硫代葡萄糖苷是一类次生代谢产物，主要存在于十字花科植物中，受环境变化的影响。本综述重点关注硫代葡萄糖苷及其水解产物在植物应对不同非生物胁迫中的生理意义。特别关注了胁迫响应所涉及的一些生理过程与硫代葡萄糖苷代谢之间的相互作用，以及这两种途径之间由此产生的联系，在这些联系中硫代葡萄糖苷可能自身作为信号发挥作用。除了在防御转换中的作用外，还从在非生物胁迫下缓解病原体侵袭的角度讨论了硫代葡萄糖苷的功能。根据最近的报道，描述了硫代葡萄糖苷水解产物的外源添加可能通过其对特定蛋白质的作用来缓解某些胁迫条件这一事实，但这种响应所涉及的分子机制值得进一步研究。最后，总结了硫代葡萄糖苷作为对环境变化的响应的瞬时分配和再分配。
Glucosinolates, a class of secondary metabolites, mainly found in Brassicaceae, are affected by the changing environment. This review is focusing on the physiological significance of glucosinolates and their hydrolysis products in the plant response to different abiotic stresses. Special attention is paid to the crosstalk between some of the physiological processes involved in stress response and glucosinolate metabolism, with the resulting connection between both pathways in which signaling mechanisms glucosinolate may act as signals themselves. The function of glucosinolates, further than in defense switching, is discussed in terms of alleviating pathogen attack under abiotic stress. The fact that the exogenous addition of glucosinolate hydrolysis products may alleviate certain stress conditions through its effect on specific proteins is described in light of the recent reports, but the molecular mechanisms involved in this response merit further research. Finally, the transient allocation and re-distribution of glucosinolates as a response to environmental changes is summarized.
