Fig. 8From: ERF49 mediates brassinosteroid regulation of heat stress tolerance in Arabidopsis thalianaA model for ERF49-mediated BR regulation of heat stress tolerance. As a transcriptional activator, ERF49 positively regulates the downstream targets of BR signal transduction to promote plant development. When plants exposed to heat stress, the expression of ERF49, a direct target gene of BZR1, was inhibited. Meanwhile, ERF49 may activate of downstream HSPs-associated suppressors (X) in BR signal transduction, which directly or indirectly inhibit the expression of HSPs under high temperature stressBack to article page
