水稻叶片倾角2是一种类似VIN3的蛋白质，通过调节叶领的细胞分裂来调节叶片角度

叶片倾斜度作为一个重要的农艺性状，对作物结构和产量有着重要的影响。为了解水稻叶片倾角的分子调控机制，鉴定了一个水稻叶片倾角2（lc 2，3等位基因）突变体，并对其功能进行了研究。与野生型植株相比，lc 2突变体由于叶片接合处近轴表皮细胞分裂增加而导致叶角增大。LC 2基因是通过定位克隆获得的，编码一种春化不敏感的3-like蛋白。LC 2的互补表达逆转了LC 2植物的扩大的叶角，证实了其在控制叶倾斜中的作用。LC 2主要在叶片发育过程中的叶片接合处表达，特别是受植物激素脱落酸、赤霉酸、生长素和油菜素类固醇的诱导。LC 2定位于细胞核中，LC 2的缺陷导致细胞分裂和衰老响应基因的表达改变，表明LC 2在调节叶倾斜和介导激素效应中起重要作用。
As an important agronomic trait, inclination of leaves is crucial for crop architecture and grain yields. To understand the molecular mechanism controlling rice leaf angles, one rice leaf inclination2 (lc2, three alleles) mutant was identified and functionally characterized. Compared to wild-type plants, lc2 mutants have enlarged leaf angles due to increased cell division in the adaxial epidermis of lamina joint. The LC2 gene was isolated through positional cloning, and encodes a vernalization insensitive 3-like protein. Complementary expression of LC2 reversed the enlarged leaf angles of lc2 plants, confirming its role in controlling leaf inclination. LC2 is mainly expressed in the lamina joint during leaf development, and particularly, is induced by the phytohormones abscisic acid, gibberellic acid, auxin, and brassinosteroids. LC2 is localized in the nucleus and defects of LC2 result in altered expression of cell division and hormone-responsive genes, indicating an important role of LC2 in regulating leaf inclination and mediating hormone effects.
