Abstract
The vascular bundle formation in rice leaves occurs one-dimensionally at the base area of the leaf according to developmental program; therefore, we have used rice plants as a model in order to understand the mechanism of vascular bundle formation. Previously, we reported the commissural vein excessive1 (coe1) mutant in which narrower intervals of commissural veins are formed and some commissural veins show the cluster-like structure. In this paper, we revealed that COE1 encodes an LRR-RLK from the complementation test with coe1-1. The intensive analysis of the phenotype of coe1 plants suggested that COE1 is involved in some of brassinosteroid signaling. Based on results obtained so far, we will discuss on the initiation of commissural veins governed by COE1.
