Herbicide 2,4-dichlorophenoxyacetic acid interferes with MAP kinase signaling in Fusarium graminearum and is inhibitory to fungal growth and pathogenesis

Abstract

Herbicide 2,4-D was found to inhibit growth, DON biosynthesis, and plant infection in Fusarium graminearum. Whereas ROS accumulation and FgHog1 activation were stimulated, Gpmk1 phosphorylation was reduced by 2,4-D treatments.

Keywords

Fungal pathogenesis / MAP kinase pathways / 2,4-D / Fusarium graminearum
