Abstract:
Five rhizobacteria from rice rhizosphere were isolated and examined to find novel competent biocontrol agents for rice blast fungus Magnaporthe grisea and sheath blight fungus Rhizoctonia solani, the two devastating pathogens of rice. Results from in vitro trials showed that three isolates identified as Alcaligenes faecalis strain Bk1, Alcaligenes faecalis strain Kp6 and Bacillus amyloliquifaciens strain Bk9 showed tremendous antifungal activity against M. grisea, R. solani, Fusarium graminearum and Botrytis cinerea, while, two Brevibacillus laterosporus strains B9 and S6 showed significant antagonism towards Xanthomonas oryzae pv. oryzae. After 5 days of cocultivation in the two compartment petri-dishes, the mycelium growth of R. solani was significantly inhibited by fungi static volatiles produced by A. faecalis strains Bk1 and Kp6. The application of Bk1 and Kp6 strains as soil treatments respectively suppressed the rice blast disease by 72.9%, sheath blight diseases by 71%, compared to control. In addition, A. faecalis strains significantly improved plant growth, enriched mineral nutrients and enhanced the expression of defense related genes. The bioactivity mechanisms revealed that these strains were able to produce biofilm, along with other PGPR-associated traits and comprise lipopeptide biosynthetic genes in their genomes, which helped A. faecalis to serve as potential biocontrol agents.
