摘要

snf1相关蛋白激酶2 (SnRK2)家族成员是植物特异性丝氨酸或苏氨酸激酶，在植物对非生物胁迫的反应中起关键作用。该植物特异性激酶家族成员包括植物脱落酸(ABA)反应的关键调节因子(SnRK2)。植物器官的发育主要受SnRK2和植物激素脱落酸(ABA)的相互作用控制。最近的研究揭示了SnRK2和ABA信号在植物对干旱和芽生长等胁迫的反应中的协同联系。SnRK2激酶在控制SnRK1和植物发育中起双重作用。SnRK2激酶的双重作用促进植物在最佳条件和无ABA条件下的生长，同时抑制植物对ABA的反应。在这篇综述中，我们揭示了aba激活的SnRK2激酶在植物中的作用及其生理机制。

ABA activated SnRK2 kinases: an emerging role in plant growth and physiology

ABSTRACT Members of the SNF1-related protein kinase 2 (SnRK2) family are plant-specific serine or threonine kinases that play a pivotal role in the response of plants to abiotic stresses. Members of this plant-specific kinase family have included a critical regulator (SnRK2) of abscisic acid (ABA) response in plants. Plant organ development is governed substantially by the interaction of the SnRK2 and the phytohormone abscisic acid (ABA). Recent research has revealed a synergistic link between SnRK2 and ABA signaling in a plant’s response to stress such as drought and shoot growth. SnRK2 kinases play a dual role in the control of SnRK1 and the development of a plant. The dual role of SnRK2 kinases promotes plant growth under optimal conditions and in the absence of ABA while inhibiting the growth of plants in response to ABA. In this review, we have uncovered the roles of ABA-activated SnRK2 kinases in plants, as well as their physiological mechanisms.
