The age-, photoperiod- and vernalization-dependent flowering regulatory pathways of the winter annual monocarpic plant Arabidopsis thaliana. The seasonal activity of chromatin-related factors promoting flowering is depicted in green, and factors repressing flowering are shown in red. Arrows and T-bars indicate promoting and repressive effects on the target activity, respectively. If characterized, catalytic activities on the targets are indicated in brackets. See main text for a detailed explanation of the pathways. Green arrow, vegetative shoot before vernalization; orange arrow, reproductive shoot after vernalization
