Micronutrient deficiency in the human body, popularly known as "hidden hunger", causes many health problems. It presently affects >2 billion people worldwide, especially in South Asia and sub-Saharan Africa. Biofortification of food crop varieties is one way to combat the problem of hidden hunger using conventional plant breeding and transgenic methods. Lentils are rich sources of protein, micronutrients, and vitamins including iron, zinc, selenium, folates, and carotenoids. Lentil genetic resources including germplasm and wild species showed genetic variability for these traits. Studies revealed that a single serving of lentils could provide a significant amount of the recommended daily allowance of micronutrients and vitamins for adults. Therefore, lentils have been identified as a food legume for biofortification, which could provide a whole food solution to the global micronutrient malnutrition. The present review discusses the current ongoing efforts toward genetic biofortification in lentils using classical breeding and molecular marker-assisted approaches.
人体中的微量营养素缺乏，俗称“隐性饥饿”，会引发许多健康问题。目前，全球有超过20亿人受其影响，尤其是在南亚和撒哈拉以南非洲地区。利用传统植物育种和转基因方法对粮食作物品种进行生物强化，是解决隐性饥饿问题的一种途径。小扁豆富含蛋白质、微量营养素和维生素，包括铁、锌、硒、叶酸和类胡萝卜素。包括种质和野生种在内的小扁豆遗传资源在这些性状上表现出遗传变异性。研究表明，一份小扁豆可为成年人提供大量建议每日摄入量的微量营养素和维生素。因此，小扁豆已被确定为用于生物强化的食用豆类，可为全球微量营养素营养不良问题提供全食物解决方案。本综述讨论了目前利用经典育种和分子标记辅助方法对小扁豆进行基因生物强化的努力。
