Rhododendron is a well-known genus consisting of commercially valuable ornamental woody plant species. Heat stress major environmental factor that affects rhododendron growth. Melatonin was recently reported to alleviate the effects abiotic on plants. However, role melatonin in plants unknown. In this study, effect exposed heat and potential underlying mechanism were investigated. Analyses morphological characteristics chlorophyll fluorescence indicated 200 μmol L-1 optimal concentration for protecting from stress. To elucidate how limits adverse high temperatures, contents, photosynthetic indices, Rubisco activity, ATP contents analyzed at 25, 35, 40°C. Compared with control, exogenous application improved electron transport rate, photosystem II I activities, under The transcriptome analysis revealed many heat-induced differentially expressed genes associated pathway; expression most these down-regulated by more melatonin-free than melatonin-treated We identified RhPGR5A, RhATPB, RhLHCB3, RhRbsA as key genes. Thus, we speculate promotes transport, improves Calvin cycle enzyme increases production. These changes lead increased efficiency CO2 assimilation conditions via regulated specific genes, including RhRbsA. Therefore, may increase tolerance

Although nitrogen (N) is the most limiting nutrient for agricultural production, its overuse associated with environmental pollution, increased concentration of greenhouse gases, and several human animal health implications. These implications are greatly affected by biochemical transformations losses N such as volatilization, leaching, runoff, denitrification. Half globally produced fertilizers used to grow three major cereals—rice, wheat, maize—and their current level recovery approximately 30–50%. The continuously increasing application fertilizers, despite lower cereals, can further intensify leftover N. To address these implications, improvement in use efficiency (NUE) adopting efficient agronomic practices modern breeding biotechnological tools developing cultivars requires immediate attention. Conventional marker-assisted selection methods be map quantitative trait loci, introgression elite germplasm leads creation better NUE. Moreover, gene-editing technology gives opportunity develop high-yielding improved utilization capacity. reliable cheap include site-specific management, enhanced resource conservation practices, precision farming, nano-fertilizers that help farmers reduce from soil–plant system, thus improving Our review illuminates insights into recent advances local scientific soil crop management technologies, along conventional technologies on how increase NUE linked pollution

Most cultivated potatoes are tetraploid, and the tuber is main economic part that consumed due to its calorific nutritional values. Recent trends in climate change led frequent occurrence of heat drought stress major potato-growing regions worldwide. The optimum temperature for production 15–20 °C. High-temperature water-deficient conditions during growing season result several morphological, physiological, biochemical, molecular alterations. morphological changes under may affect process stolon formation, tuberization, bulking, ultimately affecting yield. This condition also affects physiological responses, including an imbalance allocation photoassimilates, respiration, water use efficiency, transpiration, carbon partitioning, source–sink relationship. biochemical responses involve maintaining ionic homeostasis, synthesizing shock proteins, achieving osmolyte balance, generating reactive oxygen species, various pathways. Different networks include both gene regulation transcription factors involved at level combination hot conditions. article attempts present integrative content physio-biochemical combined effects drought, prominent change. Taking into account all these aspects there immediate need comprehensive screening germplasm application appropriate approaches tactics produce potato cultivars perform well heat-affected areas.

Melatonin is a multifunctional molecule that has been widely discovered in most plants. An increasing number of studies have shown melatonin plays essential roles plant growth and stress tolerance. It extensively applied to alleviate the harmful effects abiotic stresses. In view its role regulating aspects development, we ponder summarize scientific discoveries about seed germination, root flowering, fruit maturation, senescence. Under biotic stresses, brings together many pathways increase access treatments for symptoms plants counteract negative effects. capacity tackle regulation redox, hormone networks, endogenous melatonin. Furthermore, expression levels several genes contents diverse secondary metabolites, such as polyphenols, terpenoids, alkaloids, were significantly altered. this review, intend examine actions from broader perspective, explore range physiological functions, analyze relationship between other metabolites metabolic pathways.

Phyto-melatonin improves crop yield by mitigating the negative effects of abiotic stresses on plant growth. Numerous studies are currently being conducted to investigate significant performance melatonin in crops regulating agricultural growth and productivity. However, a comprehensive review pivotal phyto-melatonin morpho-physiological biochemical activities under needs be clarified. This focused research activities, regulation, redox status, signal transduction plants stresses. Furthermore, it also highlighted role defense systems as biostimulants stress conditions. The study revealed that enhances some leaf senescence proteins, protein further interacts with plant’s photosynthesis activity, macromolecules, changes response stress. Our goal is thoroughly evaluate stress, which will help us better understand mechanism regulates yield.

Abstract Melatonin was found in plants the late 1990s, but its function, signaling, and interaction with other phytohormones still unclear. research has increased substantially recent years, including reports on impact of this putative plant hormone under biotic abiotic stress situations. Temperature extremes, salt, drought, hypoxia or anoxia, nutrient deficiency, herbicides, UV radiation stress, heavy metal toxicity are all important obstacles to horticulture crop production worldwide. To deal these environmental challenges, have evolved complex signaling networks. Phytohormones essential for controlling growth, development, responses. Melatonin, a pleiotropic chemical present variety species, recently emerged as powerful regulator tolerance. The purpose review is investigate interplay between melatonin control responses horticultural crops. We explore interactions several various stresses.

Reactive oxygen species (ROS) are important regulating factors that play a dual role in plant and human cells. As the first messenger response organisms, ROS coordinate signals growth, development, metabolic activity pathways. They also can act as an alarm mechanism, triggering cellular responses to harmful stimuli. However, excess cause oxidative stress-related damage oxidize organic substances, leading malfunctions. This review summarizes current research status mechanisms of eukaryotic cells, highlighting differences similarities between two elucidating their interactions with other reactive substances ROS. Based on similar regulatory pathways kingdoms, this proposes future developments provide opportunities develop novel strategies for treating diseases or creating greater agricultural value.

Melatonin is a multifunctional and ubiquitous molecule. In animals, melatonin hormone that involved in wide range of physiological activities also an excellent antioxidant. plants, it has been considered master regulator multiple processes as well hormonal homeostasis. Likewise, known for its role protective biomolecule activator tolerance resistance against biotic abiotic stress plants. Since infections by pathogens such bacteria, fungi viruses crops result large economic losses, interest aroused determining whether plays relevant plant defense systems general, particular. Currently, several strategies have applied to combat infection pathogens, one them the use eco-friendly chemical compounds induce systemic resistance. Few studies addressed biocontrol agent diseases caused viruses. Exogenous treatments used reduce incidence virus diseases, reducing symptoms, titer, even eradicating proliferation Tobacco Mosaic Virus, Apple Stem Grooving Rice Stripe Virus Alfalfa tomato, apple, rice eggplant, respectively.
