摘要
硒是人类和动物健康必须的微量元素。硒生物强化被认为是向食物链中补充硒的有效途径,硒主要通过膳食摄入进入人体,而十字花科作物普遍具有较强的聚硒能力和硒转化能力,是理想的人体硒膳食补充来源。硒被十字花科作物吸收后,通过不同代谢途径在植物体内迁移和转运,形成硒代蛋氨酸、甲基硒代半胱氨酸等硒代氨基酸。硒与十字花科作物的生长发育存在显著的量效关系,并对其重要营养品质的形成具有重要作用,包括硫代葡萄糖苷、氨基酸、黄酮、多酚等。该文综述了十字花科作物富硒特性及其对硒的吸收和转运,归纳总结了硒与十字花科作物营养品质的相关研究,特别是硫代葡萄糖苷,为培育优质富硒十字花科作物提供参考依据。
Selenium is an essential trace element for human and animal health.Selenium biofortification is considered to be an effective way to supplement selenium for human in the food chain.Selenium enters human body mainly through dietary intake,and curciferous crops generally have strong selenium accumulation and conversion abilities,making them an ideal sources of dietary selenium supplementation for human beings.After selenium is absorbed by cruciferous crops,it migrates and transports through different metabolic pathways in the plant,forming selenomethionine,methylselenocysteine and other selenocysteine amino acids.Selenium has a significant dose-response relationship with the growth and development of cruciferous crops,and plays an important role in the formation of their important nutritional qualities,including glucosinolates,amino acids,flavonoids,polyphenols.This study reviewed the selenium-enriched characteristics of cruciferous crops and their absorption and transportation of selenium.It summarized the relevant studies on selenium and nutritional quality of cruciferous crops,especially glucosinolates,in order to provide reference for the high-quality cultivation of selenium-enriched cruciferous crops.
