Abstract

Extracellular DNA (eDNA) is an important polymeric substance that plays essential roles in cell aggregation and nutrient provision for the sessile bacteria. eDNA in bacterial biofilms was extensively studied. Here we found that eDNA also exists in symplasmata, a bacterial cell aggregate, which is different to a biofilm, in the rice enophyte Pantoea agglomerans YS19. We found that exogenous eDNA enhanced the formation and stability of symplasmata significantly, and that, exogenous eDNA also improved the stress resistance and colonization ability of the bacterium on host rice. These results strongly indicate novel roles of the eDNA in Pantoea agglomerans YS19, showing its special relation to the stress-resistance and endophyte-host association of the strain.
