摘要
膨胀素是植物细胞生长期间释放的一种能使细胞壁松弛的蛋白质,是细胞壁伸展的关键调节剂,对细胞生长有重要作用。膨胀素由庞大的基因家族编码,分为α-、β-、γ-和δ-膨胀素。膨胀素有多种功能,研究它对搞清生长机制有着重要的意义。
Expansins are proteins secreted by plant cells, which are key regulators of wall extension during growth, and play very important role in cell growth. Expansins are commonly encoded by substantial gene families, and have been divided into four subfamilies, referred to as α, β, γ- and δ-expansins. A couple of functional roles have been described for expansins in this review. The in-depth exploration of expansins is of significance in understanding the mechanism of cell growth.
