摘要：

Light and brassinosteroids are involved in the regulation of stem elongation in etiolated seedlings, but the molecular mechanism of their integration is not clear. Recent work in pea has shown that the dark-inducible, light-repressible small G protein, Pra2, interacts with and activates a cytochrome P450 C-2 hydroxylase involved in brassinolide biosynthesis. Thus, a novel link between light signal transduction and the endogenous levels of an important growth-promoting plant hormone has been established.
