متن کاملXylosylated Detoxification of the Rice Flavonoid Phytoalexin Sakuranetin by the Rice Sheath Blight Fungus Rhizoctonia solani.
Sakuranetin (1) is a rice flavanone-type phytoalexin. We have already reported that the metabolites from the detoxification of 1 by Pyriculariaoryzae are naringenin (2) and sternbin. In this study, we investigated whether the rice sheath blight fungus Rhizoctoniasolani, another major rice pathogen, can detoxify 1. The extract of R. solani suspension culture containing 1 was analyzed by LC-MS to...
متن کاملMolecular Characterization and Screening for Sheath Blight Resistance Using Malaysian Isolates of Rhizoctonia solani
Two field isolates of Rhizoctonia solani were isolated from infected paddy plants in Malaysia. These isolates were verified via ITS-rDNA analysis that yielded ~720 bp products of the ITS1-5.8S-ITS4 region, respectively. The sequenced products showed insertion and substitution incidences which may result in strain diversity and possible variation in disease severity. These strains showed some re...
متن کاملStudy the Efficacy of Pseudomonas fluorescens against Sheath Blight in Rice by Rhizoctonia solani
Rice (Oryza sativa) is India's pre-eminent crop, it is the most widely consumed staple food for a large part of the world's human population, especially in Asia. Moreover, the country has the biggest area under rice cultivation, as it is one of the principal food crops. India is one of the leading producers of this crop, with a production, productivity of 105.48 million tons and 2391 kg per hec...
متن کاملSensitivity to a Phytotoxin from Rhizoctonia solani Correlates with Sheath Blight Susceptibility in Rice.
ABSTRACT Sheath blight is one of the most important and intractable diseases of rice (Oryza sativa) where limited control has been achieved using traditional approaches. Quantitative inheritance, extraneous traits, and environmental factors confound genetic analysis of host resistance. A method was developed to isolate and utilize a phytotoxin from Rhizoctonia solani to investigate the genetics...
