2021年4月28日 · Our findings reveal a unique initiation and amplification mechanism of SnRK2 activation in ABA signaling in higher plants. SnRK2 kinase activity is rapidly activated in response to 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.

2025年1月31日 · Plants sense and respond to hyperosmotic stress via quick activation of sucrose nonfermenting 1-related protein kinase 2 (SnRK2).

SNF1-RELATED PROTEIN KINASES 2 (SnRK2) are important components of early osmotic and salt stress signaling pathways in plants. The Arabidopsis ( Arabidopsis thaliana ) SnRK2 family comprises the abscisic acid (ABA)-activated protein kinases SnRK2.2, SnRK2.3, SnRK2.6, SnRK2.7, and SnRK2.8, and t …

2022年12月31日 · 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.

2020年1月30日 · Here, we report a critical role for B2, B3 and B4 subfamilies of Raf-like kinases (RAFs) in early osmotic stress as well as ABA signaling in Arabidopsis thaliana. B2, B3 and B4 RAFs are quickly...

2019年1月21日 · Here we report that an ancient subclass III SnRK2-based signalling module including ABA and an upstream Raf-like kinase (ARK) exclusively protects the moss Physcomitrella patens from drought.

Among these is a superfamily of sucrose non-fermenting protein kinase genes (SnRK2). This review focuses on the developments related to the activity, substrates, interacting proteins and gene regulation of SnRK2 gene family members.

2022年5月4日 · 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.

2019年8月1日 · Recent research has revealed that SnRK2s function in growth-promoting signaling pathways, suggesting that SnRK2s tightly control the yin–yang relationship between plant growth and stress responses.

SRK2D/SnRK2.2, SRK2E/SnRK2.6/OST1 and SRK2I/SnRK2.3 are redundant ABA-activated SNF1-related protein kinases 2 (SnRK2s) in Arabidopsis thaliana. We examined the role of these protein kinases in seed development and germination.

2025年1月14日 · Our findings elucidate the critical roles of CPK3/4/6/11/27 in decoding Ca 2+ signals to activate SnRK2s and demonstrate a CPK-SnRK2 kinase cascade controlling osmotic stress responses in plants.

近日，葡萄牙 Elena Baena-González 研究组在Nature Plants在线发表了一篇题为A dual function of SnRK2 kinases in the regulation of SnRK1 and plant growth的研究论文，揭示了SnRK2激酶调控SnRK1活性和植物生长的分子机制。

2020年10月19日 · While SnRK2 kinases are main drivers of ABA-triggered stress responses, we uncover an unexpected growth-promoting function of these kinases in the absence of ABA as repressors of SnRK1.

2021年8月24日 · SNF1-related kinases 2 (SnRK2s) are central regulators of plant responses to environmental cues simultaneously playing a pivotal role in the plant development and growth in favorable conditions. They are activated in response to osmotic stress and some of them also to abscisic acid (ABA), the latter being key in ABA signaling.

2022年10月9日 · SNF1-related protein kinases 2s (SnRK2s) and abscisic acid (ABA)-response element (ABRE)-binding factors (ABFs), are core components of the ABA signaling pathway involved in drought stress response. We previously reported that ADC of Poncirus trifoliata (PtrADC) functions in drought tolerance.

2019年12月13日 · A snrk2.4 knockout mutant displayed a phenotype with shorter primary root length, whereas a snrk2.10 mutant exhibited reduced lateral root number caused by the reduction of lateral root primordia and augmentation of restrained lateral root primordia.

Plant subclass III SnRK2 protein kinases are widely recognized as key regulators of abscisic acid signaling and downstream stress responses.
