 | The US Department of Energy's Joint Genome Institute announced today that they will sequence the genomes of four species of labyrinthulomycetes. These little-known marine species were selected for sequencing as the result of a proposal submitted to the competitive JGI Community Sequencing Program by a team of microbiologists led by Dr. Jackie Collier, assistant professor at the School of Marine and Atmospheric Sciences (SoMAS) at Stony Brook University. ...> Full Article |

 | People smell them, thump them and eyeball their shape. But ultimately, it's sweetness and a sense of healthy eating that lands a melon in a shopper's cart. Plant breeders now have a better chance to pinpoint such traits for new varieties, because the melon genome with hundreds of DNA markers has been mapped by scientists with Texas AgriLife Research. That means tastier and healthier melons are likely for future summer picnics. ...> Full Article |

Having partnered last year with an international team that surveyed the genomes of 12,000 individuals to find a genetic cause for gout, Johns Hopkins scientists now have shown that the malfunctioning gene they helped uncover can lead to high concentrations of blood urate that forms crystals in joint tissue, causing inflammation and pain -- the hallmark of this disease.

Researchers have completed the genome sequence of Azotobacter vinelandii, uncovering important genetic information that will contribute to a more complete understanding of the biology of this versatile, soil-living bacterium and pave the way for new applications, including the possible use of A. vinelandii for the production of other proteins. The research will be featured on the cover of the second July 2009 issue of the Journal of Bacteriology.

Our understanding of the importance of microRNAs in regulating gene expression is expanding, and with it our requirement for robust methods to measure their expression levels. Now a new method published in BioMed Central's open-access journal Genome Biology helps researchers to better understand the delicate interplay between differences in microRNA expression levels and their target genes.

A team of scientists led by Professor Dirk Eick of Helmholtz Zentrum Muenchen has identified the enzyme TFIIH kinase as an important factor in the epigenetic regulation of the cell nucleus enzyme RNA polymerase II. The findings, recently published in the renowned journal Molecular Cell, constitute a further building block for understanding the pathomechanisms of cancer and other diseases.
