Among these metabolites, tannins are one of the most abundant polyphenolic compounds, accounting for 25% of the dry weight of leaves, roots and bark of woody plants, but are also abundant in flowering and seed-producing plants. The presence of tannins in these organs serves to protect plants against herbivorous and pathogenic attack through their antidigestive and antimicrobial properties. In addition, tannins play a role in regulating plant growth and development by inhibiting the consumption of unripe fruits due to their astringency. In addition, several studies have also revealed various roles of them under environmental stresses. Tannins can be classified into condensed tannins (CTs), hydrolysable tannins (HTs) and phlorotannins. They are synthesised in plants via the acetate–malonate and shikimic acid pathways. Their accumulation is regulated by several transcription factors during normal development and under different stress conditions. Despite their multiple roles in plant life, information on the regulation of tannin metabolism by defence-related phytohormones is very limited. To cope with biotic and abiotic stresses, plant responses are regulated by defence-related phytohormones such as salicylic acid (SA), jasmonic acid (JA), ethylene (ET) and abscisic acid (ABA), which act as regulators of tannin production under adverse conditions. This review focuses on tannin production, moreover its occurrence, defence potential and regulation by phytohormones under different environmental and biotic stresses, based on the most recent and relevant data.}, year = {2024}, eissn = {1435-8107}, orcid-numbers = {Poór, Péter/0000-0002-4539-6358} } @article{MTMT:34479762, title = {Plant hormone ethylene: A leading edge in conferring drought stress tolerance}, url = {https://m2.mtmt.hu/api/publication/34479762}, author = {Nazir, Faroza and Poór, Péter and Gupta, Ravi and Kumari, Sarika and Nawaz, Kashif and Khan, M.

Climatic abruptions have been emerging as one of the most nerve‐pressing issues for the sustainment of the planet Earth in the twenty‐first century. Among the various environmental constraints, drought stress stands out as a potent factor restricting crop growth and productivity. It triggers a myriad of intricate responses in plants to combat the underlying stress‐mediated adversities. Gaining a comprehensive understanding of the key physiological and molecular mechanisms that enable plants to withstand drought stress is crucial for developing effective strategies to enhance crop resilience. Ethylene, a gaseous plant hormone, influences the adaptive measures adopted by plants subjected to drought stress by regulating the drought stress‐mediated signal transduction‐associated responses. The present review article provides an in‐depth understanding of the critical roles of ethylene in enhancing plants' ability to restrain the severity of drought stress. It also highlights the significance of ethylene signaling components in regulating plant survival and drought stress tolerance. Additionally, we have illustrated the additive and antagonistic interactions of ethylene with other plant growth regulators, which instigate the tolerance responses. Conclusively, this review emphasizes the significance of complex networks involved in ethylene‐mediated drought tolerance, providing valuable insights for future research and uncovering novel studies in the field of ethylene biology.}, year = {2024}, eissn = {1399-3054}, orcid-numbers = {Poór, Péter/0000-0002-4539-6358; Gupta, Ravi/0000-0001-5242-9528; Khan, M.

Fusarium species produce FA as a secondary metabolite, which can infect many agronomic crops at all stages of development from seed to fruit, and FA production can further compromise plant survival because of its phytotoxic effects. FA exposure in plant species adversely affects plant growth, development and crop yield. FA exposure in plants leads to the generation of reactive oxygen species (ROS), which cause cellular damage and ultimately cell death. Therefore, FA-induced ROS accumulation in plants has been a topic of interest for many researchers to understand the plant–pathogen interactions and plant defence responses. In this study, we reviewed the FA-mediated oxidative stress and ROS-induced defence responses of antioxidants, as well as hormonal signalling in plants. The effects of FA phytotoxicity on lipid peroxidation, physiological changes and ultrastructural changes at cellular and subcellular levels were reported. Additionally, DNA damage, cell death and adverse effects on photosynthesis have been explained. Some possible approaches to overcome the harmful effects of FA in plants were also discussed. It is concluded that FA-induced ROS affect the enzymatic and non-enzymatic antioxidant system regulated by phytohormones. The effects of FA are also associated with other photosynthetic, ultrastructural and genotoxic modifications in plants.}, year = {2024}, eissn = {1432-203X}, orcid-numbers = {Ördög, Attila/0000-0002-1867-8237; Poór, Péter/0000-0002-4539-6358} } @article{MTMT:34397467, title = {The role of salicylic acid on glutathione metabolism under endoplasmic reticulum stress in tomato}, url = {https://m2.mtmt.hu/api/publication/34397467}, author = {Czékus, Zalán and Milodanovic, Dávid and Koprivanacz, Péter and Bela, Krisztina and López-Climent, María F. and Gómez-Cadenas, Aurelio and Poór, Péter}, doi = {10.1016/j.plaphy.2023.108192}, journal-iso = {PLANT PHYSIOL BIOCH (PPB)}, journal = {PLANT PHYSIOLOGY AND BIOCHEMISTRY}, volume = {205}, unique-id = {34397467}, issn = {0981-9428}, year = {2023}, eissn = {1873-2690}, orcid-numbers = {Bela, Krisztina/0000-0003-0124-4552; López-Climent, María F./0000-0001-9307-0128; Gómez-Cadenas, Aurelio/0000-0002-4598-2664; Poór, Péter/0000-0002-4539-6358} } @{MTMT:34392614, title = {The role of nitric oxide in systemic responses of plants}, url = {https://m2.mtmt.hu/api/publication/34392614}, author = {Czékus, Zalán and Poór, Péter}, booktitle = {Nitric Oxide in Developing Plant Stress Resilience}, doi = {10.1016/B978-0-323-91209-9.00004-X}, unique-id = {34392614}, abstract = {Plants are exposed to various biotic stressors during their life which often leads to a localized cell death termed as hypersensitive response (HR) and induces systemic responses in their distal organs from the infected ones which often promotes the development of systemic acquired resistance (SAR) against secondary pathogen infection.
