Heterologous expression of flowering locus T promotes flowering but does not affect diurnal movement in the legume .

Flowering locus T (FT) is known to promote flowering in response to photoperiodic conditions and has recently been shown to contribute to other phenomenon, such as diurnal stomatal movement. In legumes, FTs are classified into three subtypes, though the role of each subtype is not well defined. It has been reported that when FT of (FT) is heterologously expressed in , FT functions as a mobile florigen to promote flowering, similar to FT (FT). In this study, we expressed in using the promoter and showed that heterologous expression of was able to promote flowering in the plant. We also showed that expression does not affect stomatal closing nor nyctinastic leaf movement. These findings contribute to our understanding of flower development and have potential application to breeding or plant biotechnology.
