Abstract In recent years, there has been an increase in the study of phytomelatonin. Having numerous functions animals, melatonin produced by plants (phytomelatonin) is also a multi‐regulatory molecule with great potential plant physiology and mitigating abiotic stresses, such as drought, salinity, chilling, heat, chemical contamination, UV‐radiation stress. This review highlights primary phytomelatonin anti‐stress against We discuss role master regulator, oxidative stress manager, reactive oxygen species nitrogen defense compounds inducer. Although exist handful reviews on crosstalk other signaling molecules like auxin, cytokinin, gibberellin, abscisic acid, ethylene, nitric oxide, jasmonic salicylic this looks at studies that have reported few aspects newly discovered along classical relation to tolerance. The research applications hydrogen sulfide, strigolactones, brassinosteroids, polyamines are still their nascent stage but hold promising scope for future. Additionally, states developments metabolism nitrosative plants.

Effects of exogenous SLs on growth and physiological characteristics of flue-cured tobacco seedlings under different degrees of drought stress

Frontiers in Plant Science, Journal Year: 2025, Volume and Issue: 15

Published: Jan. 20, 2025

Background Drought stress severely affects global crop yields, reduces water availability, and hinders growth. Strigolactones can alleviate damage caused by various abiotic stresses in plants; however, limited research has been conducted on their ability to enhance drought tolerance tobacco. Methods This study evaluated the of ‘Qin Tobacco 96’ (drought-tolerant) ‘Yun 116’ (moisture-sensitive) before after application gibberellic acid lactone at a concentration 0.2 mg·L⁻¹ under three conditions: mild, moderate, severe. The primary traits were identified from 29 related indicators, including agronomic traits, photosynthetic efficiency, reactive oxygen metabolism, antioxidant enzyme activities, osmotic regulators, hormone regulation, using affiliation function, principal component analysis, cluster analysis categorize traits. degree enhancement two tobacco varieties was treatments. Results Spraying exogenous strigolactones reduced adverse effects stress, particularly moisture-sensitive Y116 variety. Under chlorophyll content parameters significantly decreased, whereas strigolactone treatment increased both efficiency. accumulation species malondialdehyde content, enhancing capacity varieties. Additionally, levels osmoregulatory substances activated production enzymes, thereby tolerance. Furthermore, disrupted balance endogenous hormones, decreasing auxin, acid, ribosylzeatin, while increasing abscisic levels. Exogenous restored this hormonal balance. Conclusion Sixteen associated with analyzed classified magnitude D-value determined calculating values function respective weights. results indicated that enhanced across different promoted growth development flue-cured However, interactions between hormones require further investigation elucidate underlying molecular mechanisms. methods should be optimized.
