Abstract excerpt
In temperate and boreal perennial trees, precise timing of growth cessation under short photoperiods is essential for survival and geographic adaptation. In Populus, the circadian evening complex (EC) component EARLY FLOWERING 3 (ELF3) integrates temperature and photoperiod signals to regulate growth cessation, yet the underlying mechanism remains incompletely understood. Here, we demonstrate that the tree LUX...
