چکیده انگلیسی
Lesion mimic mutant (LMM) genes, stimulating lesion formation in the absence of pathogens, play significant roles in immune response. In this study, we characterized a rice lesion mimic mutant, lmm5, which displayed light-dependent spontaneous lesions. Additionally, lmm5 plants exhibited enhanced resistance to all of the tested races of Magnaporthe oryzae and Xanthomonas oryzae pv. oryzae (Xoo) by increasing the expression of defense-related genes and the accumulation of hydrogen peroxide. Genetic analysis showed that the lesion mimic phenotype of lmm5 was controlled by two genes, lmm5.1 and lmm5.4, which were isolated with a map-based cloning strategy. Remarkably, LMM5.1 and LMM5.4 share a 97.4% amino acid sequence identity, and they each encode a eukaryotic translation elongation factor 1A (eEF1A)-like protein. Besides, LMM5.1 and LMM5.4 were expressed in a tissue-specific and an indica-specific manner, respectively. In addition, high-throughput mRNA sequencing analysis confirmed that the basal immunity was constitutively activated in the lmm5 mutant. Taken together, these results suggest that the homologous eEF1A-like genes, LMM5.1 and LMM5.4, negatively affect cell death and disease resistance in rice.
