CSP Annual Call

CSP FY2021 (Status: CLOSED)

The DOE JGI’s Community Science Program (CSP) is now accepting Letters of Intent for large-scale genomic science projects that address the following areas of emphasis and exploit the diversity of DOE JGI capabilities.

I.  Genes to Function

Today’s ability to generate sequence data far outpaces assigning validated function to genes. Gene annotation tools are becoming more sophisticated but still rely on the provenance of previously generated information for comparative analyses. Building a broader understanding of gene function in plants and microorganisms will enable the development of new biosynthetic routes for biofuels, biomaterials and bioproducts. Projects of interest may include:

• Annotation of gene function using advanced computational analyses, functional genomics, DNA synthesis and/or metabolomics
• Generation of genome-wide CRISPR gRNA libraries that enable gene function characterization
• Coupling genetic information with protein structure and function by combining sequence-based methods with structural or imaging data
• Characterization of secondary metabolite biosynthetic gene clusters and their products that spans genome mining, expression and/or determining produced metabolites using metabolomic approaches

II. Plant Functional Genomics and Microbiomes

The DOE JGI has produced several “flagship plant genomes” including Brachypodium, Chlamydomonas, Physcomitrella, miscanthus, poplar, Setaria, soybean, sorghum, and switchgrass/Panicum. These taxa are of special interest as potential biofuel feedstocks or as comparators that provide insight into feedstock evolution and phenotype, and projects that directly relate to these genomes are encouraged. For all plant proposals, priority will be given to multi-organism proposals that 1) seek to compare among plants and/or analyze plant-microbiome interactions, and/or 2) are of a large, collaborative nature with multiple participating investigators. Projects of interest may fall into one of the following four categories:

a) Comparative transcriptomes and functional assays– The DOE JGI is currently sequencing flagship plant transcriptomes under a variety of experimental conditions with an emphasis on plant stress response. New proposals are encouraged that expand experimental conditions or expand the range of plants to be studied and extend functional studies beyond straightforward transcriptomics (e.g. metabolomics). This can include proposals for genome-wide annotation of gene regulatory sequences to understand gene function across evolutionary time in areas such as: abiotic stress, development patterning, or signaling systems (See core capabilities below for available assays).

b) Large-scale germplasm resequencing – We invite germplasm resequencing projects aimed at 1) understanding natural population structure of a genus/species, 2) creating a foundation for large scale GWAS projects for gene discovery, or 3) developing pan and core genomes to determine a complete picture of gene content within a genus/species.

c) High quality de novo genomes – We invite proposals for whole genome sequencing of species. The scientific focus can include comparative or evolutionary genomics studies with the DOE JGI flagship species or clusters of comparative plant species that would inform fundamental plant biology leading to new insights into plant gene function. Examples of possible projects might include high quality pan-genomes, drought- or salt-tolerant species, secondary metabolite producers, or a concentration of genomes in an undersampled area of the plant phylogeny with compelling biology. For proposals that include non-flagship species the relevance and application to BER plant science should be clearly demonstrated.

d) Plant microbiomes – We encourage projects to study the microbiomes of BER mission relevant plants. Proposals aimed at characterizing secondary metabolite biosynthetic pathways in plants and/or associated microbes are specifically encouraged, as are hypothesis-driven projects deciphering functional and phylogenetic changes of natural or synthetic communities upon manipulation of the host and/or host environment. JGI has established exometabolomic workflows that can be used to characterize root exudates and infer metabolite exchange in the rhizosphere (see Section III). We encourage proposal submitters to consider using the DOE Systems Biology Knowledgebase (KBase) to model these interactions.

III. Inter-organismal interactions:

A key focus for DOE JGI is understanding the mutualistic, competitive or antagonistic interactions among microorganisms, plants, and viruses. Projects that could address this focus include:

• Investigation of the genomic basis of microbial mutualism and microbe-microbe interactions in stable model communities, e.g. enrichment cultures or synthetic communities
• Large-scale genome sequencing, genome mining, functional activation and exometabolomic analysis of secondary metabolites to infer function in inter-organismal interactions
• Function-driven single-cell genomics and metagenomics, e.g. sequencing of stable isotope-labeled DNA or selectively sorted single cells to assign functional roles to populations within communities
• Genomic investigation of viral evolution and host specificity
• Exometabolomic analysis of the production and depletion of metabolites to infer mechanisms of resource competition and cross-feeding

IV. Microbes and communities involved in elemental cycling in terrestrial and coastal environments

Bacteria, archaea, fungi and algae are important participants in earth’s biogeochemical cycles. While a nascent understanding of nutrient cycling in marine environments exists, our understanding of these complex processes in natural terrestrial environments has lagged behind. Proposals are encouraged that will provide insight into microbial activities controlling global cycles of carbon, nitrogen, phosphorus, sulfur and metals from a broad range of terrestrial and coastal (estuarine) environments (including terrestrial-aquatic interfaces such as peat bogs, marshes, and hyporheic zones). In addition, developing multi-omics datasets to enable modeling of regulatory and metabolic processing of these elements in model microbes and microbial systems is encouraged.

