摘要：

GAMYB is a GA-responsive activator of hydrolase gene expression in the aleurone layer of germinated cereal grains. We have isolated a putative GAMYB-binding protein, GMPOZ, which contains a BTB/POZ domain found in certain animal transcriptional regulators. Although BTB/POZ domain proteins are numerous in plants, very few are yet characterized. We found that GMPOZ is nuclear localized and that GMPOZ mRNA is expressed highly in anthers as well as aleurone. Transient silencing of the GMPOZ gene suggests that GMPOZ is involved in hormone responsive gene expression in aleurone.
