摘      要：To gain an enhanced understanding of the mechanism by which gibberellins （GAs） regulate the growth and development of plants, it is necessary to identify proteins regulated by GA. Proteome analysis techniques have been applied as a direct, effective, and reliable tool in differential protein expressions. In previous studies, sixteen proteins showed differences in accumulation levels as a result of treatment with GA3, uniconazole, or abscisic acid （ABA）, and/or the differences between the GA-deficient semi-dwarf mutant, Tan-ginbozu, and normal cultivars. Among these proteins, aldolase increased in roots treated with GA3, was present at low levels in Tan-ginbozu roots, and decreased in roots treated with uniconazole or ABA. In a root elongation assay, the growth of aldolase-antisense transgenic rice was half of that of vector control transgenic rice. These results indicate that increases in aldolase activity stimulate the glycolytic in the GA-induced growth of roots. In among GA, aldolase, and root growth. pathway and may play an important role this review, we discuss the relationship among GA, aldolase, and root growth.
