Specification of leaf polarity in Arabidopsis via the trans-acting siRNA pathway.

Current biology : CB - 9 May 2006

Garcia Damien, Collier Sarah A, Byrne Mary E, Martienssen Robert A

Abstract excerpt

Plants leaves develop proximodistal, dorsoventral (adaxial-abaxial), and mediolateral patterns following initiation. The Myb domain gene PHANTASTICA (PHAN) is required for adaxial fate in many plants , but the Arabidopsis ortholog ASYMMETRIC LEAVES1 (AS1) has milder effects, suggesting that alternate or redundant pathways exist . We describe enhancers of as1 with more elongate and dissected leaves. As well as...
