Taxonomic and biosynthetic diversity of the marine actinomycete Salinispora across spatial scales.

ABSTRACT: The spatial scales of bacterial taxonomic and natural product biosynthetic diversity remain poorly understood. This is especially true at the population level, where contrasts between small and large-scale biogeographical patterns are seldom reported. To address these unknowns for the marine actinomycete genus Salinispora, we sequenced the genomes of 99 strains cultured from sediments collected within a 1 m² plot (microscale strains). Ninety-six of the microscale strains were identified as S. arenicola, suggesting that this is the most abundant species in the sediments sampled. These strains were assigned to 2 of the 11 populations identified based on 99% ANI among 61 public genomes obtained from 10 global collection sites (global strains). The populations showed e
