| 摘 要： | β-半乳糖苷酶是一个与细胞壁降解相关的酶，广泛分布于植物组织中，参与一系列的生理生化过程，如植物的花粉发育、果实成熟及生长过程中多糖的裂解。目前，已从多种植物中分离到β-半乳糖苷酶基因。β-半乳糖苷酶基因属于多基因家族，随着研究的深入，其不同水平的转录本在不同植物的不同组织中被发现。但目前β-半乳糖苷酶在植物发育中确切的作用机制尚不明确。现介绍目前这一领域内细胞与分子生物学方面的研究进展，并结合所在课题组的研究结果进行相关探讨，为进一步研究β-半乳糖苷酶在植物中的作用机制提供新的线索。

| Abstract: | Beta galactosidase is an enzyme associated with cell wall degradation. It is widely distributed in plant tissues, taking part in a series of physiological and biochemical processes. According to recent studies, beta galactosidase genes have already been isolated from a number of plant species. Beta galactosidase genes belong to a multigene family. Increasing studies have shown that different members of beta galactosidase gene family exhibit a wide range of expression profiles throughout plants development. However, their precise biological function in vivo still remains controversial. In this review, we presented recent information on cell and molecular biology referring to the results of our investigation. This study may also facilitate us to fully understand their mechanism of action in plant. |
