Apple latent spherical virus (ALSV) is a latent virus that infects to most host plants without showing any symptoms, has a relatively broad host range, and distributes in the meristematic tissues in infected plants, which are characteristics suitable for virus vector expressing foreign genes in plants. In this article, we showed that the expression of FLOERING LOCUS T (FT) gene from Arabidopsis thaliana by the ALSV vector promoted precocious flowering in several plants including apple, soybean, eustoma, and Japanese gentian. The rapid flowering system described here will be a valuable and powerful tool for efficient breeding of the plants, which have long juvenile period.
