- W2378613168 abstract "127 endophytic bacteria strains were isolated from roots, stems and leaves of healthy tobacco plant by the method of grinding separation in different growing stages, and their antagonistic activities to Phytophthora parasitica var.nicotianae were studied to fnd new endophytic bacteria for biological control. Results showed that 12 strains were antagonistic to growth of P. parasitica var.nicotianae with width of inhibitory zone above 5mm. Those isolates were assayed for antagonistic activity, fermentation activity in vitro and greenhouse experiment. Results indicated that there existed active ingredients in cell-free culture of 8 bacteria strains, among which wy2, wy11 and wy4 had the greatest antibacterial activity against P. parasitica var nicotianae with inhibition rate above 30%. Their fltrates could damage the hyphal structure of P. parasitica var. nicotianae, resulting in abnormal expansion of hyphae damage of cell wall, exosmosis of cytoplasm, collapse of hyphae cells, and slow growth of bacteria. Results of greenhouse experiments showed that strain wy11 was the most effective strain against P. parasitica var nicotianae with control effect reached 51.7%. In addition, bacterial suspensions of endophytic bacteria wy11 and cj17 had certain growth-promoting effects on tobacco plants, which could increase stem girth, leaf length and leaf width by irrigating roots. Phylogentic analysis based on 16S rDNA suggested that wy11 shared 99% homologies with B. amyloliquefaciens(AB255669). These sequences constituted a branch in phylogenetic tree. Strain wy11 was identifed as Bacillus amyloliquefaciens." @default.
