In PNAS this week: role for RTP4 gene in severe malaria, other infections; CRISPR-based approach to alter gene expression; and more.

The researchers proposed specific functions for transporters, enzymes, and uncharacterized protein families and identified several potential DNA repair proteins.

Researchers also used citrus genomes to untangle their relationships and suggest new taxonomic classifications.

In PNAS this week: red algae Porphyra umbicalis genome, deep neural network model for sequencing peptides, and more.

The researchers have published more than a thousand reference genomes that fill phylogenetic gaps in the tree of life.

Nigel Mouncey joined the JGI in March from Dow AgroSciences and is interested in broadening the user base and scope of JGI's research. 

Giant viruses may have developed from smaller viruses while also vacuuming up host genes, according to Ars Technica.

A quarter of the polar alga genome harbors highly divergent alleles, an international research team reported.

Researchers took two complementary approaches to assemble the Xenopus laevis genome — whole-genome and long-insert clone-based end sequencing.

A Joint Genome Institute team of researchers uncovered evidence of some 125,000 viruses from within 5 terabases of metagenomic data.
