Abstract

Nonpathogenic strain ARK-1 of Rhizobium vitis has antagonistic activity against a tumorigenic (Ti) strain of R. vitis and works as a biocontrol agent, but the temporal dynamics of the bacterial colonization in plants needs to be understood. Here we showed that the incidence of galls induced by Ti strain was reduced to about 60% when both upper and lower positions on the grapevine stem were inoculated with ARK-1 3 cm from the site that was inoculated with Ti 5 days later. A bacterial cell detection assay in the grapevine tissue revealed that ARK-1 moved at least 3 cm in 5 days.
