Abstract

Arabidopsis does not flower in winter because FLC represses flowering genes, but prolonged cold exposure silences FLC, allowing flowering in spring. How do plants recalibrate this switch to adapt to different climates? Reporting in Science, Coustham et al. (2012) found that tweaking a Polycomb target sequence may do the trick.
