International Journal of Molecular Sciences, Год журнала: 2023, Номер 24(7), С. 6603 - 6603

Опубликована: Апрель 1, 2023

The vast majority of agricultural land undergoes abiotic stress that can significantly reduce yields. Understanding the mechanisms plant defenses against stresses and putting this knowledge into practice is, therefore, an integral part sustainable agriculture. In review, we focus on current findings in resistance to four cardinal stressors-drought, heat, salinity, low temperatures. Apart from description newly discovered signaling stress, review also focuses importance primary secondary metabolites, including carbohydrates, amino acids, phenolics, phytohormones. A meta-analysis transcriptomic studies concerning model Arabidopsis demonstrates long-observed phenomenon stressors induce different signals effects at level gene expression, but genes whose regulation is similar under most still be traced. analysis further reveals transcriptional modulation Golgi-targeted proteins response heat stress. Our highlights several are similarly regulated all conditions. These support central role phytohormones response, some these has not yet been studied. Finally, provides information about major European crop plants-wheat, sugar beet, maize, potatoes, barley, sunflowers, grapes, rapeseed, tomatoes, apples.

Novel Strategies for Designing Climate‐Smart Crops to Ensure Sustainable Agriculture and Future Food Security

Journal of Sustainable Agriculture and Environment, Год журнала: 2025, Номер 4(2)

Опубликована: Март 31, 2025

ABSTRACT To fulfil food and nutritional demand for nine billion people by the mid‐21st century, global production must increase 60% regardless of challenges such as environmental pollution, water scarcity land degradation. Climate change exacerbates frequency intensity biotic abiotic stresses, which, in turn, severely compromise crop yields, jeopardize supply, deteriorate sustainable development goals achieving safety, limit climate‐smart production. Current consumption practices negatively influence environment, posing a major threat to ecosystem human health. Addressing these critical issues achieve agriculture necessitates designing future crops employing cutting‐edge breeding strategies enhanced productivity with minimal footprints. This endeavour requires comprehensive understanding plant stress adaptation, signalling pathways mitigation mechanisms. In this review, we first explain diverse impacts ongoing climate events on Subsequently, outline various tackle change, including agronomic practices, advanced technologies physiological molecular mechanisms tolerance. We also discuss engineering superior tolerance disease resistance nurturing healthy microbial partnerships between plants soil ensure nutrition security current populations amidst mounting challenges.

Computational Metabolomics Tools Reveal Metabolic Reconfigurations Underlying the Effects of Biostimulant Seaweed Extracts on Maize Plants under Drought Stress Conditions

Metabolites, Год журнала: 2022, Номер 12(6), С. 487 - 487

Опубликована: Май 27, 2022

Drought is one of the major abiotic stresses causing severe damage and losses in economically important crops worldwide. decreases plant water status, leading to a disruptive metabolic reprogramming that negatively affects growth yield. Seaweed extract-based biostimulants show potential as sustainable strategy for improved crop health stress resilience. However, cellular, biochemical, molecular mechanisms governing agronomically observed benefits seaweed extracts on plants are still poorly understood. In this study, liquid chromatography-mass spectrometry-based untargeted metabolomics approach combined with computational strategies was applied unravel 'stamps' define effects greenhouse-grown maize (Zea mays) under drought conditions. We mass spectral networking, substructure discovery, chemometrics, pathway analyses mine interpret generated data. The results showed application induced alterations different pathways primary secondary metabolism, such phenylpropanoid, flavonoid biosynthesis, fatty acid amino acids pathways. These changes involved increasing levels phenylalanine, tryptophan, coumaroylquinic acid, linolenic metabolites. known some various biochemical physiological events lead enhanced resistance traits. latter include root growth, alleviation oxidative stress, water, nutrient uptake. Moreover, study demonstrates use networking annotating metabolome. Furthermore, reveal remodeling subsequently readjusting towards alleviation, example, by height diameter through foliar application. Such insights add ongoing efforts elucidating modes action biostimulants, extracts. Altogether, our contributes fundamental scientific knowledge necessary development industry aiming food security.

Effects of Chilling Stress on Morphological, Physiological, and Biochemical Attributes of Silage Corn Genotypes during Seedling Establishment

Plants, Год журнала: 2022, Номер 11(9), С. 1217 - 1217

Опубликована: Апрель 29, 2022

Chilling stress is one of the major abiotic stresses which hinder seedling emergence and growth. Herein, we investigated effects chilling/low temperature on morphological, physiological, biochemical attributes two silage corn genotypes during establishment phase. The experiment was conducted in a growth chamber, seedlings Yukon-R A4177G-RIB were grown at optimum up to V3 stage then subjected five regimes (25 °C as control, 20 °C, 15 10 5 °C) for days. After treatment, parameters recorded. Results indicated that temperatures lower significantly affected growth, photosynthesis system, reactive oxygen species (ROS) accumulation, antioxidant enzyme activities. Changes seedlings’ order 25 > irrespective genotypes. chlorophyll content, photosynthetic rate, maximal photochemical efficiency PS-II (Fv/Fm) drastically decreased under chilling conditions. Moreover, induced accumulation hydrogen peroxide (H2O2)and malonaldehyde (MDA) contents. Increased proline content enzymatic antioxidants, including superoxide dismutase (SOD), catalase (CAT), ascorbate (APX), found alleviate oxidative damage stress. However, genotype exhibited better adaption than A4177G3-RIB. showed higher activities A4177G3-RIB severe conditions (temperature ≤ °C). Similarly, expressed low temperature-induced ROS accumulation. Furthermore, interaction between treatment In summary, present study has shown adaptation resilience against stress, therefore could be considered potential candidate boreal climate.

Maize multi-omics reveal leaf water status controlling of differential transcriptomes, proteomes and hormones as mechanisms of age-dependent osmotic stress response in leaves

Stress Biology, Год журнала: 2024, Номер 4(1)

Опубликована: Март 18, 2024

Abstract Drought-induced osmotic stress severely affects the growth and yield of maize. However, mechanisms underlying different responses young old maize leaves to remain unclear. To gain a systematic understanding age-related responses, we compared osmotic-stress-induced changes in ages using multi-omics approaches. After short-term stress, suffered more severe water deficits than leaves. The adjustments transcriptomes, proteomes, hormones response were dynamic Metabolic activities, signaling pathways, (especially abscisic acid) responded an age-dependent manner. We identified multiple functional clusters genes proteins with potential roles adaptation. Old significantly accumulated such as dehydrin, aquaporin, chaperones cope accompanied by senescence-like cellular events, whereas exhibited effective conservation strategy mainly hydrolyzing transitory starch increasing proline production. individual are primarily determined their intracellular status, resulting differential hormones. This study extends our plant stress.
