Abstract: Branching plays an important role in the growth of plants, and the number of branches affects the yield of crops. For ornamental plants, the number of branches affects their appreciation effect. In this paper, the factors affecting plant branching and the genes related to the branching shapes were briefly introduced, and the methods used in the study of plant branching traits were summarized, which was expected to provided a wide range of selection space and new ideas for subsequent plant branching research.

Key words: plant branch, character, RNA-Seq

摘要： 分枝性状在植物的生长过程中发挥重要作用，分枝数量会影响作物的产量，对于观赏植物而言，分枝的多少会影响其观赏效果。介绍了影响植物分枝的因素以及与植物分枝性状相关的基因，总结了前人在研究植物分枝性状时所用的方法，以期为以后的植物分枝性状的研究提供广泛的选择空间及新的思路。
