Effect of Exogenous Jasmonates on Plant Adaptation to Cold Stress: A Comprehensive Study Based on a Systematic Review with a Focus on Sustainability

In the context of global sustainable development, low-temperature stress is a serious impediment to sustainable agricultural production. Low-temperature stress significantly affects plant growth and development, and Jasmonates (JAs), critical endogenous plant hormones, play a crucial role in cold stress response in plants. Although studies have demonstrated the involvement of JAs in plant adaptation to cold stress, the systematic understanding of its mechanism of action and application effects still needs to be improved. This review used systematic evaluation and meta-analysis to comprehensively review the role of JAs in plant response to cold stress over the past five years. It was found that JA treatment significantly increased plant survival and ascorbate peroxidase (APX) activity while inhibiting primary root growth, malondialdehyde (MDA) content, and catalase (CAT) activity. In particular, JA treatment significantly reduced MDA content when plants were in a solid medium, indicating its role in regulating oxidative stress in plants. In conclusion, this review provides new perspectives for understanding the role of JAs in plant cold stress acclimation and provides a scientific basis for applying JAs in agricultural production.
