Gibberellin (GA) and jasmonate (JA) are two types of phytohormones that play important roles during stamen development. For example, Arabidopsis plants deficient in either of GA or JA develop short stamens. An apparent question to ask is whether GA action and JA action during stamen filament development are independent of each other or are in a hierarchy. Recent studies showed that GA modulates the expression of genes essential for JA biosynthesis to promote JA production and high levels of JA will induce the expression of three MYB genes MYB21, MYB24 and MYB57. These three MYB genes are crucial factors for the normal development of stamen filament in Arabidopsis.
赤霉素（GA）和茉莉酸（JA）是两种植物激素，它们在雄蕊发育过程中起着重要作用。例如，GA 或 JA 缺失的拟南芥植物发育出短雄蕊。一个明显的问题是，GA 作用和 JA 作用在雄蕊花丝发育过程中是相互独立的还是存在层次关系。最近的研究表明，GA 调节 JA 生物合成所必需的基因的表达，以促进 JA 的产生，高水平的 JA 会诱导三个 MYB 基因 MYB21、MYB24 和 MYB57 的表达。这三个 MYB 基因是拟南芥雄蕊花丝正常发育的关键因素。
