Protein Phosphatase 2A Catalytic Subunit PP2A-1 Enhances Rice Resistance to Sheath Blight Disease

Rice Sheath Blight Disease Resistance Identified in Oryza spp. Accessions

Protein phosphatase 2A (PP2A) inhibitor CIP2A indicates resistance to radiotherapy in rectal cancer

Preoperative (chemo)radiotherapy, (C)RT, is an essential part of the treatment of rectal cancer patients, but tumor response to this therapy among patients is variable. Thus far, there are no clinical biomarkers that could be used to predict response to (C)RT or to stratify patients into different preoperative treatment groups according to their prognosis. Overexpression of cancerous inhibitor ...

Mapping and validation of QTLs for rice sheath blight resistance

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...

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 ...

Screening Oryza Species Plants for Rice Sheath Blight Resistance

Sheath blight of rice (Oryza sativa L.) is a major rice disease throughout the world including the southern United States. This disease, which is caused by Rhizoctonia solani Kühn (teleomorph: Thanatephorus cucumeris (Frank) Donk), was first reported in 1910 and now occurs throughout temperate and tropical production areas, being most prominent where rice is grown under intense, high-fertility ...
