Temperature is one of the most important cues that plants use to flower at the right time of the year—a process crucial for adaptation and reproductive success. We live in a world where climate change is already affecting our everyday lives and where, in the not too distant future, we will likely face huge challenges associated with increasing global temperatures (1). One of these challenges is to understand how flowering and growth of agricultural crops and trees will be affected by changing temperatures. The report by Lee et al. on page 628 of this issue (2), together with a recently published paper by Posé et al. (3), provide insight into the basic mechanisms controlling temperature regulation of plant growth and development.
