Glucose modulates the abscisic acid-inducible Rab16A gene in cereal embryos

Glucose modulates the abscisic acid-inducible Rab16A gene in cereal embryos Glucose effects on the expression of the abscisic acid-inducible Rab16A gene were examined in rice and barley embryos. Glucose feeding to rice embryos negatively affects the endogenous abscisic acid content and represses the promoter activity of the Rab16A gene. Glucose repression of the Rab16A gene takes place both at a transcriptional and a post-transcriptional level. Modulation of the abscisic acid content in rice embryos triggered by glucose did not directly influence the expression of the rice α-amylase gene RAmy3D, which is known to be under glucose control.

Abstract

Glucose effects on the expression of the abscisic acid-inducible Rab16A gene were examined in rice and barley embryos. Glucose feeding to rice embryos negatively affects the endogenous abscisic acid content and represses the promoter activity of the Rab16A gene. Glucose repression of the Rab16A gene takes place both at a transcriptional and a post-transcriptional level. Modulation of the abscisic acid content in rice embryos triggered by glucose did not directly influence the expression of the rice α-amylase gene RAmy3D, which is known to be under glucose control. The possible interaction between the glucose and abscisic acid signaling pathway is discussed.
