Control of specific gene expression by gibberellin and brassinosteroid.

abstract：:Peroxisomes are small organelles that house many oxidative reactions. Peroxisome proliferation is induced under multiple stress conditions, including salt stress; however, factors regulating this process are not well defined. We have identified a role for Arabidopsis (Arabidopsis thaliana) MAP KINASE17 (MPK17) in affe...
