The Vietnamese Mekong delta is one of the largest rice-producing areas globally. Methylobacterium spp. are persistent colonizers of the rice plant and exert beneficial effects on plant growth and health. Sixty-one Methylobacterium strains belonging to seven species were predominantly isolated from the phyllosphere of rice cultivated in six Mekong delta provinces. Inoculation tests revealed that some strains exhibited plant growth-promoting activity. Moreover, three strains possessed the novel characteristics of inducing leaf bleaching and killing rice seedlings. These results revealed the complex diversity of Methylobacterium in Mekong delta rice and that healthy and productive rice cultivation requires a proper balance of Methylobacterium.
