Geographic and Host-Associated Variations in Bacterial Communities on the Floret Surfaces of Field-Grown Broccoli.

ABSTRACT: Fresh vegetables harbor diverse bacterial populations on their surfaces. However, information on this microbiota is limited to a few types of fresh vegetables, and little is known about how it varies with geography and host condition. Here, we analyzed bacterial communities on the floret surfaces of 66 field-grown broccoli collected from 22 farms in four farming regions of Jeju Island, South Korea, using 454 pyrosequencing of 16S rRNA amplicons, and we determined their relationships to farming region and host-associated factors. Geographic variations in bacterial community composition and diversity were observed among farming regions, which partly reflected their relative humidity and insolation. The most abundant phyla were Proteobacteria, followed by Actinobacteria, Firm
