Complete genome sequences of five Variovorax strains isolated from the Populus rhizosphere and endosphere

Research output: Contribution to journal › Article › peer-review

Abstract

We report the complete genome sequences of five Variovorax strains isolated from the roots of Populus species in greenhouse and field settings. Genome sizes range from 7.44 to 7.71 Mbp and encode 6,077–6,879 predicted protein-coding genes. These genome assemblies expand the known genomic catalog of Variovorax in plant-associated environments.
