Not known; ectopic expression of LOB leads to alterations in the size and shape of leaves and floral organs and causes male and female sterility. Expressed in a band of cells at the adaxial base of all lateral organs formed from the shoot apical meristem and at the base of lateral roots. Positively regulated within the shoot apex by both ASYMMETRIC LEAVES 1 (AS1) and ASYMMETRIC LEAVES 2 (AS2/LBD6) and by KNAT1. Belongs to the LOB domain-containing protein family.
