摘要:

拟南芥(Arabidopsis thaliana)中与盐(salt)胁迫相关的基因SAL1所编码的蛋白是一种同时具有3'(2'),5'-二磷酸核苷酸酶和多磷酸肌醇1-磷酸酶活性的双功能酶。双功能酶SAL1最初被认定为逆境胁迫和脱落酸(ABA)信号响应途径的负调控因子, 参与植物对逆境胁迫响应的调控。近年来, 利用正向遗传学突变体表型筛选的方法, 越来越多的研究表明SAL1有着广泛的生物学功能。该文综述了SAL1的结构、定位和功能的研究进展, 介绍了SAL1对植物形态发育、矿质营养代谢、逆境响应以及植物激素信号调节等产生的影响及相关机制, 并提出未来的研究方向。

Abstract:

SAL1 was previously identified as a negative regulator of stress and abscisic acid (ABA) signaling that mediates the Arabidopsis response to adverse environmental stresses. Forward genetic methods have produced a growing body of evidence showing that SAL1 has wide biological functions. Here we review the structure, location and function of SAL1 and its effect on plant morphology and development, mineral nutrition, response to adverse environmental conditions and plant hormone-signaling response in Arabidopsis. We discuss possible future directions that might provide valuable information for further research on SAL1.