V. Algal genomics

Algae are important primary producers with tremendous diversity, long evolutionary history, and exceptional potential for DOE science and applications. Significant and rapid advances in the fundamental knowledge of algal biology, the entire biomass-to-bioenergy supply chain, and algal cultivation strategies are dependent on genetic, biochemical and phenotypic information which is currently lacking. Proposals are encouraged that will expand genomic knowledge across algal diversity, that will build fundamental knowledge of algal metabolism and physiology, and which will provide insights into algal associations with other microbes and viruses.

Project Structure

CSP projects are expected to generate publicly available data that will answer important questions relevant to the target organism or environment as well as provide a substrate for broader use by the DOE research community. CSP projects have historically provided a means for user communities to assemble and interact in collaborative ways. Proposals are encouraged that involve some or all of the following features: 1) a scale and complexity that exceeds the capacity of a single lab, 2) engaging a large group of collaborators, 3) requiring DOE JGI capabilities that reach beyond genome sequencing, 4) generating data of high value to the scientific community, and 5) plans to analyze and distribute data and results through KBase.

All proposals may request up to 3 Tbp of sequence data. For multi-PI projects generating data of broad utility to the scientific community, requests of up to 10 Tbp will be considered.  Larger Tbp totals (up to 40 Tbp) will be considered for plant Illumina resequencing only, but such proposals will be evaluated separately with the anticipation that only 1 or 2 would be approved.

Requests for Pacific Biosciences long read sequencing are capped at 100 Gbp, but larger requests will be considered for multi-PI projects of high value to the scientific community.

Proposals may request DNA synthesis up to 500 kbp of synthesized DNA, and 1 Mbp of DNA constructs.

Requests for metabolomics are capped at 200 samples for polar analysis and 500 samples for nonpolar analysis of lipids and secondary metabolites.

The DOE JGI provides extensive data analysis pipelines. Applicants should present a plan for all data analysis that may be required beyond these standard pipelines. Users are encouraged to consider and describe in their proposal how KBase may be used or extended to meet these needs.  KBase integrates a variety of data and analysis tools, from the Department of Energy and other public services, into an easy-to-use platform that leverages scalable computing infrastructure to perform sophisticated systems biology analyses. Additionally, applicants interested in collaborating with the National Microbiome Data Collaborative (NMDC) to develop project plans aligned with making their data findable, accessible, interoperable, and reusable (FAIR) should indicate so in their proposal.

DOE JGI Capabilities

All proposals should justify why JGI capabilities are critical to success. The DOE JGI employs an evolving suite of sequencing platforms, currently comprised primarily of short read Illumina (NovaSeq and NextSeq) as well as single molecule long-read Pacific Biosciences technology (Sequel II) . The capabilities available for this call are listed below. While individual proposals may draw from one or more of these capabilities as needed to fulfill project goals, within the overall cap, the final scope is ultimately at the discretion of the DOE JGI. Successful projects frequently utilize a combination of capabilities.

Core Capabilities Include:

• De novo sequencing of fungal, algal, bacterial, archaeal, viral and plant genomes
• Resequencing for variation detection
• Microbial community shotgun DNA/RNA sequencing (not amplicon sequencing of 16S or other genes, which is no longer offered)
• Whole genome DNA methylation analysis
• Comprehensive transcriptome analysis including coding transcript annotation, non-coding RNA (both small and long ncRNA) characterization and expression profiling
• Fluorescence activated cell sorting for targeted metagenomics, single-cell genomics (bacterial and archaea only) and microbial aggregates
• DNA/gene synthesis linked to sequence data generation, including codon optimization, refactoring, and assembly of biosynthetic pathways into appropriate vector systems for expression in heterologous hosts
• Whole-genome CRISPR-based gRNA library construction and QC.
• Mass spectrometry-based metabolomics analysis of primary and secondary metabolites from plants, microorganisms, and environmental samples using targeted and untargeted approaches
• Analysis pipelines for the datasets above

The DOE JGI also has limited capacity for the following developing or resource-intensive capabilities:

• Custom analysis of DOE JGI datasets
• Chromatin analysis including mapping of histone modifications by Chromatin Immunoprecipitation (ChIP-seq), and open chromatin by Assay for Transposase-Accessible Chromatin (ATAC-seq).
• Target-enriched resequencing
• In vitro transcription factor binding site mapping by DNA affinity purification sequencing (DAP-seq). DNA/gene synthesis should also be requested for construction of affinity-tagged transcription factor clones used in the assay
• Flow cytometric sorting and genomic analysis of metabolically active microbes labeled via Bio-Orthogonal Non-Canonical Amino acid Tagging (BONCAT)
• Density centrifugation and fraction collection for stable isotope probing (SIP) metagenomic studies
• Chassis-independent recombinase assisted genome engineering (CRAGE) of genes and pathways into a set of already domesticated hosts
• Pore-based sequencing with the Oxford Nanopore MinIon or PromethIon
• Access to high-performance computing at the National Energy Research Scientific Computing Center (NERSC)
• Developing new applications and extending capabilities in KBase
