摘　要：

植物器官的大小受遗传因子和环境信号的双重调节。植物器官的生长由细胞增殖和细胞扩张两个连续的过程组成, 许多遗传调控因子通过影响这两个过程来调控器官的大小。近年来, 植物器官大小遗传调控研究取得很大的进展, 这些遗传因子与其他因子相互作用形成决定器官生长和发育的调控网络。本文从植物激素、泛素途径、细胞色素P450蛋白和microRNA等几个方面综述植物器官大小调控因子的研究进展。

Abstract:

Organ size in plants is controlled by both genetic factors and environmental signals. Organ growth occurs through the two successive processes of cell proliferation and cell expansion in plants, a number of genes influence these processes to regulate organ size. In recent years, there have been significant progress in identification genetic factors to control plant organ size, which constitute networks with other factors in regulat-ing organ size. Here we summarized the progress of major regulators of organ size from plant hormones, ubiq-uitin pathway, Cytochrome P450 protein, microRNA and the other aspects in this field.

Key words: organ size; cell proliferation; cell expansion; regulators
