process of nitrification and are responsible for producing the vast deep ocean nitrate reservoir. They also play an underappreciated role in carbon and trace metal cycling. My talk will describe combining laboratory cultures with field rate measurements to understand the critical role of nitrifiers in the intertwined geochemical cycles of carbon, nitrogen, and trace metals in the dark ocean.

Coral Reefs in a Changing Climate: Challenges and Reasons for Hope

Tuesday, October 1
12 PM
AHF 153 (Torrey Webb Room)

Abstract: Already under severe pressure from a number of stressors, including overfishing and pollution, coral reefs are also among the most vulnerable ecosystems to climate change and ocean acidification: We have lost an estimated 50% of the world's coral reefs over the last several decades and are projected to lose more than 90% by 2050. While acute disturbances such as temperature-induced coral bleaching are largely responsible for accelerated reef decline in recent years, chronic disturbances like ocean acidification erode a reef’s capacity to recover by slowing growth and reproduction. In this talk, I will give an overview to the challenges that reefs are currently facing, focusing on the impacts of changing seawater chemistry on various aspects of coral reef biology, ecology, and biogeochemistry.  We will also explore some of the novel and exciting ideas that are emerging to address the coral reef crisis. We'll highlight strengths and limitations of current approaches and discuss next steps towards saving these valuable ecosystems.

Abstract: Feedbacks between biological and geological processes drove the co-evolution of life and the environment. Yet, little is known of the nature of these feedbacks and the time scales over which they occurred. Here we describe a series of geobiological feedbacks that have played out over the past ~1.1 to 0.8 Ga and that shaped the co-evolution of thermoacidophiles and their acidic hot spring habitats. Future experimentation will evaluate kinetic controls on the acid-generating reactions and the physiological adaptations that allowed microbes to exploit these reactions to fuel their metabolisms.

The impact of organic compounds on the cycling of trace metals in the ocean

Tuesday, September 10, 2019
12 PM
AHF 153 (Torrey Webb Room)

Abstract: Trace metals such as iron are essential nutrients for phytoplankton and bacteria, impacting primary productivity in many regions of the ocean. Our understanding of the iron cycle has improved dramatically since the dawn of the international GEOTRACES program, with the chemical speciation of iron emerging as a key control on the oceanic inventory of iron. The speciation of dissolved iron in seawater is dominated by complexation to a diverse pool of organic compounds which impact the bioavailability and reactivity of this scarce nutrient, yet the identity of these compounds are largely unknown. In this talk I will discuss how we determine the identity of these compounds in seawater with novel analytical tools, and why these organic ligands are important for trace metal cycling.

Eddy-driven variability in nitrification in the subtropical North Pacific Ocean

Tuesday, September 3
12 PM
AHF 153 (Torrey Webb Room)

Abstract: Nitrification is a key step in the marine nitrogen cycle, controlling oxidation of reduced nitrogen in the ocean. Mesoscale eddies, which vertically perturb isopycnal surfaces within the main pycnocline, are thought to play important roles in upper ocean biogeochemical processes; however, potential impacts of eddies on microbial nitrogen cycling in the dimly-lit mesopelagic waters remains largely unknown. In this talk I will summarize on-going work examining how eddies influence the export of particulate nitrogen (PN), rates of nitrification, and the abundances and spatial distributions of nitrifying Archaea (using the ammonia-monooxygenase gene [amoA] as a biomarker) in the oligotrophic waters of the North Pacific Ocean. Eddies influence upper ocean nutrient pools and fluxes, shape the distributions of nitrifying microorganisms and rates of nitrification in the mesopelagic waters. These results suggest that eddy-mediated changes to the upper ocean can have important roles in modifying nitrogen transformation in the interior waters of the ocean.

Adaptive potential and limits in Caribbean acroporid corals

Tuesday, August 27
12 PM
AHF 153 (Torrey Webb Room)

Abstract: Reef-building corals are currently threatened by rapid changes in local and global stressors, and hybridization offers a potential shortcut for rapid adaptation and evolutionary rescue in these species. The sympatric corals Acropora palmata and A. cervicornis form the hybrid, A. prolifera, whose abundance has continued to increase while the parental species decline. Previous work indicates that weakened prezygotic isolation mechanisms in A. cervicornis but not A. palmata could allow for continuous unidirectional gene flow between the two species. Furthermore, asymmetric introgression from A. palmata to A. cervicornis has been recorded in three nuclear loci. In contrast, we found evidence for bidirectional introgession across three hybrid zones, although the frequency of hybrids and backcrosses differs across the range. Genome assemblies of A. palmataand A. cervicornis were compared to other corals to identify orthologs uniquely shared by the Caribbean acroporids. Genomic sequence data from the two parental species and their hybrids was used to further characterize the patterns of genomic synteny, divergence and introgression across hybrid zones. Combined, these approaches elucidate genomic hotspots of introgression and parallel evolution with implications for how hybridization may shape adaptation in these important foundation species across the Caribbean and North-West Atlantic.

