Abstract	Genes in the FLOWERING LOCUS T (FT) family have been shown to be important in the control of the switch between vegetative and reproductive growth in several plant species. In this study, two FT orthologs were isolated from Populus simonii, a species indigenous to China and planted in North China as a shelterbelt. The orthologs were named PsFT1 and PsFT2. Phylogenetic analysis revealed that the two genes belonged to the FT gene family. PsFT1 and PsFT2 control flowering initiation in response to day-length when ectopically expressed in transgenic Arabidopsis and transgenic juvenile poplar clone T89 plants. Moreover, when poplar T89 was transformed with PsFT1 or PsFT2, flowering was induced within 40 days. Subsequently, floral meristems emerged on the flanks of the axillary inflorescence shoots. These findings suggest that PsFT1 and PsFT2 are involved in the control of the timing of flowering in Populus simonii.
