Plants cultivated on the Qinghai-Tibet Plateau (QTP) are exposed to high ultraviolet radiation intensities, so they require effective mechanisms adapt these stress conditions. UV-B is an abiotic factor that affects plant growth, development, and environmental adaptation. Elymus sibiricus a common species in alpine meadows of QTP, with high-stress resistance, large biomass, nutritional value. This plays important role establishing artificial grasslands improving degraded grasslands. In this study, radiation-tolerant radiation-sensitive E. genotypes were subjected simulated short-term (5 days, 10 days) long-term (15 20 metabolite profiles evaluated explore mechanism underlying resistance sibiricus. A total 699 metabolites identified, including 11 primary such as lipids lipid-like molecules, phenylpropanoids polyketides, organic acids their derivatives, oxygen compounds. Principal component analysis distinctly clustered samples according cultivar, indicating two exhibit distinct response stress. The results showed 14 metabolites, linoleic acid, LPC 18:2, xanthosine, 23 2-one heptamethoxyflavone, glycyrrhizin, caffeic acid differentially expressed under stress, respectively. Therefore, compounds potential biomarkers for evaluating Allantoin specific consistent expression was up-regulated genotype, thereby it can be used identify varieties resistant radiation. Different metabolic observed between genotypes. model pathways constructed metabolomic study provides reference breeding new cultivars.

This study aimed to screen the differentially expressed genes (DEGs) of Gossypium hirsutum under UV-B stress and identify significant pathways based on gene enrichment analysis results. In this study, allotetraploid crop G. was used examine changes in various physiological indexes stress, screened out all DEGs (16 kJ m-2 d-1) six leaf transcriptomes. The main were analyzed according annotation. Finally, we predicted regulatory phenylpropanoid pathway by co-expression network analysis, selected GhMYB4 for verification. Gene annotation revealed that predominantly enriched related photosynthesis secondary metabolism. Further impaired mainly damaging photosystem II (PSII) inhibiting electron transport, whereas responded synthesizing metabolites such as anthocyanins lignin. We It found be an anthocyanin negative regulator response stress.

Ultraviolet‑B (UV-B) radiation and drought are two environmental stresses that significantly reduce rice quality, yield, growth. Nevertheless, there currently few studies on the association between stress UV‑B stress. This review examined complex interactions stress, with an emphasis cumulative impact these have crop. The looks at how responds to a physiological, biochemical, molecular level, emphasizing shared signaling pathways defense mechanisms. According much literature, simultaneous exposure can synergistic effects intensify damage or cause particular adaptive reactions. Through integration of biotechnological methods advanced breeding techniques, offers strategies for developing cultivars resilient both radiation.

Abstract Different cover crop (CC) species may respond differently to the projected climate change scenarios. A study was carried out in a controlled environmental chamber evaluate early season growth and development of five CC species: cereal rye ( Secale cereale L.), triticale (x Triticosecale Wittmack), winter wheat Triticum aestivum crimson clover Trifolium incarnatum mustard Brassica juncea ). Treatments consisted two levels carbon dioxide (CO 2 ) (420 720 ppm), ultraviolet‐B (UV‐B) radiation (0 10 kJ m −2 day −1 ), temperatures (29/21°C 19/11°C day/night), their combinations. Root, shoot, physiological parameters were recorded, combined stress response index (CSRI) derived. Results indicated that higher CO (+CO had net positive effect on all species, with CSRI values ranging from 1.0 5.1. Conversely, UV‐B (+UV) negative impact, −2.9 −7.6. The most favorable environment for combination increased fall temperature elevated (+T+ impact +UV mitigated an high environment, mimicking US Midsouth. Among responsive, 151% increase root shoot dry weight under +T+ treatment 86% decrease treatment. Rye least impacted by imposed climatic stressors. These results are particular interest agricultural science community as they offer insights into developing selecting adaptable desirable morphological characteristics anticipation changing climate.

Acclimation to crop niches for thousands of years has made indigenous rice cultivars better suited stress-prone environments. Still, their response UV-B resiliency is unknown. 38 landraces were grown in cemented pots a randomised block design with three replicates under open field conditions Sambalpur University the wet season 2022. Half plants each administered radiation at panicle emergence stage an adjustable chamber permitting sunlight, and effects stress on various morpho-physiological features, such as spikelet sterility, flag leaf photosynthetic flavonoid pigment contents, lipid peroxidation activities, estimated calibration resistance. The experiment identified Swarnaprabha Lalkain most sensitive resilient respectively, differential between them was further revealed expression genes related sensitivity. Subject stress, exhibited symptoms injuries, like burns, higher loss parameters, SPAD Fv/Fm, ETR qP values, while NPQ increased only Lalkain. Exposure total phenolic contents depressing Swarnaprabha. Such effect amounted release fluorescent energy latter. levels gene families controlling activation signal transduction, OsWRKY, OsUGT, OsRLCK, OsBZIP, OsGLP, CPD photolyase similar both control condition. However, exposure overexpressed only. magnitude impact compounds pubescent hair structure could be valid indicators among tolerance.
