Journal of Nanobiotechnology, Год журнала: 2022, Номер 20(1)

Опубликована: Июнь 3, 2022

Abstract Nano-priming is an innovative seed priming technology that helps to improve germination, growth, and yield by providing resistance various stresses in plants. a considerably more effective method compared all other methods. The salient features of nanoparticles (NPs) are develop electron exchange enhanced surface reaction capabilities associated with components plant cells tissues. induces the formation nanopores shoot uptake water absorption, activates reactive oxygen species (ROS)/antioxidant mechanisms seeds, forms hydroxyl radicals loosen walls acts as inducer for rapid hydrolysis starch. It also expression aquaporin genes involved intake mediates H 2 O 2, or ROS, dispersed over biological membranes. starch degradation via stimulation amylase, which results germination. mild ROS primary signaling cue cascade events participate secondary metabolite production stress tolerance. This review provides details on possible nano-priming breaking dormancy, promotion their impact production. In addition, use nano-based fertilizer pesticides materials growth development were discussed, considering recent status future perspectives. Graphical

Reactive oxygen species: Multidimensional regulators of plant adaptation to abiotic stress and development

Journal of Integrative Plant Biology, Год журнала: 2023, Номер 66(3), С. 330 - 367

Опубликована: Дек. 20, 2023

Reactive oxygen species (ROS) are produced as undesirable by-products of metabolism in various cellular compartments, especially response to unfavorable environmental conditions, throughout the life cycle plants. Stress-induced ROS production disrupts normal function and leads oxidative damage. To cope with excessive ROS, plants equipped a sophisticated antioxidative defense system consisting enzymatic non-enzymatic components that scavenge or inhibit their harmful effects on biomolecules. Nonetheless, when maintained at relatively low levels, act signaling molecules regulate plant growth, development, adaptation adverse conditions. Here, we provide an overview current approaches for detecting ROS. We also discuss recent advances understanding signaling, metabolism, roles growth responses abiotic stresses.

How to Cope with the Challenges of Environmental Stresses in the Era of Global Climate Change: An Update on ROS Stave off in Plants

International Journal of Molecular Sciences, Год журнала: 2022, Номер 23(4), С. 1995 - 1995

Опубликована: Фев. 11, 2022

With the advent of human civilization and anthropogenic activities in shade urbanization global climate change, plants are exposed to a complex set abiotic stresses. These stresses affect plants’ growth, development, yield cause enormous crop losses worldwide. In this alarming scenario conditions, respond such through highly balanced finely tuned interaction between signaling molecules. The initiate quick release reactive oxygen species (ROS) as toxic by-products altered aerobic metabolism during different stress conditions at cellular level. ROS includes both free radicals {superoxide (O2•−) hydroxyl (OH−)} well non-radicals [hydrogen peroxide (H2O2) singlet (1O2)]. can be generated scavenged cell organelles cytoplasm depending on type stimulus. At high concentrations, lipid peroxidation, DNA damage, protein oxidation, necrosis, but low moderate they play crucial role secondary messengers intracellular cascades. Because their concentration-dependent dual role, huge number molecules tightly control level cells. have evolved antioxidants scavenging machinery equipped with enzymes maintain equilibrium production detoxification stress. present article, we focused current insights generation Moreover, article will act knowledge base for new pivotal studies scavenging.

Recent Advances in Microbial-Assisted Remediation of Cadmium-Contaminated Soil

Plants, Год журнала: 2023, Номер 12(17), С. 3147 - 3147

Опубликована: Авг. 31, 2023

Soil contamination with cadmium (Cd) is a severe concern for the developing world due to its non-biodegradability and significant potential damage ecosystem associated services. Industries such as mining, manufacturing, building, etc., rapidly produce substantial amount of Cd, posing environmental risks. Cd toxicity in crop plants decreases nutrient water uptake translocation, increases oxidative damage, interferes plant metabolism inhibits morphology physiology. However, various conventional physicochemical approaches are available remove from soil, including chemical reduction, immobilization, stabilization electro-remediation. Nevertheless, these processes costly unfriendly environment because they require much energy, skilled labor hazardous chemicals. In contrasting, contaminated soils can be restored by using bioremediation techniques, which use alone association different beneficial microbes cutting-edge approaches. This review covers new ways. The capability bacteria fungi combination studied analyzed. Microbes, bacteria, algae, reported have high tolerance metals, having 98% capability. internal structure microorganisms, their cell surface characteristics surrounding circumstances all discussed concerning how detoxify metals. Moreover, issues affecting effectiveness explored, along difficulties, solutions prospects.

Field crops are subjected to drought at different growth stages and cause for substantial yield loss in major crops, thus threaten global food security. The crop researcher have evaluated numerous physiological, biochemical molecular strategies combat stresses but these approaches not enough present scenario. Therefore, it is argued that plants can be primed by assorted organic in-organic promoters excelling fortitude under stress conditions. Hence, seed priming with agents an auspicious area of research biology management, conferring tolerance when stress. However, the adaptation mechanisms complex quantitative nature, which been explored levels thoroughly this review. concept memory its implication future generation has also discussed. Finally, review challenges opportunities effective application management along expanding knowledge on deep understanding reduce gap discussed thoroughly.

Impact of Temperature and Water on Seed Germination and Seedling Growth of Maize (Zea mays L.)

Agronomy, Год журнала: 2022, Номер 12(2), С. 397 - 397

Опубликована: Фев. 5, 2022

Germination and seedling development are essential stages in a plant’s life cycle, greatly influenced by temperature moisture conditions. The aim of this study was to determine maize (Zea mays L.) seeds’ germination under various abiotic stresses. Eight different levels, 5, 10, 15, 20, 25, 30, 35, 40 °C, were used. Drought waterlogging stresses tested using 30 water levels based on one-milliliter intervals as percentages thousand kernel weight (TKW) at 20 25 °C. Seedling density the use antifungals also examined. Temperature significantly affected duration growth, °C found be ideal with an optimal range less than occurred 25% TKW. for growth higher broader germination. Seed size assisted defining requirements providing accurate basis. present research established optimum supply 150–325% TKW development. A total 6 seeds per 9 cm Petri dish may preferable over greater densities. technique priming antifungal solution before planting observed have better effect applying it media.
