Comparative genomics method to tag novel nitrogen-fixation genes

Nitrogen is crucial for plant growth but plants cannot harness it directly from the atmosphere. In the United States, legume crops such as soybeans and peas rely on nitrogen fertilizers to boost yields; in 2007, 13 million tons of industrially-produced fertilizers were applied. Soil bacteria such as Sinorhizobiummeliloti have a symbiotic relationship with plant hosts… [Read More]

Boosting knowledge of nitrogen-fixing bacteria

No plant is an island; interactions with complex microbial communities both above the ground and below the ground shape the plant’s growth rates and overall health. Understanding these plant-microbe interactions can lead to improvements in plant health and productivity and carbon sequestration, which can be applied toward DOE missions in bioenergy and biogeochemistry.

Toward a Better Understanding of Soil-Microbe Interactions

In the August 2011 issue of the Journal of Bacteriology, a team of researchers led by DOE JGI’s Patrick Chain at Los Alamos National Laboratory focused on a microbe that can help or harm as the case may be. Ochrobactrum anthropi thrives in a variety of habitats including polluted soil, plants and even higher mammals…. [Read More]

Rhizobial project on The West Australian

The Centre for Rhizobium Studies, the Australian side of the project led by Dr Wayne Reeve, has the task of sequencing the genomes of rhizobia selected from distinct geographic regions across the globe.The US side of the project will be run at the Joint Genome Institute, led by head of the microbial program Dr Nikos… [Read More]

JGI-Murdoch University rhizobial project

Rhizobia are soil bacteria that can form a symbiotic relationship with legumes such as common domesticated crops such as peas, beans or clovers. These symbiotic bacteria fix atmospheric nitrogen inside nodules formed on the legume roots contributing around 65% of the nitrogen currently used in agricultural production. A joint venture has been established between the… [Read More]

Soybean sequence on Australian Life Scientist

Soybean also appears to have a highly duplicated genome, with around three quarters of the genes copied in multiple locations. This is the result of genome duplications that took place approximately 59 and 13 million years ago, after which the genome underwent gene diversification and loss and numerous chromosome rearrangements. The genome was sequenced using… [Read More]

Soybean sequence on TopNews New Zealand

The complete genome of soybean, which is the world’s most important economic crop, has successfully been sequenced by American scientists, revealing some very surprising findings and opening up the potential to come up with improved strains…. Most of the study and sequencing was undertaken at the Joint Genome Institute in Walnut Creek, California. Read more… [Read More]

Soybean sequence on ENS-Newswire

Having the new soybean sequence as a reference is expected to increase the speed and reduce the costs of resequencing the 20,000 stored soybean lines.  The study was authored by Jeremy Schmutz of the Joint Genome Institute and the HudsonAlpha Genome Sequencing Center, the U.S. Department of Agriculture-Agricultural Research Service, Purdue University and the University… [Read More]

Soybean sequence in Newswise

The sequencing of the soybean genome will be announced in a paper forthcoming in the January 14 issue of the journal Nature. Authored by Jeremy Schmutz of the Joint Genome Institute and the HudsonAlpha Genome Sequencing Center and 43 other researchers from 18 institutions, the paper details results pointing to key evolutionary events that may… [Read More]

Soybean sequence on Farm and Dairy

Agricultural Research Service is USDA’s principal intramural scientific research agency. The Department of Energy’s Joint Genome Institute; Purdue University at West Lafayette, Ind.; the University of Missouri at Columbia; and the University of Arizona at Tucson also participated in the soybean sequencing project, which was supported by the National Science Foundation and USDA’s National Institute… [Read More]
