Xylosylated 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...

Novel Chitinase Gene LOC_Os11g47510 from Indica Rice Tetep Provides Enhanced Resistance against Sheath Blight Pathogen Rhizoctonia solani in Rice

Sheath blight disease (ShB), caused by the fungus Rhizoctonia solani Kühn, is one of the most destructive diseases of rice (Oryza sativa L.), causing substantial yield loss in rice. In the present study, a novel rice chitinase gene, LOC_Os11g47510 was cloned from QTL region of R. solani tolerant rice line Tetep and used for functional validation by genetic transformation of ShB susceptible japo...

Rapid Determination of Rice Cultivar Responses to the Sheath Blight Pathogen Rhizoctonia solani Using a Micro-Chamber Screening Method

Study 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...
