Grand Computational Challenges in the Metagenomics Era | Computational Biology Colloquium

Abstract:
Microorganisms constitute the most abundant life forms on Earth’s biosphere, and play integral and unique roles in ecosystem functioning, such as biogeochemical cycling of carbon (C), nitrogen (N), sulfur (S), phosphorous (P) and various metals. Understanding the functional diversity, composition, structure, and interactions of microbial communities across different spatial and temporal scales is a critical issue in microbial community ecology. However, analyzing microbial community structure and linking community structure to functions are very difficult. Metagenomics and associated genomics technologies such as high throughput sequencing and functional gene arrays have been demonstrated to be powerful tools for understanding microbial community composition, structure, function, and dynamics and linking microbial communities with environmental factors and ecosystem functioning. With recent advance in metganomics technologies, massive experimental data can be produced, but one of the greatest difficulties is how to handle, analyze and synthesize such massive metagenomics data. In this talk, I will first briefly highlight the current status and most recent development of metagenomics technologies. Then I will describe some great challenges in handling sequencing-based soil metagenomics data. Also, I will describe mathematical prediction of random sampling problems, which results in artifacts in overestimating microbial community diversity across different samples. In addition, I will introduce a new random matrix theory-based mathematical framework to describe ecological network interactions based on metagenomics data, their challenges, and future directions.

Oxygen & the Ecology of Upwelling Margins In a Changing Ocean - An MEB Thursday Noon Seminar

OXYGEN AND THE ECOLOGY OF UPWELLING MARGINS IN A CHANGING OCEAN
PROFESSOR LISA LEVIN
UC San Diego

Sept. 25 @ 12 PM
AHF Torrey Webb Room

Persistent hypoxia (low oxygen) alters both structural and functional aspects of benthic communities, with major consequences for ecosystems services at shallow and bathyal depths. Continental margins subject to upwelling exhibit strong gradients in oxygen, CO2 and temperature, and can serve as ideal natural laboratories for the study of environmental stressors.  Several decades of study of open ocean oxygen minimum zones (OMZs) reveal massive influence of oxygen on benthic abundance, biomass, body size, species composition, species distributions, lifestyles and biodiversity. Differing low-oxygen sensitivities exist among taxa as a function of phylogeny, body size and exposure history, leading to very different oxygen thresholds and responses. Functional consequences of the structural changes include shifts in trophic pathways and efficiency, enhanced roles for chemosynthesis, altered predator and prey encounter dynamics, changing pathways of carbon processing and burial, reduced ecosystem resilience, connectivity and a host of other emergent properties.

As a result of rising CO2 in the atmosphere, upwelling margins are experiencing increased coastal hypoxia and hypercapnia (high CO2).  The strong natural variability of O2 and CO2 on multiple time scales poses a challenge for understanding population and ecosystem responses to OMZ expansion. Approaches for resolving the effects of declining oxygen and pH on margin ecosystems and their services include the use of natural environmental gradients, laboratory manipulations, geochemical proxies and time series data. Scientists today are faced with a need to integrate the influence of natural variability, climate-driven change and direct human activities in management of continental margin ecosystems and resources. The US West coast is increasingly becoming a testbed for ways to address this challenge.

ChIP-seq: unleashing its full potential through data integration - Computational Biology Colloquium

Computational Biology Colloquium

“ChIP-seq: unleashing its full potential through data integration”

RRI 101
Hosts:  Ting Chen

Abstract:
One major goal of functional genomics is to comprehensively characterize the regulatory circuitry behind coordinated spatial and temporal gene activities. With the ability to map genome-wide transcription factor binding sites and histone modifications, ChIP-seq has quickly become an indispensable tool for studying gene regulation. Despite its unprecedented power, a number of challenges must be overcome before one can take full advantage of this high-throughput technology. First, ChIP-seq is increasingly used for analyzing dynamic changes of regulatory circuitry across different biological contexts (i.e., different cell types, time points, etc.). The conventional methods for analyzing data for one protein in one cell type cannot meet the emerging needs for characterizing quantitative and synergistic changes of DNA binding of multiple proteins between different conditions. New methods are required for dealing with the exponentially growing number of multi-protein combinatorial patterns, and for evaluating the statistical significance given the background biological and technical variation. Second, ChIP-seq is high-throughput with respect to analyzing the whole genome, but low-throughput with respect to analyzing gene regulation in a large number of biological contexts. New strategies need to be developed to better utilize ChIP-seq data originally collected from one biological system to gain insight into gene regulation in other biological systems or diseases. Third, ChIP-seq data also contain information on allele-specific binding (ASB). However, applying ChIP-seq to study ASB often suffers from low statistical power due to the limited number of reads mapped to heterozygote SNPs. In this talk, I will demonstrate that the problems above may be approached computationally by developing new statistical methods for jointly analyzing multiple ChIP-seq datasets and methods for integrating ChIP-seq data with enormous amounts of gene expression data in Gene Expression Omnibus (GEO).

