Special Issue Information

Dear Colleagues,

Semi-arid and arid areas around the world are subject to a qualitative and quantitative scarcity of water resources. Thus, both scarcity (water deficit) and the occurrence of water sources with high salt concentrations stand out as limiting factors for agricultural production. Thus, there is an urgent need to establish strategies that mitigate abiotic stresses aimed at facilitating the sustainability of crops and meeting growing needs for food production. This Special Issue on Mitigation Strategies and Plant Tolerance to Abiotic Stresses presents original research results on the effects of abiotic stresses, tolerance mechanisms, crop tolerance associated with mitigation strategies, and biomolecular mechanisms. Submitted manuscripts must not be previously published or under evaluation for publication in another journal.

Salt stress can affect various physiological processes in plants, ultimately hindering their growth and development. Melatonin (MT) can effectively resist multiple abiotic stresses, improving plant stress resistance. To analyze the mechanism of exogenous MT to enhance salt tolerance in red clover, we conducted a comprehensive study to examine the influence of exogenous MT on various parameters, including seed germination indices, seedling morphological traits, and physiological and photosynthetic indicators, using four distinct red clover varieties (H1, H2, H3, and H4). This investigation was performed under various salt stress conditions with differing pH values, specifically utilizing NaCl, Na2SO4, NaHCO3, and Na2CO3 as the salt stressors. The results showed that MT solution immersion significantly improved the germination indicators of red clover seeds under salt stress. The foliar spraying of 50 μM and 25 μM MT solution significantly increased SOD activity (21–127%), POD activity, soluble sugar content, proline content (22–117%), chlorophyll content (2–66%), and the net photosynthetic rate. It reduced the MDA content (14–55%) and intercellular CO2 concentration of red clover seedlings under salt stress. Gray correlation analysis and the Mantel test further verified that MT is a key factor in enhancing seed germination and seedling growth of red clover under salt stress; the most significant improvement was observed for NaHCO3 stress. MT is demonstrated to improve the salt tolerance of red clover through a variety of mechanisms, including an increase in antioxidant enzyme activity, osmoregulation ability, and cell membrane stability. Additionally, it improves photosynthetic efficiency and plant architecture, promoting energy production, growth, and optimal resource allocation. These mechanisms function synergistically, enabling red clover to sustain normal growth and development under salt stress. Full article
