Plant inoculation with endophytic bacteria that normally live inside the plant without harming the host is a highly promising approach for biological disease control. The mechanism of resistance induction by beneficial bacteria is poorly understood, because pathways are only partly known and systemic responses are typically not seen. The innate endophytic community structures change in response to external factors such as inoculation, and bacterial endophytes can exhibit direct or indirect antagonism towards pathogens. Earlier we showed that resistance induction by an endophytic  Methylobacterium  sp. in potato towards  Pectobacterium atrosepticum  was dependent on the density of the inoculum, whereas the bacterium itself had no antagonistic activity. To elucidate the role of innate endophyte communities in plant responses, we studied community changes in both  in vitro  and greenhouse experiments using various combinations of plants, endophyte inoculants, and pathogens. Induction of resistance was studied in several potato ( Solanum tuberosum  L.) cultivars by  Methylobacterium  sp. IMBG290 against the pathogens  P. atrosepticum ,  Phytophthora infestans  and  Pseudomonas syringae  pv. tomato DC3000, and in pine ( Pinus sylvestris  L.) by  M. extorquens  DSM13060 against  Gremmeniella abietina.  The capacities of the inoculated endophytic  Methylobacterium  spp. strains to induce resistance were dependent on the plant cultivar, pathogen, and on the density of  Methylobacterium  spp. inoculum. Composition of the endophyte community changed in response to inoculation in shoot tissues and correlated with resistance or susceptibility to the disease. Our results demonstrate that endophytic  Methylobacterium  spp. strains have varying effects on plant disease resistance, which can be modulated through the endophyte community of the host.
