As part of a 50-member team led by University of Maine, Carnegie Institution for Science, and East Carolina University researchers, the DOE Joint Genome Institute (DOE JGI) sequenced, assembled and annotated the genome of the red alga Porphyra umbilicalis. The algal genome offers insights into the organism’s stress-tolerance mechanisms and how that impacts its ability to fix carbon. Read more on the JGI website.
A Gene that Influences Grain Yields in Grasses
Through deep sequencing of the model grass green foxtail (Setaria viridis), researchers pinpointed a gene critical for the development of flowers that give rise to the grain. Using this information, a homologous gene in maize was identified as playing a similar role highlighting the utility of S. viridis as a model crop. Read the JGI Science Highlight.
DOE JGI Contributes to Study on Speciation in Nature
Joint Genome Institute and Duke University researchers utilized a relative of the model plant Arabidopsis to provide the first direct evidence that QTLs, genome regions on chromosomes to which genetic traits can be mapped, are a driving force behind speciation. This research appeared in in the journal Nature Ecology & Evolution. Read the JGI Science Highlight.
DOE JGI Helps Track Antarctic Adaptations in Diatoms
In Nature, a team led by University of East Anglia scientists conducted a comparative genomic analysis involving three diatoms by tapping expertise from the DOE Joint Genome Institute (JGI), who conducted all sequencing and annotation. Read more at JGI News.
First Marine Angiosperm Genome Sequence
Coastal seagrass ecosystems cover some 200,000 square kilometers. They account for an estimated 15 percent of carbon fixed in global ocean, and also impact sulfur and nitrogen cycles.As a foundational species in the coastal marine ecosystem, researchers are interested in understanding how the plant—and by extension other plants in the ecosystem—adapts to climate change. Published online January 27, 2016 in Nature – and as the cover of the journal’s February 18, 2016 issue – a European team including researchers from the DOE Joint Genome Institute (DOE JGI) sequenced a seagrass genome: that of the eelgrass Zostera marina, taken from the Archipelago Sea off Finland.
