The two main glucan polymers cellulose and callose in plant cell wall are synthesized at the plasma membrane by cellulose or callose synthase complexes. Cellulose is the prevalent glucan in cell wall and provides strength to the walls to support directed cell expansion. By contrast, callose is mainly produced in special cell wall and exercises important functions during development and stress responses. However, the structure and precise regulatory mechanism of callose synthase complex is not very clear. This review therefore compares and analyzes the regulation of callose and cellulose synthesis, and further emphasize the future research direction of callose synthesis.
植物细胞壁中的两种主要葡聚糖聚合物纤维素和胼胝质是由纤维素或胼胝质合酶复合物在质膜上合成的。纤维素是细胞壁中普遍存在的葡聚糖，为细胞壁提供强度以支持细胞的定向扩展。相比之下，胼胝质主要在特殊的细胞壁中产生，并在发育和应激反应中发挥重要作用。然而，胼胝质合酶复合物的结构和精确调控机制尚不清楚。因此，本综述比较和分析了胼胝质和纤维素合成的调控，并进一步强调了胼胝质合成的未来研究方向。
