Annotated Information
Function
MYB proteins are a superfamily of transcription factors that play regulatory roles in developmental processes and defense responses in plants(1). Relevant research indicated that the GAMyb is the sole GA-regulated transcription factor required for transcriptional activation of the high-pl a-amylase promoter. We therefore postulate that GAMyb is a part of the GA-response pathway leading to a-amylase gene expression in aleurone cells(3). In a transient transactivation experiment using Arabidopsis leaf protoplasts, researchers demonstrated that the ATMYB2 proteins activate transcription of the rd22 promoter fused to the β-glucuronidase reporter gene. This results indicate that the ATMYB2 (MYB) proteins function as transcriptional activators in the dehydration- and ABA-inducible expression of the rd22 gene(4).
Expression
The expression of the MYB genes were responsive to one or multiple types of hormone and stress treatments(1). Transient expression in protoplasts indicates that the upstream ORF inhibits expression of a downstream coding sequence. Reserachers have demonstrated that anoxia, in roots, increases the ratio between the spliced and the unspliced mRNA and affects the expression of othermyb-related genes(2). RNA blot analysis revealed that GAmyb expression in isolated barley aleurone layers is up-regulated by GA. The kinetics of GAmyb expression indicates that it is an early event in GA-regulated gene expression and precedes a-amylase gene expression(3).
