Ehux – The Alga of Many Faces

Known by the researchers who sequenced it at the Department of Energy Joint Genome Institute as “The Beast”, and considered the “Flowers of the Ocean” by others, Emiliania huxleyi has proved to be a single-celled coccolithophore of many faces. The third most abundant group of phytoplankton, Ehux is the basis of most ocean food chains,… [Read More]

Ehux pangenome project in San Diego Union-Tribune

The algae are the third most abundant phytoplankton, and are a key component of the ocean food chain, nourishing animals including crustaceans, shellfish and other filter feeders.They’re characterized by their intricate shells, composed of interwoven lattices of calcium carbonate.“We kind of think of them as flowers of the ocean,” Read said. Read the full story… [Read More]

Ehux pangenome project in redOrbit

 “The Ehux genome is incredibly variable,” said study co-author Dr. Uwe John and biologist with the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI). “For example, if the genetic information of two humans is compared, an agreement of about 99 per cent is found. However, if, for example, we take two Ehux strains from… [Read More]

Targeted metagenomics approach pins down role of “wild” alga

Marine microbes play key roles in cycling carbon between the atmosphere and the ocean depths, but little is known about their populations throughout the waters. As global temperatures change, so do these populations, which in turn impacts their contributions to the carbon cycle. Researchers want to learn more about these effects, but one of the… [Read More]

Algal Lipid Pathways Linked to Those in Plants and Fungi

Red algae play an important role in carbon and nitrogen cycles in the ocean, and are potential biomass for biofuel production. However, few red algae have been studied at the genomic level to date. An international collaboration of researchers has found that some species of the extremophilic red algae Porphyra have a pathway similar to… [Read More]

GreenCut algorithm in Crop Biotech Update

Grossman and colleagues revealed that many of the GreenCut proteins are also present in ancient cyanobacteria, red algae, and diatoms. Further assessment of these proteins is expected to bring more discoveries about their functions in photosynthetic cells, and how the photosynthetic cells might be adapted to survive various environmental conditions. Read more in ISAAA’s Crop… [Read More]

GreenCut algorithm in e! Science News

Using advanced computational tools to analyze the genomes of 28 different plants and photosynthetic organisms, Grossman and his colleagues at the University of California in Los Angeles and the Joint Genome Institute of the Department of Energy were able to identify 597 proteins encoded on plant and green algal genomes, but that are not present… [Read More]

Selaginella genome project on redOrbit

Grigoriev noted that the Selaginella genome helps fill in a large gap in plant evolution from the unicellular green alga Chlamydomonas, sequenced at the DOE JGI and published in 2007, to flowering plants with vascular systems. “Selaginella occupies a phylogenetically important position for which we had no reference,” he said. “On one end of the… [Read More]

Aureococcus genome project in Knoxville News Sentinel

The research team’s study focused on one particular strand of harmful algal blooms: Aureococcus anophagefferens. Originally, the team thought this strand would be found in the deep oceans, but the researchers discovered instead that it actually thrived in the human-affected conditions of the coastal regions.

DOE JGI Highlight: First genome of a Harmful Algal Bloom species

Algae play key roles in the global carbon cycle, helping trap carbon emissions. But some algal species can bloom, discoloring coastal waters and reduce the amount of light and oxygen available in the ecosystem. To describe these events, the term “harmful algal blooms” (HABs) was introduced two decades ago to note that accumulation of algal… [Read More]
