In a paper published online in advance in Nature this week, researchers in Japan and Spain show that expression of the rice FLOWERING LOCUS T ortholog Hd3a "induces strict short-day potato types to tuberize in long days." Further, the team shows that "potato floral and tuberization transitions are controlled by two different FT-like paralogs," StSP3D and StSP6A, which respond to independent environmental cues.
