Rapid Population Flux in Bacterial Spot Xanthomonads During a Transition in Dominance Between Two Genotypes in Consecutive Tomato Production Seasons and Identification of a New Species, Xanthomonas oklahomensis sp. nov.

Abstract excerpt

In the bacterial spot of tomato disease complex, Xanthomonas euvesicatoria pv. perforans (Xep) is known to outcompete X. euvesicatoria pv. euvesicatoria (Xee). The result, over time in tomato production systems where both pathogens are present, is the anticipated displacement of Xee by Xep. In this study, we characterized the population of recovered strains from grower fields in response to a bacterial spot of...