From Correlative to 3D – Recent Advances in Bio Scanning Electron Microscopy
September 25,12.30
Irani Hall  RRI 101

Kirk J. Czymmek, Ph.D.
Director of North American Applications & Labs
Carl Zeiss Microscopy, LLC

Biological structures, such as organelles, bacteria, somatic cell layers, tissues and model organisms are inherently three-dimensional (3D) and technologies that aid visualization and analysis of 3D biological samples is growing rapidly. Specifically, recent developments in Bio Scanning Electron Microscopy allow high-resolution imaging of samples embedded in resin, then physically sliced and the resulting sections collected in a serial ribbon on tape, glass slide or slotted grid. Each approach has unique benefits and allows access to antibody and other affinity probes for interrogation of specific molecules.  Alternatively, 3D tomograms of entire sliced volumes can be automated with serial block face imaging, where an ultramicrotome is either integrated directly into the electron microscope chamber or a focused ion beam (FIB) is used to mill away the specimen. Block face images have significantly lower distortions associated with material removal than the compression seen in thin sections, thus final 3D EM reconstructions from this approach align closely with the 3D LM volume image. Furthermore, a far greater understanding of the structure-function relationship in cells and tissues is now achievable via high resolution correlation of chemical markers and structural components in both 2D and 3D dimension. This presentation will focus on contemporary methods and probes, methods and workflow for array tomography, serial block face imaging and correlative light and electron microscopy (CLEM) and demonstrate with practical examples how these tools can provide  powerful and novel  insights into biological problems.

Abstract: The Anthropocene is characterized as an epoch when human influence has begun to fundamentally alter many aspects of the Earth system, and many of the planet¹s biomes. Here I review and synthesize our understanding of Anthropocene change in tropical forests, in the context of the long-term environmental history of humanity in the tropics from the Pleistocene to the present. I explore possible reactions and responses to change in the tropics. Key facets of Anthropocene change in tropical include deforestation, timber and wood extraction, the loss of fauna that maintain critical ecological connections, the spread of fire, landscape fragmentation and the spread of second-growth forests, invasion and pathogen spread, and increasing CO2 and climate change. The patterns of change are spatially heterogeneous, often have strong interactions among them, can have both large-scale and remote effects and play out through ecological cascades over long time scales. As a consequence, most tropical forests are on a trajectory to becoming altered ecosystems, and many are becoming novel ecosystems. I explore strategies for shaping the transition of tropical forests through the early Anthropocene, as well as highlight opportunities and challenges for the tropical forest science and conservation community.

SPECIAL SEMINAR

Microbialite genetic diversity and N cycling
Luisa I Falcón
Bacterial Ecology Lab., Institute of Ecology, UNAM

Microbialites have played an important role in the early history of life on Earth with fossilized forms representing the oldest evidence of life on our planet dating back to 3500 Ma. Extant microbialites have been suggested to be highly productive and diverse communities with an evident role in the cycling of major elements, and in contributing to carbonate precipitation. We have analyzed microbial genetic diversity of microbialites living in different types of environments throughout Mexico, including desert ponds, coastal lagoons and crater-lakes. Microbialite communities are very diverse (H = 6–7) and show geographic variation in composition, as well as an environmental effect related to pH and conductivity, which together explain 33% of the genetic variation. N cycle pathways including N2 fixation, nitrification, denitrification and anammox are evident in the potential community, but only N2 fixation by heterocyst-forming Cyanobacteria within Nostocales are actively transcribed. Our studies suggest that N limitation in the environment strongly favors autotrophy and diazotrophy and restricts remineralization pathways via denitrification and anammox. Cyanobacteria that form heterocysts and are actively transcribing for N2 fixation, are fundamental players in microbialites since they are responsible for providing reduced N –amides, C in lipids and carbohydrates, and host in their external cell membranes the main sites of carbonate mineral precipitation.
