Biofilm Formation in Xanthomonas arboricola pv. pruni: Structure and Development

Xanthomonasarboricola pv. pruni (Xap) causes bacterial spot of stone fruit and almond, an important plant disease with a high economic impact. Biofilm formation is one the mechanisms that microbial communities use to adapt environmental changes survive colonize plants. Herein, biofilm by Xap was analyzed on abiotic biotic surfaces using different microscopy techniques which allowed characterization stages compared planktonic condition. All strains assayed were able form real biofilms creating organized structures comprised viable cells. in differentiated from free-living bacteria forming complex matrix-encased multicellular become surrounded network extracellular polymeric substances (EPS). Moreover, nutrient content environment growth have been shown as key factors for its development. Besides, this first work where cell involved attachment aggregation identified during progression. Our findings provide insights regarding aspects improve our understanding infection process occurred Prunus spp may help future control approaches.
