Monocot leaves have unique features that arise early in their development. Maturing leaves protectively enclose younger leaves and the meristem, the pool of founder cells from which a leaf emerges. Through the maturation process, proximal sheath and distal blade tissues differentiate and are separated by the ligule and auricle structures. Here we review current research focusing on the contribution of gene regulatory factors and phytohormones on the patterning and differentiation of monocot leaves primarily focusing on research in the grasses (Poaceae). The 10000 members of the grasses include the true grain cereals (wheat, rice, maize, etc.), biofuel crops such as sugarcane, pasture grasses, and bamboo. They are the most studied of the monocots due to their tremendous agricultural and agronomic importance.
单子叶植物的叶子具有在其发育早期就出现的独特特征。成熟的叶子保护性地包裹着较嫩的叶子和分生组织,分生组织是叶子从中产生的起始细胞库。在成熟过程中,近端叶鞘和远端叶片组织分化,并由叶舌和叶耳结构分隔。在这里,我们综述了当前的研究,这些研究主要聚焦于基因调控因子和植物激素对单子叶植物叶子的模式形成和分化的贡献,重点是禾本科植物(禾本科)的研究。禾本科的10000个成员包括真正的谷物(小麦、水稻、玉米等)、甘蔗等生物燃料作物、牧草和竹子。由于它们具有巨大的农业和农艺重要性,它们是单子叶植物中研究最多的。
