The SnRK2 family members are plant-specific serine/threonine kinases involved in plant response to abiotic stresses and abscisic acid (ABA)-dependent plant development.

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.

Plants sense and respond to hyperosmotic stress via quick activation of sucrose nonfermenting 1–related protein kinase 2 (SnRK2).

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.

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.

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 …

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.

2020年1月2日 · SnRK2 kinases activate abiotic stress responses in plants following ABA-dependent phosphatase inhibition or ABA-independent osmotic stress signalling.

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.
