Abstract excerpt
The molecular mechanisms governing phenological characteristics and local adaptation in woody perennials remain largely unexplored. Here, we identified that AGAMOUS-LIKE 80 (PtoAGL80.5) and FLOWERING TIME CONTROL PROTEIN FPA (PtoFPA.3) were simultaneously associated with photoperiod factors and bud break (BB) timing in Populus tomentosa. Transgenic experiments in growth chamber and two latitudinal field trials...
