In Science Advances, JGI researchers have taken stock of the current state of microbial genomic biodiversity. Using publicly available genome sequence data generated over the past three decades, their study assesses what fraction of the microbial diversity we know about, and proposes a path forward to curate and cultivate what is still unknown.
Biosciences FY25 LDRD Projects
The projects of 23 Biosciences Area scientists and engineers received funding through the FY25 Laboratory Directed Research and Development (LDRD) program.
Sequencing the Mysterious Microbes of the San Francisco Estuary
In a new study, Environmental Genomics and Systems Biology (EGSB) Division research scientist Lauren Lui presents the first steps of her ambitious plan to catalogue the complete genomes of the microbial life found in the San Francisco Estuary near the Sacramento-San Joaquin River Delta. Using the latest sequencing technology, Lui aims to fill in a missing piece of how this sensitive, critical ecosystem is knit together. Ultimately, her work could help scientists formulate a more predictive understanding of how microbes respond to environmental changes.
An Enzyme Family that Helped Shape Nitrogen Metabolism on Our Planet
Researchers looked across many organisms to see that aminotransferase enzymes have evolved mix-and-match characteristics — creating many different ways of processing nitrogen.
When Marine Algae Get Sick: How Viruses Shape Microbe Interactions
Researchers in the Environmental Genomics and Systems Biology Division collaborated on a study to better understand the role of viruses that infect photosynthetic phytoplankton in the marine food web.
