Applying Rice Seed-Associated Antagonistic Bacteria to Manage Rice Sheath Blight in Developing Countries

Sheath Blight and Its Management in Rice

Rhizoctonia solani AG1-IA, is the most economically important disease in Texas and other southern rice-producing states. The disease is widespread and occurs every year. The disease was first reported in Japan in 1910, and was soon well established in many Asian countries (Lee and Rush, 1983). The pathogen is capable of infecting rice, soybeans, grass weeds, and hundreds of other plant species ...

Genomic Resource of Rice Seed Associated Bacteria

Plants are host to diverse microbiome that might have co-evolved since millions of years. This resident microbiota can act as extended genome by contributing in plant growth, development and protection from biotic and abiotic stresses. Rice (Oryza Sativa) is a staple food consumed by more than 50% of the world’s population. Herein we targeted the bacterial community associated with the healthy ...

Identification of Rice Genes to Tag Quantitative Resistance to Sheath Blight in Rice

The goal of this project is to develop molecular tools to control rice sheath blight disease. Toward this end, a subtracted rice copy-DNA (cDNA) (only the expressed DNA) library was created to identify differentially expressed genes at the early interface between a tolerant rice cultivar ‘Jasmine 85’ and a highly virulent Rhizoctonia solani isolate. R. solani-induced message RNAs were selected ...

study of biological control of rice sheath blight caused by rhizoctonia solani with some antagonistic bacteria in the guilan province

among 160 samples collected from rice paddy of the guilan province including rice plant, seed, rhizospher, paddy's soil, paddy's water and sclerotium of the causal agent of rice sheath blight (rhizoctonia solani), 610 bacterial strains were isolated. 71 bacterial strains (11.64%) had the ability of inhibition mycelial growth fungus in dual culture test on pda medium. according to two characteri...
