Global warming causes heat and drought stress in plants, which affects crop production. In addition to osmotic protein inactivation, reactive oxygen species (ROS) overaccumulation under is a secondary that further impairs plant performance. Chloroplasts, mitochondria, peroxisomes, apoplasts are the main ROS generation sites heat- drought-stressed plants. this review, we summarize scavenging plants highlight potential applications of nanobiotechnology for enhancing tolerance these stresses.

Adaptation of plants to stress factors occurs with the participation phytohormones, signaling network and plant neurotransmitters. Among latter, in particular, γ-aminobutyric acid (γ-aminobutyric – GABA) is a non-proteinogenic four-carbon amino found many prokaryotic eukaryotic organisms. Its functions have been actively studied only past decade. During this period, lot information has accumulated about protective effect exogenous GABA on various taxonomic groups under influence nature. The first national review devoted analysis generalization data mechanisms stress-protective action plants. ways synthesis metabolism cells activation these processes stressful conditions are described. It noted that main way formation decarboxylation glutamate by means decarboxylase. Possible reception signal transmission genetic apparatus discussed. Special attention paid new role calcium realization its physiological effects. GABA’s functioning mitochondria, maintaining redox homeostasis At same time, increase expression genes encoding catalytic subunit NADPH oxidase presented. Functional connections between nitric oxide as mediator considered. reactions characterized: state antioxidant system, accumulation multifunctional low-molecular protectors, dehydrins chaperones. phenomenology effects abiotic stresses presented: extreme temperatures, drought salinity prospects for practical use compound combines an energy metabolite noted.

Plants are directly exposed to several biotic factors. Among these, mite species belonging the superfamilies Eriophyoidea and Tetranychoidea stand out due their ability injure or even transmit viruses host plants. In response infestations by these organisms, reactive oxygen (ROS), regulated enzymatic non-enzymatic antioxidants (homeostasis), can act as signaling molecules induce defenses acclimatization in attacked However, depending on severity of stress, there be an imbalance between ROS that result oxidative leading membrane damage lipid peroxidation, organelle inactivation, cell death. this review, we outline for first time current state understanding regarding role cellular processes metabolism, such signaling, potential induced ROS, defense antioxidant systems involved plant–mite relationship. Furthermore, identify gaps redox metabolism plant against phytophagous mites.

Oxidative stress is an important component of heat- and drought-induced damage in plants. However, information on the relationship between resistance cultivated plants with different genotypes to environmental factors their ability maintain a pro-/antioxidant balance remains contradictory. This study aimed compare growth responses adaptation antioxidant system wheat cultivars oxidative agents hydrogen peroxide iron(II) sulfate. Etiolated seedlings common winter (Triticum aestivum L.) Antonivka Tobak (heat- drought-tolerant), Avgustina Doskonala (not resistant heat drought) were used for study. Three-day-old etiolated exposed 50 mM H2O2 or 5 FeSO4 one day. It was found that treated able relatively intensive growth, accumulated significantly lower amounts endogenous lipid peroxidation products, increased anthocyanin content had higher activity SOD catalase as compared non-resistant cultivars. The non-tolerant cultivars’ response only increase proline simultaneous decrease anthocyanins content. identified varietal markers adaptive strategy can be develop new approaches screening cross-resistance major abiotic stressors.

The stress-protective effects of plant neurotransmitters, including gamma-aminobutyric acid (GABA) have been intensively examined in recent years. However, studies on the GABA influence stress protective systems bread wheat cultivars with different drought adaptation strategies are still lacking. aim this work was to estimate effect state antioxidant and osmoprotective etiolated seedlings two differing significantly tolerance, namely Doskonala (non-drought-resistant) Tobak (drought-resistant) under model induced by PEG 6000. Two-day-old were transferred 15% 6000 incubated for days absence or presence GABA. Treatment 0.1 0.5 mM reduced growth-inhibitory roots shoots both cultivars, but a greater extent those non-resistant Doskonala. It shown that treatment drought-induced accumulation H2O2 MDA, stabilized SOD GPX activity, level sugars, anthocyanins flavonoids cultivars. Meanwhile enhanced stress-induced increase proline content cultivar, decreased it Tobak, completely prevented decrease only partially cultivar. Thus, stabilization functioning variety-dependent differences response revealed. Keywords: anthocyanins, system, resistance, acid, oxidative stress, proline, Triticum aestivum

Melatonin is a multifunctional molecule whose biological activity has been intensively studied in recent years the context of plant adaptation to abiotic stresses, including drought.However, comprehensive studies on effect melatonin status antioxidant and osmoprotective systems wheat varieties with different drought strategies have lacking.We growth functioning stress protection (Triticum aestivum L.) seedlings Tobak (drought-tolerant) Doskonala (drought-sensitive) varieties.Two-day-old etiolated were transferred 15% PEG 6000 solution for 2 days create model drought.The addition incubation medium at concentrations range 0.2-5.0μM significantly alleviated inhibition root shoot caused by effects more pronounced drought-sensitive cultivar Doskonala.Melatonin treatment almost completely eliminated increased hydrogen peroxide content under conditions both varieties.Also variety, reduced stress-induced accumulation lipid peroxidation products.Drought decrease superoxide dismutase varieties, while helped maintain enzyme level close that control variants.In also reversed guaiacol peroxidase activity.Under
