More than just a hill of beans: Phaseolus genome lends insights into nitrogen fixation
Date:6/8/2014

s without resorting to adding fertilizers or other artificial methods of providing nutrients to the soil.

The team then compared the high quality common bean genome against the sequence of its most economically important relative, soybean. They found evidence of synteny, in which a gene in one species is present in another. They also noted that the common bean's genome had evolved more rapidly than soybean's since they diverged from the last common ancestor nearly 20 million years ago.

"Improvement of common bean will require a more fundamental understanding of the genetic basis of how it responds to biotic and abiotic stresses," the team concluded. "These findings provide information on regions of the genome that have been intensely selected either during domestication or early improvement and thus provide targets for future crop improvement efforts."
