水稻花药含有高浓度的赤霉素A4和A7。为了了解它们的生理作用，我们通过分析编码coparyl二磷酸合酶的基因（OsCPS）在发育中的水稻花中的表达模式来研究它们的生物合成位点。CPS mRNA在开花前1- 2d的花药中表达明显，在成熟花粉中积累。
Rice anthers contain high concentrations of gibberellins A4 and A7. To understand their physiological roles, we examined the site of their biosynthesis by analyzing the expression pattern of a gene (OsCPS) encoding coparyl diphosphate synthase in developing rice flowers. Expression was apparent in the anthers 1–2 days before flowering, and CPS mRNA accumulated in the maturing pollen.
