Abstract Amid apprehension of global climate change, crop plants are inevitably confronted with a myriad abiotic stress factors during their growth that inflicts serious threat to development and overall productivity. These stresses comprise extreme temperature, pH, high saline soil, drought stress. Among different stresses, is considered the most calamitous stressor its impact on crops' yield stability. The climate‐resilient crops withstands reduced water availability major focus scientific fraternity ensure food security sharply increasing population. Numerous studies aim recognize key regulators molecular biochemical processes associated tolerance response. A few potential candidates now as promising targets for improvement. Transcription act regulatory switch controlling gene expression diverse biological and, eventually, metabolic processes. Understanding role regulation transcription will facilitate improvement strategies intending develop deliver agronomically‐superior crops. Therefore, in this review, we have emphasized avenues can be exploited engineer plants. We discussed several factors, such basic leucine zipper (bZIP), dehydration responsive element binding (DREB), DNA one finger (DOF), heat shock factor (HSF), MYB, NAC, TEOSINTE BRANCHED1/CYCLOIDEA/PCF (TCP), WRKY. also highlighted candidate used drought‐tolerant

Crops feed the world's population and shape human civilization. The improvement of crop productivity has been ongoing for almost 10,000 years evolved from an experience-based to a knowledge-driven practice over past three decades. Natural alleles their reshuffling are long-standing genetic changes that affect how crops respond various environmental conditions agricultural practices. Decoding basis natural variation is central understanding evolution and, in turn, improving breeding. Here, we review current advances approaches used map causal variation, provide refined insights into genetics outline this knowledge promises drive development sustainable agriculture under dome emerging technologies.

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

Plant Communications, Год журнала: 2022, Номер 3(6), С. 100417 - 100417

Опубликована: Авг. 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.
