Selaginella genome project in CORDIS Wire

This genome, sequenced by the Joint Genome Institute of the U.S. Department of Energy, is expected to give scientists a better understanding of how plants of all kinds evolved over the past 500 million years. Banks, a professor of botany and plant pathology, led a team of about 100 scientists from 11 countries to sequence… [Read More]

Selaginella genome project on NPR

Probing the secrets of plants at the genetic level is all the rage these days among scientists seeking to understand how plants evolved on Earth. One of those plants is selaginella, one of the first plants to develop a system of tubes that transport water and nutrients inside a plant. Read more or listen to… [Read More]

Selaginella genome project in GenomeWeb Daily News

By sequencing the genome of the spikemoss Selaginella moellendorffii and comparing it to several other sequenced plant genomes, researchers have identified genetic patterns that correspond to different stages of plant evolution. Read more at GenomeWeb Daily News [Read More]

Sponge genome project in New Scientist

Sponges are primitive creatures with a body plan unlike that of any other living organism. They are also our most distant animal cousins. Now that their genetic make-up has finally been sequenced, it could explain one of the greatest mysteries of evolution: how single-celled organisms in the primordial oceans evolved into complex multicellular animals with… [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]

Frog genome project on QB3

When the Joint Genome Institute decided to sequence a frog genome, however, the Xenopus research community recommended X. tropicalis over X. laevis because tropicalis has half the genome size. While X. tropicalis is diploid, with two copies of each gene on 10 pairs of chromosomes, the X. laevis genome has undergone duplication and could have… [Read More]

Frog genome project on 7th Space

“Sequencing and assembling a genome is basically science infrastructure – the equivalent of building roads and bridges – and once the infrastructure is in place, everyone can benefit,” Sater said. “This work is an enormous contribution to research now in progress throughout the world, and essentially every study that uses Xenopus as a research animal… [Read More]

Volvox algae and sex evolution on Newswise

“We found that the Volvox mating locus is about five times bigger than that of Chlamydomonas,” says postdoctoral researcher and co-first author Patrick Ferris, Ph.D. “We wanted to understand the evolutionary basis of this. How did it happen? And where did these new genes come from?” To trace the origin of the added genes, the… [Read More]

Volvox algae and sex evolution on ScienceDaily

Although the genomes of Chlamydomonas and Volvox are similar in most ways, there is one glaring exception that provided the Salk researchers with an entrée into the origin of male and female sexes-the so-called mating locus that functions in much the same way as human X and Y chromosomes to determine gender. When Umen and… [Read More]

Naegleria genome project on Medical News Today

Scientists have now sequenced the genome of a weird, single-celled organism called Naegleria gruberi that is telling biologists about that transition from prokaryotes, which function just fine with all their proteins floating around in a soup, to eukaryotes, which neatly compartmentalize those proteins? The sequence, produced by the Department of Energy Joint Genome Institute (JGI),… [Read More]
