Molecular mechanism of Pb1-mediated panicle blast resistance in rice
Background In Japan, an average of 22 billion yen is spent annually for agrochemicals in order to control rice damage caused by the blast disease. Thus, blast resistance is one of the most important targets of rice breeding. Several blast resistance genes have been identified so far. However, many of them are effective against particular races of blast fungi only and the resistance against the ...
متن کاملOsa-miR169 Negatively Regulates Rice Immunity against the Blast Fungus Magnaporthe oryzae
miR169 is a conserved microRNA (miRNA) family involved in plant development and stress-induced responses. However, how miR169 functions in rice immunity remains unclear. Here, we show that miR169 acts as a negative regulator in rice immunity against the blast fungus Magnaporthe oryzae by repressing the expression of nuclear factor Y-A (NF-YA) genes. The accumulation of miR169 was significantly ...
متن کاملWRKY45 phosphorylation at threonine 266 acts negatively on WRKY45-dependent blast resistance in rice
WRKY45 is a central regulator of disease resistance mediated by salicylic acid signaling in rice and its activation involves phosphorylation by OsMPK6. OsMPK6 phosphorylates WRKY45 at Thr266, Ser294, and Ser299 in vitro. Phosphorylation of Ser294 and/or Ser299 is required for full activation of WRKY45, but the importance of Thr266 phosphorylation has remained unknown. Here, we report on the cha...
متن کاملAssessment of Rice Panicle Blast Disease Using Airborne Hyperspectral Imagery
Rice blast disease occurs in rice production areas all over the world and is the most important disease in Japan. Remote sensing techniques may provide a mean for detecting disease intensity for large area without being subjected to raters. This study evaluated the use of airborne hyperspectral imagery to measure the severity of panicle blast in field crops. Hyperspectral remote sensing imagery...
متن کاملGene pyramiding enhances durable blast disease resistance in rice
Effective control of blast, a devastating fungal disease of rice, would increase and stabilize worldwide food production. Resistance mediated by quantitative trait loci (QTLs), which usually have smaller individual effects than R-genes but confer broad-spectrum or non-race-specific resistance, is a promising alternative to less durable race-specific resistance for crop improvement, yet evidence...
