Expression of gibberellin biosynthetic gene in Japanese weeping cherry.
The expressions of gibberellin (GA) biosynthetic gene in both of the upright and the weeping types of Japanese flowering cherry (Prunus spachiana) were investigated. A part of the GA 3-beta hydroxylase gene of Prunus spachiana (Ps3bhx), which synthesizes active GAs, were amplified by real-time RT-PCR technique. The accumulation of Ps3bhx mRNA in the weeping type were much more than that in the upright type.
