“…Компонентами цієї мережі є сигнальні посередники (кальцій, активні форми Оксигену (АФО), цАМФ і газотрансмітери -Нітроген оксид, Гідроген сульфід, Карбон монооксид та ін.) (Kolupaev et al, 2022a), деякі стресові метаболіти, зокрема, пролін і поліаміни (Dubrovna et al, 2022;Kolupaev et al, 2022b;Jurkonienė et al, 2023), а також сполуки, що виконують роль медіаторів передачі нервового збудження у тварин; останнім часом їх умовно називають рослинними нейротрансмітерами (мелатонін, серотонін, дофамін, ацетилхолін і γ-аміномасляна кислота) (Akula & Mukherjee, 2020).…”

“…У Vicia faba L. вміст ГАМК знижувався на 30 % за обробки рослин інгібітором діаміноксидази аміногуанідином (Yang et al, 2013), що вказує на участь цього ферменту в синтезі ГАМК із путресцину описаним вище шляхом. Зважаючи на ймовірність утворення 4-амінобутаналю зі спермідину під впливом поліаміноксидази (ПАО -PAO, EC 1.5.3.11) (Kolupaev et al, 2022b), можливий і синтез ГАМК зі спермідину. Також є припущення, що ГАМК може утворюватися з путресцину та проліну неферментативно за умов окиснювального стресу (Signorelli et al, 2015).…”

Ще одним ефектом, важливим для розвитку теплостійкості рослин цього виду за дії ГАМК, може бути зростання вмісту поліамінів (Li et al, 2020b), що розглядаються як мультифункціональні низькомолекулярні протектори і ймовірні джерела сигнальних молекул -Гідроген пероксиду та Нітроген оксиду (Kolupaev et al, 2022b).…”

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

“…polyamines, melatonin, strigolactones, gamma-aminobutyric acid, etc.) have already been recognized as effective for practical application in inducing plant resistance to stress factors, regulating dormancy, and other functions (Sako et al, 2020;Singhal et al, 2021;Kolupaev et al, 2022a;Kosakivska et al, 2022;Raza et al, 2022). On the other hand, the efficiency of practical application of various nitric oxide donors in crop production, primarily as stress-protective agents, has already been shown (Kolupaev et al, 2022b;Khan et al, 2023a;Ullah et al, 2024).…”

This review considers the action of nitric oxide (NO) as a signaling molecule of plant cells, the effects of which can be modulated in crop production practice through the use of nitric oxide donors. The current understanding of nitric oxide synthesis in plants is briefly described. The characterization of synthesized and natural compounds that can be nitric oxide donors is given. The main molecular mechanisms of nitric oxide action in plant cells are characterized: post-translational modification of proteins under the action of NO, its influence on the content of other cellular mediators, in particular, reactive oxygen species and calcium ions. Considerable attention is paid to the functional interaction of nitric oxide with individual phytohormones and new groups of physiologically active substances of plants. Modern ideas on the mechanisms of nitric oxide action on seed germination and plant resistance to adverse abiotic factors are presented. Data on the effects of priming seeds with nitric oxide donors on their germination under optimal and stress conditions are discussed.
