Complete Genome Sequence of a Novel Nonnodulating Species Isolated from L. Rhizosphere.

We report here the complete genome sequence of sp. strain ACO-34A, isolated from L. rhizosphere.

Genome Sequence of OTEC-02, Isolated from Hydrocarbon-Contaminated Soil.

OTEC-02 was isolated from hydrocarbon-contaminated soils. Whole-genome sequence analysis was performed to learn more about the strain's ability to degrade different types of recalcitrant toxic monoaromatic hydrocarbons. The genome of this bacterium revealed its genomic properties and versatile metabolic features, as well as a complete prophage.

Ensifer mexicanus sp. nov. a new species nodulating Acacia angustissima (Mill.) Kuntze in Mexico.

A new lineage of Ensifer nodulating the American legume Acacia angustissima in the tropical forest of Chiapas and Morelos, Mexico is described. Bacteria were identified as Ensifer with ssb or nolR specific primers. Phylogenetic analysis with partial sequences of the five chromosomal genes gyrA, nolR, recA, rpoB and rrs revealed that this new lineage is related to African Ensifer terangae.

Phylogenetic relationships of rhizobia based on citrate synthase gene sequences.

Partial nucleotide sequences of the citrate synthase (gltA) gene from different rhizobia genera were determined. Tree topologies based on this housekeeping gene were similar to that obtained using 16S rRNA sequences. However gltA appeared to be more reliable at determining phylogenetic relationships of closely related taxa.
