On the world stage, increase in temperatures due to global warming is already a reality that has become one of main challenges faced by scientific community. Since agriculture highly dependent on climatic conditions, it may suffer great impact short term if no measures are taken adapt and mitigate agricultural system. Plant responses abiotic stresses have been subject research numerous groups worldwide. Initially, these studies were concentrated model plants, and, later, they expanded their several economically important crops such as rice, corn, soybeans, coffee, others. However, agronomic evaluations for launching cultivars classical genetic improvement process focus, above all, productivity, historically leaving factors tolerance background. Considering importance can term, new strategies currently being sought adopted breeding programs understand physiological, biochemical, molecular environmental disturbances plants interest, thus ensuring food security. Moreover, integration approaches bringing insights breeding. We will discuss how water deficit, high temperatures, salinity exert effects plants.

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.

Salt stress negatively affects the growth, development, and yield of horticultural crops. Nitric oxide (NO) is considered a signaling molecule that plays key role in plant defense system under salt stress. This study investigated impact exogenous application 0.2 mM sodium nitroprusside (SNP, an NO donor) on tolerance physiological morphological characteristics lettuce (Lactuca sativa L.) (25, 50, 75, 100 mM). caused marked decrease yield, carotenoids photosynthetic pigments stressed plants as compared to control ones. Results showed significantly affected oxidative compounds (superoxide dismutase (SOD), peroxidase (POD), catalase (CAT) ascorbate (APX)) non-oxidative (ascorbic acid, total phenols, malondialdehyde (MDA), proline, H2O2) lettuce. Moreover, decreased nitrogen (N), phosphorous (P), potassium ions (K+) while increasing Na (Na+) leaves The increased ascorbic antioxidant enzymes (SOD, POD, CAT, APX) MDA content In addition, H2O2 leaf N control, P root K+ all treatments decreasing Na+ salt-stressed plants. These results provide evidence helps mitigate effects.

Combating the consequences of climate change is extremely important and critical in context feeding world’s population. Crop simulation models have been extensively studied recently to investigate impact on agricultural productivity food security. Drought salinity are major environmental stresses that cause changes physiological, biochemical, molecular processes plants, resulting significant crop losses. Excessive use chemicals has become a severe threat human health environment. The beneficial microorganisms an environmentally friendly method increasing yield under stress conditions. These microbes enhance plant growth through various mechanisms such as production hormones, ACC deaminase, VOCs EPS, modulate hormone synthesis other metabolites plants. This review aims decipher effect promoting bacteria (PGPB) abiotic soil associated with global (viz., drought salinity). application stress-resistant PGPB may not only help combating effects stressors, but also lead mitigation change. More thorough level studies needed future assess their cumulative influence development.
