Abstract

Phytohormones are the key regulators of plant growth, development, and responses to environmental stressors. Among these, jasmonates (JAs) are particularly crucial, derived mainly from α-linolenic acid (α-LA). JAs govern various physiological processes like seed germination, root elongation, and apical hook formation, while also influencing secondary metabolite production and defense mechanisms. Interacting with enzymes, genes, and other growth regulators, JAs modulate intricate signaling pathways, activating metabolic responses in both normal and stressed conditions. Transcription factors such as MYB, WRKY, basic Helix-Loop-Helix (bHLH), and APETALA2/JA-responsive ethylene response factor (AP2/ERF) are central components to JA signaling pathways, impacting the synthesis of bioactive compounds of therapeutic potential. Additionally, JAs act as chemical elicitors, promoting secondary metabolite production in vitro, leveraging advancements in plant cell and tissue culture techniques. In this regard, the present review offers a comprehensive discussion on diverse roles of JAs in plant physiology and biochemistry, including its biosynthesis, and suggests strategies for large-scale bioactive compound production via plant cell and tissue culture methods.

茉莉酸：一种调节生长、生理和生化反应的多功能植物激素

植物激素是植物生长、发育和应对环境胁迫的关键调节因子。其中，茉莉酸盐（JAs）尤为重要，主要来源于α-亚麻酸（α-LA）。JAs 主导着各种生理过程，如种子萌发、根系伸长和顶端钩的形成，同时还影响次生代谢物的产生和防御机制。JAs 与酶、基因和其他生长调节剂相互作用，调节复杂的信号通路，激活正常和受压条件下的代谢反应。转录因子（如 MYB、WRKY、基本螺旋-环-螺旋（bHLH）和 APETALA2/JA-反应性乙烯反应因子（AP2/ERF））是 JA 信号通路的核心成分，影响着具有治疗潜力的生物活性化合物的合成。此外，JA 还可作为化学诱导剂，利用植物细胞和组织培养技术的进步，在体外促进次生代谢产物的产生。在这方面，本综述全面讨论了 JAs 在植物生理和生物化学中的各种作用，包括其生物合成，并提出了通过植物细胞和组织培养方法大规模生产生物活性化合物的策略。

期刊介绍： The Journal of Plant Growth Regulation is an international publication featuring original articles on all aspects of plant growth and development. We welcome manuscripts reporting question-based research on various aspects of plant growth and development using hormonal, physiological, environmental, genetic, biophysical, developmental and/or molecular approaches. The journal also publishes timely reviews on highly relevant areas and/or studies in plant growth and development, including interdisciplinary work with an emphasis on plant growth, plant hormones and plant pathology or abiotic stress. In addition, the journal features occasional thematic issues with special guest editors, as well as brief communications describing novel techniques and meeting reports. The journal is unlikely to accept manuscripts that are purely descriptive in nature or reports work with simple tissue culture without attempting to investigate the underlying mechanisms of plant growth regulation, those that focus exclusively on microbial communities, or deal with the (elicitation by plant hormones of) synthesis of secondary metabolites.
