In the cell cycle, the G1 phase can be like a prison, where plant cells are arrested, unable to divide. These cells have been arrested for different reasons, serving sentences of different lengths. So how and why did they get there?
This review presents the latest findings to provide insight into the molecular mechanisms that underlie how photoperiodic and temperature signals regulate seasonal growth in trees.
This study finds that DNA methylation and 5-methylcytosine play key roles in determining the ageing and viability of stored recalcitrant seeds.
