Numerous Biosciences Area personnel are among the 2020 Berkeley Lab Director’s Awards honorees. This annual program recognizes outstanding contributions by employees to all facets of Lab activities. A complete list of winners can be found here. The ninth annual Director’s Awards ceremony will take place (virtually) on November 12 at 3 PM.
JGI Team Describes Host-Virus Dynamics In a Microbial Mat
Previous work on microbial mats had primarily relied on culturing virus and host pairs in the laboratory to study their interactions. In The ISME Journal, a team co-led by JGI postdoctoral researcher Mária Džunková used single-cell sequencing to sequence both a cell’s genome and detect accompanying viral sequences, which would suggest the virus had been infecting the cell.

JGI Helps Make Case for Plant Pan-genomes
Flowering plants abide by the concept, “the more the merrier,” with respect to their genomes. In their base state, they are diploids with two genome copies, one from each parent. Having three or more genome copies from additional parents or duplication, also known as “polyploidy,” is common amongst flowering plants. Crop breeders have harnessed polyploidy to increase fruit and flower size, and confer stress tolerance traits. In Nature Communications, a multi-institutional team led by researchers at Spain’s Universidad de Zaragoza and the DOE Joint Genome Institute (JGI) relied on a model grass system (Brachypodium) to learn more about the origins, evolution and development of plant polyploids.

Videos Showcase Biosciences’ Response to COVID-19
For the past several months, teams of bioscientists have utilized Berkeley Lab’s world-class research facilities to contribute to the national response to COVID-19, resulting in a wide range of promising research. Four videos showcase researcher contributions from across the Biosciences Area, which aim to help address some of the many scientific challenges posed by the pandemic.
JGI Helps Conduct Antarctic Lake Time-Series Study
Through a decade-long time-series study recently reported in Microbiome, a team led by Rick Cavicchioli of Australia’s University of New South Wales and including JGI researchers found that light-harvesting bacteria in Antarctica’s Ace Lake defy the norm when it comes to nutrient cycling in polar regions. While microbial populations in other Antarctic lakes and the nearby Southern Ocean shift from phototrophs to archaea when sunlight becomes scant, Ace Lake’s bacteria instead go through a boom and bust cycle aligned with light availability.