The dynamic regulation of DMSP production by marine phytoplankton

Wednesday, May 8, 2019
10 AM
AHF 153 (Torrey Webb Room)

Abstract: Dimethylsulfoniopropionate (DMSP) is a labile sulfur and carbon metabolite that significantly contributes to both the cycling of marine dissolved organic carbon and the balance of Earth’s albedo. DMSP is produced by the majority of eukaryotic marine phytoplankton and by many prokaryotes, but despite decades of research, the cellular mechanism and environmental drivers of DMSP production remain unknown. My thesis confirms that the cellular mechanism of DMSP is differentiated by the cellular concentrations of DMSP in different producers, where high DMSP producers (e.g. dinoflagellates and haptophytes) constitutively produce DMSP and low DMSP producers (e.g. cyanobacteria and diatoms) actively regulate DMSP production in response to environmental stress. However, with natural community experiments and global model predictions, my thesis demonstrates that variability of in situ DMSP production is driven by the biomass of high producers. My thesis highlights the potential for predicting in situ DMSP concentrations with a high DMSP producer marker gene and demonstrates the importance of accurately capturing the sub-dominant community for prediction of DMSP, or other similar metabolites produced by a small fraction of the marine microbial community.

Thermal Acclimation and Adaptation of Key Phytoplankton Groups and Interactions with Other Global Change Variables

Wednesday, May 1, 2019
11 AM
AHF 153 (Torrey Webb Room)

Abstract: Marine phytoplankton play critical roles in global primary productivity, carbon export and biogeochemistry. The relationships between environmental forcing and key phytoplankton groups in marine ecosystems need more attention, especially under global change scenarios. Among many other environmental changes, phytoplankton communities in the euphotic zone are anticipated to be most sensitive to concurrent ocean acidification, warming, more thermal variability and reduced nutrient supplies.

Marine diatoms play critical roles in global primary productivity, carbon export and the food web. Marine diazotrophic cyanobacteria are equally important as a source of new nitrogen through nitrogen fixation. In order to better understand the possible responses of marine diatoms and diazotrophs to a changing ocean environment, my studies focused on the synergistic effects of multiple climate change variables on an important diatom, as well as the responses of two keystone diazotrophs to thermal variability and to long-term selection by warming.

In my first chapter, the physiological responses of the widespread centric diatom Coscinodiscus sp. to interactions between three climate-change variables (elevated CO2, warming, and nitrate availability) were investigated to better understand the interactions of multiple global changes on large, carbon-exporting diatoms. The second one examined how short-term thermal variability affects the growth and physiology of the diazotrophic cyanobacterium Trichodesmium erythraeum GBRTRLI101, as well as the interaction between temperature variation and phosphate availability. The third chapter tested the physiological responses and compared and contrasted acclimation and  adaptation of Trichodesmium erythraeum IMS101 and Crocosphaera WH0005 under long-term experimental selection at different temperatures, exploring possible ecological and biogeochemical implications of ways that these two representative diazotrophic cyanobacteria may cope with future warmer conditions.

Long-term dynamics of free-living and particle-associated prokaryotic communities at the San Pedro Ocean Time-series

Abstract: The free-living and particle-associated marine prokaryotes have been proved to differ in their diversity and composition, but drivers of their long-term dynamics are poorly understood. We thus investigated surface to bottom dynamics of free-living (0.2-1.2 µm) and particle-associated (1.2-80 µm) prokaryotes at the San Pedro Ocean Time Series (SPOT) during 2000-2018 by using ssu rRNA tag sequencing. We assessed factors influencing the temporal variation of community composition by canonical correspondence analysis (CCA), and community turnover by the β-nearest taxon index (βNTI), a measure designed to assess the extent of stochastic vs. deterministic drivers. The results showed free-living and particle-associated prokaryotic communities both have strong seasonality at the surface and the deep chlorophyll maximum (DCM), though seasonal variation decreased in warm years, notably after 2012. Moreover, the free-living fraction exhibited a relatively stable dynamic without decreasing in average similarity over time, whereas the particle-associated fraction was undergoing directional change.

Mechanisms of food and temperature impacts on growth in the ocean

Abstract: Variations in sources of energy and temperature have major impacts on the survival and growth of organisms. For marine larval forms, the degree to which food availability can alter physiological tolerances to thermal stress remains unknown. In this presentation, the physiological mechanisms of growth that are impacted by food quantity and temperature will be analyzed, in addition to food-temperature interactions. The goal of these studies is to understand resilience potential to future scenarios of ocean change.

