Abscisic acid regulates axillary bud outgrowth responses to the ratio of red to far-red light.

abstract：:We have previously identified GAMYB, a gibberellin (GA)-regulated transcriptional activator of alpha-amylase gene expression, in aleurone cells of barley (Hordeum vulgare). To examine the regulation of GAMYB expression, we describe the use of nuclear run-on experiments to show that GA causes a 2-fold increase in the r...
