| Research Abstract |
SP5G which might be related in floral regulation and inflorescence development have not been fully characterized. In this study, transgenic plants overexpressing SP5G were observed using a model cultivar Micro-Tom. The wild type plants came into flower approximately one month after seeding, but the flowering times in the transformants were more than three times as long as those in the wild type plants. The plant growths in the transformants were promoted compare to those in wild type plants. Thus it is suggested that SP5G has a role of floral repressor, and promotes vegetative growth.
