〈p〉Age-dependent development of leaf hairs (trichomes) on the abaxial (lower) leaf surface in 〈i〉Arabidopsis〈/i〉 is regulated by integration of positional and temporal cues via a transcriptional complex comprising the leaf abaxial fate determinant KAN1 and the AP2-like transcription factor TOE1 acting as a developmental timer.〈/p〉
〈p〉 〈l type="unord"〉〈li〉〈p〉AP2-like proteins, including TOE1, repress abaxial trichome formation in juvenile leaves.〈/p〉〈/li〉
〈li〉〈p〉TOE1 forms a repressive complex with KAN1.〈/p〉〈/li〉
〈li〉〈p〉KAN1- complex binds to the 3' downstream sequence of GL1, a master regulator of leaf trichome production.〈/p〉〈/li〉
〈li〉〈p〉KAN1/TOE1 represses GL1 expression through chromatin-loop mediated histone deacetylation.〈/p〉〈/li〉〈/l〉 〈/p〉〈/sec〉
