International Journal of Molecular Sciences, Journal Year: 2022, Volume and Issue: 23(23), P. 14824 - 14824

Published: Nov. 26, 2022

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.

Engineering drought and salinity tolerance traits in crops through CRISPR-mediated genome editing: Targets, tools, challenges, and perspectives

Plant Communications, Journal Year: 2022, Volume and Issue: 3(6), P. 100417 - 100417

Published: Aug. 3, 2022

Prolonged periods of drought triggered by climate change hamper plant growth and cause substantial agricultural yield losses every year. In addition to drought, salinity is one the major abiotic stresses that severely affect crop health production. Plant responses involve multiple processes operate in a spatiotemporal manner, such as stress sensing, perception, epigenetic modifications, transcription, post-transcriptional processing, translation, post-translational changes. Consequently, tolerance are polygenic traits influenced genome-environment interactions. One ideal solutions these challenges development high-yielding varieties with enhanced tolerance, together improved practices. Recently, genome-editing technologies, especially clustered regularly interspaced short palindromic repeats (CRISPR) tools, have been effectively applied elucidate how plants deal saline environments. this work, we aim portray combined use CRISPR-based genome engineering tools modern genomic-assisted breeding approaches gaining momentum identifying genetic determinants complex for improvement. This review provides synopsis at morphological, physiological, molecular levels. We also highlight recent advances their understanding multi-level nature adaptations stress. Integrating CRISPR factors regulate stress-response pathways introgression beneficial develop stress-resilient crops.
