Fine-tuning wheat development for the winter to spring transition.

ABSTRACT: The coordination of floral developmental stages with the environment is important for reproductive success and optimization of crop yields. The timing of different developmental stages contributes to final yield potential, with optimal adaptation enabling development to proceed without being impacted by seasonal weather events, including frosts or end-of-season drought. Here, we characterize the role of FLOWERING LOCUS T 3 (FT3) in hexaploid bread wheat (Triticum aestivum) during the early stages of floral development. By assaying the genetic diversity of landraces and modern wheat varieties, we identified a distribution of alleles for FT3 that indicated selection in modern varieties. We generated transgenic overexpression lines and found that FT3 is as powerful a florigen as FT1, which su
