Effectors and environment modulating rice blast disease: from understanding to effective control

Trends Microbiol. 2024 Apr 5:S0966-842X(24)00072-6. doi: 10.1016/j.tim.2024.03.006. Online ahead of print.ABSTRACTRice blast is a highly destructive crop disease that requires the interplay of three essential factors: the virulent blast fungus, the susceptible rice plant, and favorable environmental conditions. Although previous studies have focused mainly on the pathogen and rice, recent research has shed light on the molecular mechanisms by which the blast fungus and environmental conditions regulate host resistance and contribute to blast disease outbreaks. This review summarizes significant achievements in understanding the sophisticated modulation of blast resistance by Magnaporthe oryzae effectors and the dual regulatory mechanisms by which environmental conditions influence rice resistance and virulence of the blast fungus. Furthermore, it emphasizes potential strategies for developing blast-resistant rice varieties to effectively control blast disease.PMID:38580607 | DOI:10.1016/j.tim.2024.03.006
