HDA6 represses the histone acetylation modification and expression of WRKY18/40 to inhibit camalexin biosynthesis in Arabidopsis.

Plant cell reports - 2 Jun 2026

Abstract excerpt

KEY MESSAGE: As a general gene repressor, HDA6 inhibits camalexin biosynthesis through decreasing histone acetylation and H3K4me3 modification of biosynthesis genes and repressing the accumulation of SA and SA-induced expression of WRKY18 and WRKY40, two regulators in camalexin biosynthesis. Camalexin, a major phytoalexin in cruciferous plants, is induced by biotic and abiotic stresses. However, it is not clear...
