Biofortification is a revolutionary technique for improving plant nutrition and alleviating human micronutrient deficiency. Fertilizers can help increase crop yield and growth, but applying too much fertilizer can be a problem because it leads to the release of greenhouse gases and eutrophication. One of the major global hazards that affects more than two million people globally is the decreased availability of micronutrients in food crops, which results in micronutrient deficiencies or "hidden hunger" in people. Micronutrients, like macronutrients, perform a variety of roles in plant and human nutrition. This review has highlighted the importance of micronutrients as well as their advantages. The uneven distribution of micronutrients in geological areas is not the only factor responsible for micronutrient deficiencies, other parameters including soil moisture, temperature, texture of the soil, and soil pH significantly affects the micronutrient concentration and their availability in the soil. To overcome this, different biofortification approaches are assessed in the review in which microbes mediated, Agronomic approaches, Plant breeding, and transgenic approaches are discussed. Hidden hunger can result in risky health conditions and diseases such as cancer, cardiovascular disease, osteoporosis, neurological disorders, and many more. Microbes-mediated biofortification is a novel and promising solution for the bioavailability of nutrients to plants in order to address these problems. Biofortification is cost effective, feasible, and environmentally sustainable. Bio-fortified crops boost our immunity, which helps us to combat these deadly viruses. The studies we discussed in this review have demonstrated that they can aid in the alleviation of hidden hunger.
生物强化是一种革命性的技术,可以改善植物的营养状况,缓解人类的微量营养素缺乏症。肥料可以帮助增加作物的产量和生长,但施用过多的肥料可能会成为一个问题,因为它会导致温室气体的释放和富营养化。全球主要的危害之一是粮食作物中微量营养素的可用性降低,这导致人们出现微量营养素缺乏或“隐性饥饿”。微量营养素与宏量营养素一样,在植物和人类营养中发挥着多种作用。这篇综述强调了微量营养素的重要性及其优势。地质区域中微量营养素分布不均并不是导致微量营养素缺乏的唯一因素,其他参数包括土壤水分、温度、土壤质地和土壤 pH 值,都会显著影响土壤中微量营养素的浓度及其可用性。为了克服这一问题,本综述评估了不同的生物强化方法,其中讨论了微生物介导、农业方法、植物育种和转基因方法。隐性饥饿会导致危险的健康状况和疾病,如癌症、心血管疾病、骨质疏松症、神经紊乱等。微生物介导的生物强化是一种新颖且有前途的方法,可以提高植物对营养物质的生物利用度,以解决这些问题。生物强化具有成本效益、可行性和环境可持续性。生物强化作物增强了我们的免疫力,有助于我们对抗这些致命病毒。我们在本综述中讨论的研究表明,它们可以帮助缓解隐性饥饿。
