Sheath blight, caused by Rhizoctonia solani, is one of the most serious diseases of rice. Among 33 rice accessions, mainly from National Institute of Agrobiological Sciences (NIAS) Core Collection, we found three landraces from the Himalayas-Jarjan, Nepal 555 and Nepal 8-with resistance to sheath blight in 3 years' field testing. Backcrossed inbred lines (BILs) derived from a cross between Jarj...

To find a precise, efficient, and safe method to control rice sheath blight disease (caused by Rhizoctonia solani ), this study used the natural product magnolol as fungicide. Based on characteristics of cell wall-degrading enzymes (CWDEs) released R. during early stages infection, Mag@CMCS@CPSG (magnolol@carboxymethyl chitosan@carboxymethyl cellulose, pectin, sodium alginate, glycerol) film wa...

SUMMARY Sheath blight, caused by the fungus Rhizoctonia solani, is a major disease of rice world-wide, but little is known about the host response to infection. The objective of this study was to identify proteins and DNA markers in resistant and susceptible rice associated with response to infection by R. solani. Replicated two-dimensional polyacrylamide gel electrophoresis experiments were co...

Rice sheath blight disease caused by Rhizoctonia solani is one of the most devastating diseases in rice leading to heavy yield losses. Due to the polygenic nature of resistance, no major resistance gene with complete host resistance against R. solani has been reported. In this study, we have performed molecular and functional analysis of the genes associated with the major R. solani-resistance ...

Pseudomonas aeruginosa 7NSK2 induces resistance in dicots through a synergistic interaction of the phenazine pyocyanin and the salicylic acid-derivative pyochelin. Root inoculation of the monocot model rice with 7NSK2 partially protected leaves against blast disease (Magnaporthe grisea) but failed to consistently reduce sheath blight (Rhizoctonia solani). Only mutations interfering with pyocyan...

Maize banded leaf and sheath blight (BLSB) due to Rhizoctonia solani Kühn, is an increasing problem in maize production areas, particularly in China and Southeast of Asian. A genetic map containing 146 simple sequence repeat (SSR) markers and 229 F2 plants derived from the cross R 15 (resistant) × Ye 478 (susceptible) were used in this study. QTL were characterized in a population of 229 F2:4 l...
