In Nature Plants, the JGI helped drive the discovery into the role sphagnum’s sex chromosomes play in carbon sequestration.
The undeniable power of plants, and the lessons they can teach us, are why the JGI took on the Open Green Genome Initiative in 2018 as part of its Community Science Program. A recent paper published in Nature Communications on Ceratopteris richardii marks the first published manuscript of a genome sequence generated through the OGG and solves an ongoing mystery in ferns.
In Nature, a team led by researchers at the University of Texas at Austin, the HudsonAlpha Institute for Biotechnology, and DOE Joint Genome Institute has produced a high-quality reference sequence of the complex switchgrass genome. Building off this work, researchers at all four DOE Bioenergy Research Centers—the Great Lakes Bioenergy Research Center, the Center for … Read more »
Innumerable road trips to collect hundreds of weedy green millet (Setaria viridis) plants have resulted in a Nature Biotechnology paper from researchers at the DOE Joint Genome Institute, the Danforth Center and the HudsonAlpha Institute for Biotechnology. The team generated genome sequences for nearly 600 green millet plants and released a very high quality reference S. viridis genome sequence. Analysis of these plant genome sequences also led researchers to identify a gene related to seed dispersal in wild populations for the first time. Learn more here on the JGI website
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.
