    Data yielded from RIViT-seq increased the number of sigma factor-gene pairs confirmed in Streptomyces coelicolor from 209 to 399. Here, grey arrows denote previously known regulation and red arrows are regulation identified by RIViT-seq; orange nodes mark sigma factors while gray nodes mark other genes. (Otani, H., Mouncey, N.J. Nat Commun 13, 3502 (2022). https://doi.org/10.1038/s41467-022-31191-w)
    Streamlining Regulon Identification in Bacteria
    Regulons are a group of genes that can be turned on or off by the same regulatory protein. RIViT-seq technology could speed up associating transcription factors with their target genes.

GreenCut2: Algorithm to ID Plant Protein Functions

Researchers use genome sequencing to inform various cellular processes in land plants and algae, including the details of photosynthesis.  Despite the access to an increasing number of plant genomes (most of which have been generated by the DOE JGI), it remains difficult to correlate protein information with function, until now.  For example, identifying the role… [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]

Volvox carteri project on Astrobiology magazine

“If you think of proteins in terms of lego bricks, Chlamydomonas already had a great lego set,” says James Umen, assistant professor in the Plant Molecular and Cellular Biology Laboratory at the Salk Institute. “Volvox didn’t have to buy a new one, and instead could experiment with what it had inherited from its ancestor.”  Read… [Read More]

Volvox carteri project on NCTimes.com Blog

The study was published in the July 9 issue of Science. It may also be pertinent to the ongoing development of algae as a biofuel petroleum replacement, a major focus of research in San Diego and at the federal level. The team compared the genome of Volvox, a multicellular spherical algae, with that of the… [Read More]

Volvox carteri project in Algae Industry Magazine

One contribution that may inform biofuels research is reported in the July 9 issue of Science, where researchers led by the DOE Joint Genome Institute (JGI) and the Salk Institute presented the 138 million nucleotide genome of Volvox carteri, a multicellular alga that captures light energy through photosynthesis. The DOE is supporting research into the… [Read More]

Volvox carteri project on Biology News Net

Prochnik points to both Volvox and Chlamydomonas as experimentally tractable model organisms where the information will be widely used, even by researchers who are not necessarily interested in Volvox biology. “Having the Volvox genome is a fantastic resource for directing further research towards our target areas of interest. With this pair of algal genomes in… [Read More]

Volvox carteri project on Genetics Times

“The fundamental developmental biology interest in studying the Volvocine algae is that a single cell ancestor has evolved multicellularity and complicated cellular processes in a short evolutionary period,” explained DOE JGI bioinformaticist and co-first author Simon Prochnik. What the team found, he said, is “an astonishing lack of innovation” in the Volvox genome when compared… [Read More]

Volvox carteri project on CORDIS Wire

This is due the fact that within the green algal order Chlamydomonadales there are closely related uni- and multicellular species, such as the two-flagellated unicellular model alga Chlamydomonas reinhardtii and its sister taxon Volvox carteri, the latter being made up of more than 2,000 cells and having a much more complex life cycle on top… [Read More]

Volvox carteri project on Medical News Today

The evolution of multicellularity occurred repeatedly and independently in diverse lineages including animals, plants, fungi, as well as green and red algae. “This transition is one of the great evolutionary events that shaped life on earth,” says co-first author Simon E. Prochnik, Ph.D., a Computationial Scientist at the DOE Joint Genome Institute. “It has generated… [Read More]

Volvox carteri project on GenomeWeb

In this week’s issue of Science, research led by investigators at the Department of Energy’s Joint Genome Institute examines the organismal complexity of the multicellular green alga Volvox carteri. Simon Prochnik et al. sequenced the Volvox genome to 11.1-fold coverage using a whole-genome shotgun approach; when compared to Chlamydomonas reinhardtii, its unicellular relative, the team… [Read More]
