摘要： The aim of this study was to analyze the resistance genes and molecular mechanisms involved in rice blast infection. The contents of seven hormones and eight biochemical indicators in the leaves and spikes were at dynamic levels after inoculation with rice blast strains over time. The mRNA and protein expression of the six genes were consistent with the transcriptome analysis results. In addition, KEGG enrichment analysis showed that Os03g0132000, Os06g0215600, and Os06g0215500 were significantly enriched in the alpha-linolenic acid metabolism KEGG pathway, whereas Os05g0311801 was significantly enriched in the zeatin biosynthesis KEGG pathway. Furthermore, Os03g0180900 and Os09g0439200 were significantly enriched in the plant hormone signal transduction KEGG pathways. Therefore, blast infection could alter the hormones, biochemical indicators, and traits of rice. Moreover, genes including Os03g0132000, Os03g0180900, and Os05g0311801 were identified as rice blast resistance genes, and the mechanism might involve alpha-linolenic acid metabolism, zeatin biosynthesis, and plant hormone signal transduction KEGG pathways.
