Research Abstract

A major flowering inductive gene, FT (FLOWERING LOCUS T) ortholog, was expressed abundantly in peduncles rather than buds or leaves in grapevine and persimmon tree. On the other hand, a flowering repressive genes, TFL1 (TERMINAL FLOWER 1) homologs, were expressed mainly in buds on the fruit bearing shoot (current shoot). In grapevine, the expression level of FT and TFL1 were affected by existence of seeds in the neighboring berries. One of factors for biennial bearing phenomenon in fruit trees is known as a signaling from gibberellin. The expressions of genes, which are involved in the gibberellin signal transmission, altered by the existence of seeds in berries. The relationships among fruit development, seed development, and flower bud initiation could be discussed with the expression of flowering-related genes and with the gibberellin signaling.
