Draft Genome Sequence of Microvirga vignae Strain BR 3299T, a Novel Symbiotic Nitrogen-Fixing Alphaproteobacterium Isolated from a Brazilian Semiarid Region.

Microvirga vignae is a recently described species of root-nodule bacteria isolated from cowpeas grown in a Brazilian semiarid region. We report here the 6.4-Mb draft genome sequence and annotation of M. vignae type strain BR 3299. This genome information may help to understand the mechanisms underlying the ability of the organism to grow under drought and high-temperatures conditions.
