Terrestrial organisms and ecosystems are being exposed to new rapidly changing combinations of solar UV radiation other environmental factors because ongoing changes in stratospheric ozone climate. In this Quadrennial Assessment, we examine the interactive effects ozone, climate on terrestrial biogeochemical cycles context Montreal Protocol. We specifically assess organisms, agriculture food supply, biodiversity, ecosystem services feedbacks system. Emphasis is placed role extreme events altering exposure potential biodiversity. also address responses plants increased temporal variability radiation, change (e.g. drought, temperature) crops, driving breakdown organic matter from dead plant material (i.e. litter) biocides (pesticides herbicides). Our assessment indicates that interact various ways affect structure function ecosystems, by protecting layer, Protocol continues play a vital maintaining healthy, diverse land sustain life Earth. Furthermore, its Kigali Amendment mitigating some negative consequences limiting emissions greenhouse gases carbon sequestration vegetation pool.

Ultraviolet (UV) radiation has been considered a deleterious agent that living organisms must avoid. However, many of the acclimation changes elicited by UV induce wide range positive effects in plant physiology through elicitation secondary antioxidant metabolites and natural defenses. Therefore, this fact changed original conception as germicide potentially damaging agent, leading to concept it is worthy application harvested commodities take advantage its beneficial responses. Four decades have already passed since postharvest applications began be studied. During time, treatments successfully evaluated for different purposes, including selection raw materials, control diseases human pathogens, nutraceutical compounds, modulation ripening senescence, induction cross-stress tolerance. Besides microbicide use radiation, effect received most attention bioactive compounds defense mechanism. shown accumulation phytochemicals, ascorbic acid, carotenoids, glucosinolates, and, more frequently, phenolic compounds. The nature extent reported depend on several factors, product type, maturity, cultivar, spectral region, dose, intensity, exposure pattern. Even though recent years we greatly increased our understanding technology, some major issues still need addressed. These include defining operational conditions maximize efficacy, reducing treatment times, ensuring even exposure, especially under realistic processing conditions. This will make move beyond their status an emerging technology boost adoption industry.

Abstract Climate change and stratospheric ozone layer dynamics have altered the intensity of ultraviolet B (UV‐B) radiation, affecting growth, yield, metabolic responses major cereal crops. As a result, to meet future demand scenario for growing population health concerns, millets been recognized as important substitutes. Among them, pearl millet has shown resilience against various abiotic stresses, but its response UV‐B radiation not yet explored. Recognizing importance in present global food systems, investigation aimed analyse effect elevated (eUV‐B; ambient+7.2 kJm −2 d −1 ) on four cultivars (HHB‐272, HHB‐67, MPMH‐21, MPMH‐17) during panicle development stage grain filling under natural field conditions. The results indicated that stress growth morphology (plant height, number leaves, leaf area, length) at both stages, with less pronounced effects HHB‐272 HHB‐67. Declined indices [relative rate (RGR), absolute (AGR), net assimilation (NAR), area ratio (LAR)] revealed predominance stress. Grain yield was positively affected all cultivars, indicating better resource allocation different needs, thereby altering trade‐offs between reported our study. quality (total soluble sugars, reducing total free amino acids, starch content, protein) harvested seeds exhibited decreased index, pathway analysis metabolites identified through UHPLC‐HRMS shift photoassimilates towards fatty acid biosynthesis. These findings help understand plant pathways, potentially revealing mechanism involved eUV‐B exposure.

Both light intensity and spectrum (280-800 nm) affect photosynthesis and, consequently, the formation of reactive oxygen species (ROS) during photosynthetic electron transport. ROS, together with antioxidants, determine redox environment in tissues cells, which turn has a major role adjustment metabolism to changes environmental conditions. This process is very important since there are great spatial (latitude, altitude) temporal (daily, seasonal) conditions accompanied by fluctuations temperature, water supply, biotic stresses. The blue red spectral regimens decisive regulation because absorption maximums chlorophylls sensitivity photoreceptors. Based on recent publications, photoreceptor-controlled transcription factors such as ELONGATED HYPOCOTYL5 (HY5) cellular may have coordinated fine-tuning metabolic processes review gives an overview current knowledge light-associated control basic pathways (carbon, nitrogen, amino acid, sulphur, lipid, nucleic acid metabolism), secondary (terpenoids, flavonoids, alkaloids), related molecular mechanisms. Light condition-related reprogramming basis for proper growth development plants; therefore, its better understanding can contribute more efficient crop production future.

Photosynthetically active radiation (PAR) is an important environmental cue inducing the production of many secondary metabolites involved in plant oxidative stress avoidance and tolerance. To examine complex role PAR irradiance specific spectral components on accumulation phenolic compounds (PheCs), we acclimated spring barley (Hordeum vulgare) to different qualities (white, blue, green, red) at three irradiances (100, 200, 400 µmol m-2 s-1). We confirmed that blue light essential for PheCs leaves (in UV-lacking conditions), which underpins importance photoreceptor signals (especially cryptochrome). Increasing most effectively induced B-dihydroxylated flavonoids, probably due significantly enhanced expression F3'H gene. These changes PheC metabolism led a steeper increase antioxidant activity than epidermal UV-A shielding leaf extracts containing PheCs. In addition, examined possible miRNAs regulation gene related biosynthesis.
