AI Article Synopsis
- Arabidopsis plants do not bloom in winter due to the repressive role of the FLC gene on flowering genes.
- Prolonged cold temperatures during winter lead to the silencing of the FLC gene, enabling the plant to flower in the spring.
- Research by Coustham et al. (2012) suggests that modifying a specific sequence targeted by Polycomb proteins could help plants adjust this flowering mechanism to varying climate conditions.
Article 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.
