The emerging key role of reactive sulfur species in abiotic stress tolerance in plants

Physiologia Plantarum, Journal Year: 2023, Volume and Issue: 175(3)

Published: May 1, 2023

Abstract In plants, sulfur plays a critical role in the formation of important biomolecules such as cysteine, methionine, and tripeptide glutathione. Thiol groups, composed sulfur, are essential to numerous metabolic processes. The easy reversible oxidation reduction thiol groups have drawn attention redox regulation cellular metabolism. Reactive species (RSS), including hydrogen sulfide (H 2 S), persulfides, polysulfides, synthetized all living organisms, mainly from been recognized last two decades very molecules regulation. RSS considered potent signaling molecules, being involved virtually aspects cell function. With regard stress, reactive antioxidant machinery maintain delicate balance that gets disturbed under stress conditions, wherein biosynthesis, transportation, scavenging, overall metabolism become decisive for plant survival. While oxygen nitrogen much discussed over recent years, research into signaling, relation abiotic stresses is still nascent. evolved long before species, because both metabolized by catalase, it has suggested “antioxidant” enzymes originally regulate may do so today. this review, we tried summarize generation, interaction systems discuss detail roles various stresses.

Modulation of antioxidant defense and PSII components by exogenously applied acetate mitigates salinity stress in Avena sativa

Scientific Reports, Journal Year: 2024, Volume and Issue: 14(1)

Published: Jan. 5, 2024

Abstract Salinity stress has detrimental effects on various aspects of plant development. However, our understanding strategies to mitigate these in crop plants remains limited. Recent research shed light the potential sodium acetate as a mitigating component against salinity several species. Here, we show role counteracting adverse oat ( Avena sativa ) subjected NaCl-induced stress, including its impact morphology, photosynthetic parameters, and gene expression related photosynthesis antioxidant capacity, ultimately leading osmoprotection. The five-week experiment involved subjecting four different conditions: water, salt (NaCl), acetate, combination acetate. presence NaCl significantly inhibited growth root elongation, disrupted chlorophylls carotenoids content, impaired chlorophyll fluorescence, down-regulated genes associated with defense system. Furthermore, findings reveal that when stressed were treated it partially reversed across all analyzed parameters. This reversal was particularly evident increased content proline, thereby ensuring osmoprotection for plants, even under stressful conditions. These results provide compelling evidence regarding positive development particular focus enhancement activity.

Plant-Microbe Interactions and Crop Production

Published: Jan. 1, 2024

Plants are living entities that provide food, oxygen, and habitat for other organisms in the environment. Plants, like all things, require adequate nutrition, water, sunlight to develop thrive. continually interacting with their surroundings, including microbes live soil, roots, leaves. These interactions may have a significant impact on plant health growth, as well surrounding ecosystem. Microbes specialized roles environment, managing toxicity, suppressing illness, promoting development cycling, utilizing nutrients. The between plants can be pathogenic, symbiotic, associative different impacts health. Keeping up research better understand dynamics of rhizosphere communities would sustainable farming approaches much-needed momentum. Plant microbe alter immunity, physiological functions, soil quality, ultimately leading agriculture. This chapter focuses plant-microbe communications terms nutrient uptake, stress tolerance, crop production.

Effect of seed priming with auxin on ROS detoxification and carbohydrate metabolism and their relationship with germination and early seedling establishment in salt stressed maize

BMC Plant Biology, Journal Year: 2024, Volume and Issue: 24(1)

Published: July 25, 2024

Abstract As crucial stages in the plant ontogeny, germination and seedling establishment under adverse conditions greatly determine staple crop growth productivity. In context of green technologies aiming to improve yield, seed priming is emerging as an effective approach enhance vigor performance salt stress. this study, we assess efficiency with indole-3-acetic acid (IAA) mitigating effects stress on maize ( Zea mays L.) seedlings during early stages. unprimed seeds, reduced indices, (both radicle coleoptile) growth, together decreased tissue hydration. However, using IAA significantly improved response, reflected by increased dynamics, establishment, water status. Besides, from IAA-primed seeds showed a higher activity α-amylase, resulting sugar contents roots coleoptiles salt-stressed plants. Further, IAA-seed stimulated accumulation endogenous seedlings, concomitance significant effect reactive oxygen species detoxification lipid peroxidation prevention. Indeed, our data revealed antioxidant enzyme activities, differentially regulated coleoptiles, leading activities enzymes (SOD, CAT GPX). summary, gained study further highlight potential modulating interactions between multiple signaling pathways seed, endowing enhanced sustained tolerance subsequent

Transcriptomic Insights into Salt Stress Response in Two Pepper Species: The Role of MAPK and Plant Hormone Signaling Pathways

International Journal of Molecular Sciences, Journal Year: 2024, Volume and Issue: 25(17), P. 9355 - 9355

Published: Aug. 29, 2024

Salt stress imposes significant plant limitations, altering their molecular, physiological, and biochemical functions. Pepper, a valuable herbaceous species of the Solanaceae family, is particularly susceptible to salt stress. This study aimed elucidate physiological molecular mechanisms that contribute development tolerance in two pepper (Capsicum baccatum (moderate tolerant) Capsicum chinense (salt sensitive)) through transcriptome weighted gene co-expression network analysis (WGCNA) approach provide detailed insights. A continuous increase malondialdehyde (MDA) hydrogen peroxide (H2O2) levels C. higher activities catalase (CAT), superoxide dismutase (SOD), peroxidase (POD) indicated more tissue damage than baccatum. In analysis, we identified 39 DEGs related Meanwhile, KEGG pathway revealed enrichment MAPK hormone signaling pathways, with six each. Through WGCNA, ME.red module was as positively correlated. Moreover, 10 genes, A-ARR (CQW23_24856), CHIb (CQW23_04881), ERF1b (CQW23_08898), PP2C (CQW23_15893), ABI5 (CQW23_29948), P450 (CQW23_16085), Aldedh1 (CQW23_06433), GDA (CQW23_12764), Aldedh2 (CQW23_14182), Aldedh3 (CQW23_11481), were validated by qRT-PCR. provides insights into genetic underlying pepper.

This review highlights the relationship between metabolism of reactive oxygen species (ROS), nitrogen (RNS), and H2S-reactive sulfur (RSS). These three metabolic pathways, collectively termed oxygen, nitrogen, (RONSS), constitute a conglomerate reactions that function as an energy dissipation mechanism, in addition to allowing environmental signals be transduced into cellular information. information, form proteins with posttranslational modifications or signaling metabolites derived from RONSS, serves inducer many processes for redoxtasis adjustment changing conditions which plants are subjected. Although it is thought role chemical was originally dissipation, during evolution they seem cluster RONSS that, dissipating excess excitation potential reducing potential, also fulfils essential functions play vital stress acclimation plants. Signaling occurs by synthesizing biomolecules modify activity transcription factors through thiol groups enzymes. The result series adjustments plants’ gene expression, biochemistry, physiology. Therefore, we present overview synthesis considering importance implications agronomic management, particularly on biostimulation crops.