Using 𝞪, 𝞫, and 𝞯 diversity in describing the health of stream-based benthic macroinvertebrate communities

Abstract: Ecological monitoring of streams has frequently focused on measures describing the taxonomic, and sometimes functional, α diversity of benthic macroinvertebrates (BMIs) within a single sampled community. However, as many ecological processes effectively link BMI stream communities there is a need to describe groups of communities using measures of regional diversity. Here we demonstrate a role for incorporating both a traditional pairwise measure of community turnover, β diversity, in assessing community health as well as ζ diversity, a more generalized framework for describing similarity between multiple communities. Using 4395 samples of BMI stream communities in California, we constructed a model using measures of α, β, and ζ diversity which could account for most of the among-watershed variation in the mean health of communities, as described by the California Streams Condition Index (CSCI).

Extreme Alliances: Relationships between deep-sea animals and bacteria

Tuesday, April 16, 2019
12 PM
AHF 153 (Torrey Webb Room)

Abstract: Forty years ago, scientists discovered invertebrates at the bottom of the ocean that forever changed how we view life on this planet. Abundant, thriving communities were not expected in the deep-sea, due to the very low levels of organic carbon that arrive at these depths from above. Certain worms, bivalves, and others, however, have forged relationships with bacteria, in order to harness inorganic sources of energy, typically foreign to animals. Symbiosis is the best of both worlds -- Morphological diversity of animals, and the Physiological diversity of bacteria. This seminar will highlight examples of deep-sea animal-bacterial symbioses from a variety of animal groups - some recently discovered, revealing surprising new relationships between animals and bacteria, and some among the oldest known.

Efforts in enrichment of novel photoautotroph identified through metagenomics

Abstract: Aerobic anoxygenic phototrophs are ubiquitous throughout the global ocean, making up to 11% of the community in some locations. Traditionally aerobic anoxygenic phototrophs have been associated with photoheterotrophy while anaerobic anoxygenic phototrophs were associated with facultative photoautotrophy. Using draft genomes generated from the Tara Oceans metagenomic dataset, 11 draft genomes were identified that lacked key genes for survival in suboxic environments and possessed key genes with the potential for anoxygenic phototrophy via Type-II photochemical reaction centers, carbon fixation via the Calvin-Benson-Bassham cycle, and lithotrophic energy utilization via the oxidation of sulfite and/or thiosulfate. To further study this group and characterize its carbon fixation capability and metabolism there is a need to enrich or isolate the organism. Here we have used comparative genomics to predict the potential metabolism and designed a low nutrient autotrophic medium to enrich for this group using sea water collected at the surface from the San Pedro Ocean Time series (SPOT).

Thermal Diversity in a Coastal Marine Synechoccus Population Selected Under Low- and High Temperatures

Abstract: Synechococcus is a photoautroph found from the equator to near polar waters and contributes together with other picocyanobacteria as much as 25% of net primary productivity in the ocean. The effect of temperature on intraspecific Synechococcus diversity and evolution is well documented; however, it is usually expressed as changing the distribution and relative abundance of distinct clades. To probe for diverse phenotypes, we enriched for photoautotrophs from water collected at the Narragansett Bay Time-series and grown at unseasonably low (18° C) and high (30°) temperatures. From these enrichments, we isolated multiple Synechococcus sp. and quantified their thermal niche by generating thermal performance curves for each, which revealed distinct thermotypes characterized by different maximum temperature limits and optimal temperatures. To understand the genotypic diversity underlying observed phenotypic diversity, we sequenced the genomes of 8 strains, and we found evidence that suggests that variation in genes underlying accessory photosynthetic pigments appears to be related to thermal phenotype in our Synechococcus strains.

Challenges with linking genes to organismal function

Abstract: The leading edge of biological discovery is enabled by a limited number of “model” organisms, with sophisticated resources for the study of genes and their function. Studies of most organisms, however, lack such resources, in particular for the study of functional genomics. The increasing availability of completed genomes and the use of biotechnology in “non-model” organisms offer new opportunities to bridge gaps in understanding biological function, from genes to the whole-organism. I will present some recent steps taken to understand the function of an expanded set of orthologous genes that have been identified in developmental stages of marine invertebrates. These studies have implications for understanding the molecular biological basis of nutrient uptake, with predicting links to whole-organism growth rates.

Investigating algal-bacterial interactions with stable isotope probing and NanoSIMS

Tuesday, March 26
12 PM
AHF 153 (Torrey Webb Room)

Abstract: One of my primary research interests is how interactions between heterotrophic bacteria and eukaryotic algae control elemental cycling and primary productivity. This has implications in natural ecosystems (lakes and oceans) as well as engineered phototrophic systems such as photobioreactors and outdoor algal ponds. I use combinations of laboratory and field studies and methods such as 16S rRNA microbial community characterization, genomics, proteomics, and stable isotope probing combined with NanoSIMS to investigate these interactions. I will first describe how NanoSIMS-based approaches allow an unprecedented ability to quantify microbial anabolic activities at the single-species and single cell level in order to test hypotheses about microbial identity and function. I will then present several past and ongoing studies where this approach has been used to investigate microbial processing of algal-derived organic matter, climate impacts on transfer between algae and bacteria, and bacterial impacts on cell-specific algal growth.
