Resumen
Root rot caused by Fusarium oxysporum is a serious root disease that affects the growth and yield of peanut crops worldwide. Identifying resistance genes is of great significance for both conventional and molecular breeding. At present, there are a few identified disease resistance genes, and the defense response mechanism against this pathogen remains unclear. Using transcriptome analysis techniques, 21 differentially expressed genes (DEGs) were identified in plants treated with Bacillus thuringiensis TG5 and carbendazim. Among these DEGs, the TIFY10A protein gene, pyruvate decarboxylase, and UDP glycosyltransferase 74B1 genes play an important role in early resistance to root rot in peanut plants, leading to regulatory factors that trigger immunity. Our study provides important information on the response mechanism of peanut plants to F. oxysporum-induced root rot and the protective benefits of colonization by the microbial pesticide, B. thuringiensis.
