Water, a necessary component of cell protoplasm, plays an essential role in supporting life on Earth; nevertheless, extreme changes climatic conditions limit water availability, causing numerous issues, such as the current water-scarce regimes many regions biome. This review aims to collect data from various published studies literature understand and critically analyze plants’ morphological, growth, yield, physio-biochemical responses drought stress their potential modulate nullify damaging effects via activating natural physiological biochemical mechanisms. In addition, described breakthroughs understanding how plant hormones influence phytohormonal interaction through signaling under regimes. The information for this was systematically gathered different global search engines scientific databases Science Direct, including Google Scholar, Web Science, related studies, books, articles. Drought is significant obstacle meeting food demand world’s constantly growing population. Plants cope with cellular osmotic potential, activation defense systems form antioxidant enzymes accumulation osmolytes proteins, proline, glycine betaine, phenolic compounds, soluble sugars. Phytohormones developmental processes networks, which aid acclimating plants biotic abiotic challenges and, consequently, survival. Significant progress has been made jasmonates, salicylic acid, ethylene identifying important components roles stress. Other hormones, abscisic auxin, gibberellic brassinosteroids, peptide have linked pathways ways.

Smart reprograming of plants against salinity stress using modern biotechnological tools

Critical Reviews in Biotechnology, Год журнала: 2022, Номер 43(7), С. 1035 - 1062

Climate change gives rise to numerous environmental stresses, including soil salinity. Salinity/salt stress is the second biggest abiotic factor affecting agricultural productivity worldwide by damaging physiological, biochemical, and molecular processes. In particular, salinity affects plant growth, development, productivity. Salinity responses include modulation of ion homeostasis, antioxidant defense system induction, biosynthesis phytohormones osmoprotectants protect plants from osmotic decreasing toxicity augmented reactive oxygen species scavenging. As most crop are sensitive salinity, improving salt tolerance crucial in sustaining global response trigger stress-related genes, proteins, accumulation metabolites cope with adverse consequence Therefore, this review presents an overview plants. We highlight advances modern biotechnological tools, such as omics (genomics, transcriptomics, proteomics, metabolomics) approaches different genome editing tools (ZFN, TALEN, CRISPR/Cas system) for accomplish goal "zero hunger," a sustainable development proposed FAO.

How Do Plants Respond to Combined Drought and Salinity Stress?—A Systematic Review

Plants, Год журнала: 2022, Номер 11(21), С. 2884 - 2884

Опубликована: Окт. 28, 2022

Plants are frequently exposed to one or more abiotic stresses, including combined salinity-drought, which significantly lowers plant growth. Many studies have been conducted evaluate the responses of plants salinity and drought stress. However, a meta-analysis-based systematic review has not yet. Therefore, this study analyzed how respond differently salinity-drought stress compared either alone. We initially retrieved 536 publications from databases selected 30 research articles following rigorous screening. Data on growth-related, physiological, biochemical parameters were collected these analyzed. Overall, greater negative impact growth, photosynthesis, ionic balance, oxidative balance than In some cases, had vice versa. Drought inhibited photosynthesis salinity, whereas caused imbalance Single reduced shoot biomass equally, but root drought. experienced under conditions because antioxidant levels did increase in response individual This provided comparative understanding plants’ stress, identified several gaps. More comprehensive genetic physiological needed understand intricate interplay between plants.

Soil salinity is one of the abiotic constraints that imbalance nutrient acquisition, hampers plant growth, and leads to potential loss in agricultural productivity. Salt-tolerant growth-promoting rhizobacteria (PGPR) can alleviate adverse impacts salt stress by mediating molecular, biochemical, physiological status. In present study, bacterium Bacillus mycoides PM35 showed resistance up 3 M NaCl exhibited features. Under stress, halo-tolerant B. significant traits, such as production indole acetic acid, siderophore, ACC deaminase, exopolysaccharides. Inoculation alleviated plants enhanced shoot root length under (0, 300, 600, 900 mM). The enhancing photosynthetic pigments, carotenoids, radical scavenging capacity, soluble sugars, protein content inoculated maize compared non-inoculated plants. addition, significantly boosted antioxidant activities, relative water content, flavonoid, phenolic osmolytes while reducing electrolyte leakage, H2O2, MDA control Genes conferring tolerance (CzcD, sfp, srfAA genes) were amplified PM35. Moreover, all reactions are accompanied upregulation stress-related genes (APX SOD). Our study reveals capable promoting growth increasing
