Abiotic stress is one of the severe stresses of environment that lowers the growth and yield
of any crop even on irrigated land throughout the world. A major phytohormone abscisic acid …

Tolerance of plants to abiotic stressors such as drought and salinity is triggered by complex
multicomponent signaling pathways to restore cellular homeostasis and promote survival …

Abiotic stresses, including drought and salinity, trigger a complex osmotic-stress and
abscisic acid (ABA) signal transduction network. The core ABA signalling components are …

Highlights•ABA triggers a robust signal network that controls stomatal closing.•Guard cell
ABA levels are controlled by biosynthesis, catabolism, and transport.•SnRK2s and CPKs are …

Drought negatively impacts plant growth and the productivity of crops around the world.
Understanding the molecular mechanisms in the drought response is important for …

SNF 1-RELATED PROTEIN KINASE 2 (SnRK2) is a family of plant-specific protein kinases
which is the key regulator of hyper-osmotic stress signaling and abscisic acid (ABA) …

The hab1-1abi1-2abi2-2pp2ca-1 quadruple mutant (Qabi2-2) seedlings lacking key
negative regulators of ABA signaling, namely, clade A protein phosphatases type 2C …

Key message We review the recent progress on ABA signaling, especially ABA signaling for
ABA-dependent gene expression, including the AREB/ABF regulon, SnRK2 protein kinase …

Advances have been made in the development of drought-tolerant transgenic plants,
including cereals. Rice, one of the most important cereals, is considered to be a critical …

Stomata, the epidermal pores for gas exchange between plants and the atmosphere, are the
major sites of water loss. During water shortage, plants limit the formation of new stoma via …
