The generation of oxygen radicals and their derivatives, known as reactive species, (ROS) is a part the signaling process in higher plants at lower concentrations, but those ROS cause oxidative stress. Salinity-induced osmotic stress ionic trigger overproduction and, ultimately, result damage to cell organelles membrane components, severe levels, they plant death. antioxidant defense system protects from salt-induced by detoxifying also maintaining balance under salt Different hormones genes are associated with protect when exposed Salt-induced overgeneration one major reasons for hampering morpho-physiological biochemical activities which can be largely restored through enhancing that detoxifies ROS. In this review, we discuss ROS, salinity.

Regulation of Reactive Oxygen Species during Salt Stress in Plants and Their Crosstalk with Other Signaling Molecules—Current Perspectives and Future Directions

Plants, Год журнала: 2023, Номер 12(4), С. 864 - 864

Salt stress is a severe type of environmental stress. It adversely affects agricultural production worldwide. The overproduction reactive oxygen species (ROS) the most frequent phenomenon during salt ROS are extremely and, in high amounts, noxious, leading to destructive processes and causing cellular damage. However, at lower concentrations, function as secondary messengers, playing critical role signaling molecules, ensuring regulation growth adjustment multifactorial stresses. Plants contain several enzymatic non-enzymatic antioxidants that can detoxify ROS. their scavenging important aspects plant’s normal response adverse conditions. Recently, this field has attracted immense attention from plant scientists; however, ROS-induced pathways remain largely unknown. In review, we will discuss different tolerance. We also summarize recent advances on detrimental effects ROS, antioxidant machinery under stress, crosstalk between other various including nitric oxide, hydrogen sulfide, calcium, phytohormones. Moreover, utilization “-omic” approaches improve ROS-regulating system adaptation process described.

Global food security for a growing population with finite resources is often challenged by multiple, simultaneously occurring on-farm abiotic stresses (i.e., drought, salinity, low and high temperature, waterlogging, metal toxicity, etc.) due to climatic uncertainties variability. Breeding multiple stress tolerance long-term solution, though developing multiple-stress-tolerant crop varieties still challenge. Generation of reactive oxygen species in plant cells common response under diverse which play dual role signaling molecules or damaging agents depending on concentration. Thus, delicate balance generation may improve health, depends the natural antioxidant defense system plants. Biostimulants represent promising type environment-friendly formulation based products that are frequently used exogenously enhance tolerance. In this review, we illustrate potential biostimulants activity major plants conditions their other roles management stresses. have overcome oxidative stress, wider applicability tightly regulated dose, growth stage, variety biostimulants.

Mechanistic Insights of Plant Growth Promoting Bacteria Mediated Drought and Salt Stress Tolerance in Plants for Sustainable Agriculture

International Journal of Molecular Sciences, Год журнала: 2022, Номер 23(7), С. 3741 - 3741

Опубликована: Март 29, 2022

Climate change has devastating effects on plant growth and yield. During ontogenesis, plants are subjected to a variety of abiotic stresses, including drought salinity, affecting the crop loss (20–50%) making them vulnerable in terms survival. These stresses lead excessive production reactive oxygen species (ROS) that damage nucleic acid, proteins, lipids. Plant growth-promoting bacteria (PGPB) have remarkable capabilities combating salinity stress improving growth, which enhances productivity contributes food security. PGPB inoculation under promotes through several modes actions, such as phytohormones, 1-aminocyclopropane-1-carboxylic acid deaminase, exopolysaccharide, siderophore, hydrogen cyanide, extracellular polymeric substances, volatile organic compounds, modulate antioxidants defense machinery, abscisic thereby preventing oxidative stress. also provide osmotic balance; maintain ion homeostasis; induce salt-responsive genes, metabolic reprogramming, transcriptional changes transporter etc. Therefore, this review, we summarize mitigate its detrimental effects. Furthermore, discuss mechanistic insights towards tolerance for sustainable agriculture.

Cobalt: An Essential Micronutrient for Plant Growth?

Frontiers in Plant Science, Год журнала: 2021, Номер 12

Опубликована: Ноя. 16, 2021

Cobalt is a transition metal located in the fourth row of periodic table and neighbor iron nickel. It has been considered an essential element for prokaryotes, human beings, other mammals, but its essentiality plants remains obscure. In this article, we proposed that cobalt (Co) potentially micronutrient plants. Co growth many lower plants, such as marine algal species including diatoms, chrysophytes, dinoflagellates, well higher family Fabaceae or Leguminosae. The to leguminous attributed role nitrogen (N) fixation by symbiotic microbes, primarily rhizobia. integral component cobalamin vitamin B12, which required several enzymes involved N2 fixation. addition symbiosis, group fixing bacteria known diazotrophs able situate plant tissue endophytes closely associated with roots economically important crops, barley, corn, rice, sugarcane, wheat. Their action provides crops macronutrient N. proteins, participating metabolism. Plants may exhibit deficiency if there severe limitation supply. Conversely, toxic at concentrations. High levels result pale-colored leaves, discolored veins, loss leaves can also cause anticipated advance omics, constitute proteins specific metabolism will be exclusively revealed. confirmation enrich our understanding mineral nutrition improve practice crop production.

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.
