Expression pattern of the coparyl diphosphate synthase gene in developing rice anthers.
Rice anthers contain high concentrations of gibberellins A(4) and A(7). 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.
