Metabolite profiles of rice cultivars containing bacterial blight-resistant genes are distinctive from susceptible rice.
The metabolic changes of bacterial blight-resistant line C418/Xa23 generated by molecular marker-assisted selection (n= 12), transgenic variety C418-Xa21 generated by using the Agrobacterium-mediated system (n= 12), and progenitor cultivar C418 (n= 12) were monitored using gas chromatography/mass spectrometry. The validation, discrimination, and establishment of correlative relationships betwee...
متن کاملInheritance of resistance to bacterial blight in 21 cultivars of rice.
ABSTRACT Genetic analysis for resistance to bacterial blight (Xanthomonas oryzae pv. oryzae) of 21 rice (Oryza sativa L.) cultivars was carried out. These cultivars were divided into two groups based on their reactions to Philippine races of bacterial blight. Cultivars of group 1 were resistant to race 1 and those of group 2 were susceptible to race 1 but resistant to race 2. All the cultivars ...
متن کاملEffect of Rice Blast and Sheath Blight on Physical Properties of Selected Rice Cultivars
Cereal Chem. 77(5):535–540 Observations in 1997 indicated a significant reduction in kernel bulk density and head rice yield of rice cultivar LaGrue due to blast (Pyricularia grisea). A more detailed study on rice cultivar M202 in 1998 confirmed such observations but it also showed negative effects of blast on other physical properties of rice. Rough rice from blast-infected panicles was drier ...
متن کاملDetection of bacterial blight resistance genes in basmati rice landraces.
Aromatic basmati rice is vulnerable to bacterial blight disease. Genes conferring resistance to bacterial blight have been identified in coarse rice; however, their incorporation into basmati varieties compromises the prized basmati aroma. We identified bacterial blight resistance genes Xa4, xa5, Xa7, and xa13 in 52 basmati landraces and five basmati cultivars using PCR markers. The Xa7 g...
متن کاملStudy of Biochemical and Molecular Changes of Iranian Rice Cultivars in Interaction with Bacterial Pathogen Xanthomonas oryzae pv. oryzae Causes Leaf Blight Disease
Rice bacterial blight caused by Xanthamonos oryzae pv. oryzae is one of the most destructive bacterial diseases of rice in some areas of rice cultivation in the world, especially in the tropics of Asia. The low efficiency of disease management methods, especially chemical methods, has led to more research on recognizing resistant cultivars and understanding resistance mechanisms through the stu...
