中文摘要：

高等植物的分枝发育决定着植物地上株型系统，与植物生物量和作物产量密切相关。植物分枝发育受环境因素、遗传因素和植物激素多重调控。近年来通过对各种突变体的研究，人们对植物分枝发育调控机制的认识不断深入，克隆到了一系列重要基因。目前对于植物分枝发育调控机制的研究已成为作物分子遗传育种的重要依据。

英文摘要：

The branching development of higher plants determines plant architecture system above the ground and has direct relationship with plant biomass and crop output. The plant branching development is regulated by environmental factors, genetic factors and plant hormones as well. Recently, people＇s understanding for the adjusting mechanism of plant branching development is going deeper and deeper, via studies on various mutants. Scientists have cloned a series of important genes. Nowadays, the studies on adjusting mechanism of plant branching development has become an important reliance for crop molecular genetic breeding.
