Many plants use information on day length, which is sensed in the leaves, to time their flowering response at the shoot apical meristem (SAM). What makes this mechanism possible is a transmissible molecule called florigen, a small protein encoded by the gene FLOWERING LOCUS T (FT). Based on this knowledge, virus-induced flowering (VIF) can be applied to promote the change to the reproductive phase and to facilitate the breeding of plants with long juvenility or unsynchronized flowering time. In their study, Deng et al. (2024) describe a potato virus X (PVX)-based method to transiently deliver the florigen in tomato plants and thereby control their flowering time.
