Transcription factors (TFs) play a significant role in signal transduction networks spanning the perception of stress and expression corresponding stress-responsive genes. TFs are multi-functional proteins that may simultaneously control numerous pathways during stresses plants-this makes them powerful tools for manipulation regulatory pathways. In recent years, structure-function relationships plant involved drought associated have been defined, which prompted devising practical strategies engineering plants with enhanced tolerance. Vast data emerged on purposely basic leucine zipper (bZIP), WRKY, homeodomain-leucine (HD-Zip), myeloblastoma (MYB), drought-response elements binding proteins/C-repeat factor (DREB/CBF), shine (SHN), wax production-like (WXPL) reflect understanding their 3D structure how relates to function. Consequently, this information is useful tailored design variant enhances our functional states, such as oligomerization, post-translational modification patterns, protein-protein interactions, abilities recognize downstream target DNA sequences.

To Fight or to Grow: The Balancing Role of Ethylene in Plant Abiotic Stress Responses

Plants, Год журнала: 2021, Номер 11(1), С. 33 - 33

Опубликована: Дек. 23, 2021

Plants often live in adverse environmental conditions and are exposed to various stresses, such as heat, cold, heavy metals, salt, radiation, poor lighting, nutrient deficiency, drought, or flooding. To adapt unfavorable environments, plants have evolved specialized molecular mechanisms that serve balance the trade-off between abiotic stress responses growth. These enable continue develop reproduce even under conditions. Ethylene, a key growth regulator, is leveraged by mitigate negative effects of some these stresses on plant development By cooperating with other hormones, jasmonic acid (JA), abscisic (ABA), brassinosteroids (BR), auxin, gibberellic (GA), salicylic (SA), cytokinin (CK), ethylene triggers defense survival thereby coordinating response stresses. This review describes crosstalk hormones tipping responses.

The present day's ongoing global warming and climate change adversely affect plants through imposing environmental (abiotic) stresses disease pressure. major abiotic factors such as drought, heat, cold, salinity, etc., hamper a plant's innate growth development, resulting in reduced yield quality, with the possibility of undesired traits. In 21st century, advent high-throughput sequencing tools, state-of-the-art biotechnological techniques bioinformatic analyzing pipelines led to easy characterization plant traits for stress response tolerance mechanisms by applying 'omics' toolbox. Panomics pipeline including genomics, transcriptomics, proteomics, metabolomics, epigenomics, proteogenomics, interactomics, ionomics, phenomics, have become very handy nowadays. This is important produce climate-smart future crops proper understanding molecular responses genes, transcripts, proteins, epigenome, cellular metabolic circuits resultant phenotype. Instead mono-omics, two or more (hence 'multi-omics') integrated-omics approaches can decipher well. Multi-omics-characterized be used potent genetic resources incorporate into breeding program.

Abstract Abiotic stresses such as temperature (high/low), drought, salinity, and others make the environment hostile to plants. stressors adversely affect plant growth development; thereby makes a direct impact on overall productivity. Plants confront stress by developing an internal defense system orchestrated compatible solutes, reactive oxygen species scavengers phytohormones. However, routine exposure unpredictable environmental it essential equip plants with that contributes sustainable agricultural productivity, besides imparting multi‐stress tolerance. The approach against abiotic is accomplished through breeding of tolerant cultivars. Though eco‐friendly, tedious screening crossing protocol limits its usage overcome in attaining goal global food security. Advancement technological front has enabled adoption genomic engineering approaches perform site‐specific modification genome for improving adaptability, increasing yield attributing resilience different stressors. Of editing approaches, CRISPR/Cas revolutionized biological research wider applicability crop emerged versatile tool genomes desired traits highly accurate precise manner. present study summarizes advancement manipulate novel towards high‐yielding climate‐resilient varieties.
