Abstract/Description: | Eggplant (Solanum melongena L.) is one of the solanaceous crops of economic and cultural importance and is widely cultivated in the state of Goa, India. Eggplant cultivation is severely affected by bacterial wilt caused by Ralstonia solanacearumthat colonizes the xylemtissue. In this study, 167 bacteriawere isolated fromthe xylemof healthy eggplant, chilli, and SolanumtorvumSw. by vacuum infiltration and maceration. Amplified rDNA restriction analysis (ARDRA) grouped these xylem residing bacteria (XRB) into 38 haplotypes. Twenty-eight strains inhibited growth of R. solanacearumand produced volatile and diffusible antagonistic compounds and plant growth promoting substances in vitro. Antagonistic strainsXB86, XB169, XB177, andXB200 recorded a biocontrol efficacy greater than 85% against BWand exhibited 12%–22 % increase in shoot length in eggplant in the greenhouse screening. 16S rRNA based identification revealed the presence of 23 different bacterial genera. XRB with high biocontrol and plant growth promoting activities were identified as strains of Staphylococcus sp., Bacillus sp., Streptomyces sp., Enterobacter sp., and Agrobacterium sp.This study is the first report on identity of bacteria from the xylem of solanaceous crops having traits useful in cultivation of eggplant. |
