Disease suppression on late blight in potato tissue culture by Burkholderia gladioli TRK2-2 or DL-3-amino butyric acid
초록
영어
Late blight is one of the destructive diseases causing yield loss in not only seed potato but also field potato production. For supplying virus free tubers, most seed potato is produced by tissue culture, in which application of commercial pesticides is limited. However, there are only a few bio-fungicides effective against late blight in tissue culture. In our previous study, a bacterial isolate TRK2-2 was selected as a resistance inducing agent by a greenhouse experiment. In this study it was investigated that the antagonistic effect of the bacterial isolate TRK2-2 against plant pathogens and the efficacy of the bacterial isolate against late blight in tissue culture after its pre-or post inoculation. Also, the bacterial isolate was identified by analysis of rDNA in the intergenic spacer region.
