Drought is a global threat that affects agricultural production. Plants have evolved several adaptive strategies to cope with drought. Stomata are essential structures for plants control water status and photosynthesis rate. Stomatal closure an efficient way reduce loss improve survivability under drought conditions. The opening of stomata depend on the turgor pressure in guard cells. Three key signaling molecules, including abscisic acid (ABA), reactive oxygen species (ROS), calcium ion (Ca2+), play pivotal roles controlling stomatal closure. sense water-deficit signal mainly via leaves roots. On one hand, ABA actively synthesized root leaf vascular tissues transported other roots synthesize CLAVATA3/EMBRYO-SURROUNDING REGION RELATED 25 (CLE25) peptide, which cells promote synthesis. perceived by pyrabactin resistance (PYR)/PYR1-like (PYL)/regulatory components receptor (RCAR) receptors, inactivate PP2C, resulting activating protein kinases SnRK2s.

Dynamic environmental changes such as extreme temperature, water scarcity and high salinity affect plant growth, survival, reproduction. Plants have evolved sophisticated regulatory mechanisms to adapt these unfavorable conditions, many of which interface with hormone signaling pathways. Abiotic stresses alter the production distribution phytohormones that in turn mediate stress responses at least part through hormone- stress-responsive transcription factors. Among these, APETALA2/ETHYLENE RESPONSIVE FACTOR (AP2/ERF) family factors (AP2/ERFs) emerged key regulators various responses, they also respond hormones improved survival during conditions. Apart from participation specific stresses, AP2/ERFs are involved a wide range tolerance, enabling them form an interconnected network. Additionally, abscisic acid (ABA) ethylene (ET) help activate ABA ET dependent independent genes. While some implicated growth developmental processes mediated by gibberellins (GAs), cytokinins (CTK), brassinosteroids (BRs). The involvement adds complexity In this review, we summarize recent studies on AP2/ERF hormonal abiotic emphasis selected members Arabidopsis. addition, leverage publically available Arabidopsis gene networks transcriptome data investigate networks, providing context important clues about roles diverse controlling responses.

Abstract Protein kinases are major players in various signal transduction pathways. Understanding the molecular mechanisms behind plant responses to biotic and abiotic stresses has become critical for developing breeding climate‐resilient crops. In this review, we summarize recent progress on understanding drought, salt, cold stress responses, with a focus perception by different protein kinases, especially sucrose nonfermenting1 (SNF1)‐related (SnRKs), mitogen‐activated kinase (MAPK) cascades, calcium‐dependent (CDPKs/CPKs), receptor‐like (RLKs). We also discuss future challenges these research fields.
