摘要:
植物分枝是一个高度可塑的发育过程，影响植物的光捕获能力，以及开花和结子的协调性，并最终影响植物的成功繁殖。在植物分枝过程中，叶片的叶腋处首先形成腋芽，有些腋芽继而被激活产生分枝。植物分枝受基因和生长素、细胞分裂素、独角金内酯(或衍生物)等激素的控制，也受环境因素的调节。本文总结了植物分枝的特征和影响因素方面的进展。Shoot branching of plant is a high-plastic development process. Plant branching affects plants’ light harvesting potential, the synchrony of flowering and seed set, and ultimately affects the success of plants’ reproduction. In the process, axillary buds are formed in the axil of each leaf and may subsequently be activated to give branches. Plant branching is controlled by genes and plant hormones, e.g. auxins, cytokinins and strigolactones (or strigolactone derivatives), and is also environmentally regulated. In this short review, we summarize the progress in basic characters of plant branching and the factors in influencing shoot branching.
