Mapping Heat Resistance in Yeasts
In a proof-of-concept study, researchers demonstrated that a new genetic mapping strategy called RH-Seq can identify genes that promote heat resistance in the yeast Saccharomyces cerevisiae, allowing this species to grow better than its closest relative S. paradoxus at high temperatures.
First Monoploid Reference Sequence of Sugarcane
For the highly polyploid sugarcane, an international team of researchers has successfully assembled a first monoploid reference sequence using a targeted approach that focused on the gene rich part of the genome by harnessing information from a sequenced related species – sorghum.
Defining a Pan-Genome for Antarctic Archaea
Some Antarctic lakes have salinities 10 times that of seawater. By collecting and sequencing dominant haloarchaeal sequences from six hypersaline lakes, researchers focused on understanding the genomic variation in haloarchaea across East Antarctica.

Methane Flux in the Amazon
Wetlands are the single largest global source of atmospheric methane. This project aims to integrate microbial and tree genetic characteristics to measure and understand methane emissions at the heart of the Amazon rainforest.
Infections and Host-Pathogen Interactions of Chlorella
The non-photosynthetic, predatory cyanobacterium Vampirovibrio chlorellavorus is a globally important obligate pathogen of Chlorella species/strains, which are of interest as biofuel feedstocks.
Insights into Functional Diversity in Neurospora
This proposal investigates the genetic bases of fungal thermophily, biomass-degradation, and fungal-bacterial interactions in Sordariales, an order of biomass-degrading fungi frequently encountered in compost and encompassing one of the few groups of thermophilic fungi.
Data & Tools
Mining IMG/M for CRISPR-Associated Proteins
Researchers report the discovery of miniature CRISPR-associated proteins that can target single-stranded DNA. The discovery was made possible by mining the datasets in the Integrated Microbial Genomes and Microbiomes (IMG/M) suite of tools managed by the JGI. The sequences were then biochemically characterized by a team led by Jennifer Doudna’s group at UC Berkeley.
DAS Tool for Genome Reconstruction from Metagenomes
Through the JGI’s Emerging Technologies Opportunity Program (ETOP), researchers have developed and improved upon a tool that combines existing DNA sequence binning algorithms, allowing them to reconstruct more near-complete genomes from soil metagenomes compared to other methods. The work was published in Nature Microbiology.
New Software Tools Streamline DNA Sequence Design-and-Build Process
Researchers from the U.S. Department of Energy Joint Genome Institute (DOE JGI) have developed a suite of build-optimization software tools (BOOST) to streamline the design-build transition in synthetic biology engineering workflows.

FY 2019 FICUS EMSL-JGI Projects Selected
Through the EMSL-JGI FICUS calls, users can combine EMSL’s unique imaging, omics and computational resources with cutting-edge genomics, DNA synthesis and complementary capabilities at JGI. This was the sixth FICUS call between EMSL and JGI since the collaborative science initiative was formed.
Preparing for a Sequence Data Deluge
The approved CSP 2019 proposals leverage new capabilities and higher throughput in DNA sequencing, synthesis and metabolomics. Additionally, just over half of the accepted proposals come from primary investigators who have never led any previously accepted JGI proposal.
Innovative Technology Improves Our Understanding of Bacterial Cell Signaling
Cyclic di-GMP (Guanine Monophosphate) is found in nearly all types of bacteria and interacts with cell signaling networks that control many basic cellular functions. To better understand the dynamics of this molecule, researchers developed the first chemiluminescent biosensors for measuring cyclic di-GMP in bacteria through work enabled by the JGI’s Community Science Program (CSP).

Hidden Giants in Forest Soils
In Nature Communications, giant virus genomes have been discovered for the first time in a forest soil ecosystem by JGI and University of Massachusetts-Amherst researchers. Most of the genomes were uncovered using a "mini-metagenomics" approach that reduced the complexity of the soil microbial communities sequenced and analyzed.
Symbiosis a Driver of Truffle Diversity
Truffles are the fruiting bodies of the ectomycorrhizal (ECM) fungal symbionts residing on host plant roots. In Nature Ecology & Evolution, an international team sought insights into the ECM lifestyle of truffle-forming species. They conducted a comparative analysis of eight Pezizomycete fungi, including four species prized as delicacies.
Expanding Fungal Diversity, One Cell at a Time
In Nature Microbiology, a team led by JGI researchers has developed a pipeline to generate genomes from single cells of uncultivated fungi. The approach was tested on several uncultivated fungal species representing early diverging fungi.
