- Abstract
- The expression profile of key genes of ascorbate biosynthesis (VTC2, GPP, GalDH, GalLDH) and recycling (MDHAR1, MDHAR4, MDHAR5) was determined in response to infection with the fungal pathogen Fusarium proliferatum in garlic cultivars related (Podnebesny) and sensitive (Dubkovsky) to Fusarium rot. It was found that differences in resistance to Fusarium lead to discrepancies in the dynamics and expression of individual genes of the ascorbate pathway, as well as in ascorbate content. It was shown that in response to infection, the expression level of the MDHAR4 gene increases in the resistant cultivar and decreases in the Fusarium-sensitive accession. As infection progresses, the expression levels of the VTC2 and GalLDH genes increase significantly (higher in the cv. Dubkovsky than in the cv. Podnebesny). In both cultivars, the ascorbate content increases (1.5 times higher in the cv. Dubkovsky than in the cv. Podnebesny).
