Main conclusion

The review article summarizes the approaches and potential targets to address the challenges of anti-nutrient like phytic acid in millet grains for nutritional improvement.

Abstract

Millets are a diverse group of minor cereal grains that are agriculturally important, nutritionally rich, and the oldest cereals in the human diet. The grains are important for protein, vitamins, macro and micronutrients, fibre, and energy sources. Despite a high amount of nutrients, millet grains also contain anti-nutrients that limit the proper utilization of nutrients and finally affect their dietary quality. Our study aims to outline the genomic information to identify the target areas of research for the exploration of candidate genes for nutritional importance and show the possibilities to address the presence of anti-nutrient (phytic acid) in millets. So, the physicochemical accessibility of micronutrients increases and the agronomic traits can do better. Several strategies have been adopted to minimize the phytic acid, a predominant anti-nutrient in cereal grains. In the present review, we highlight the potential of biotechnological tools and genome editing approaches to address phytic acid in millets. It also highlights the biosynthetic pathway of phytic acid and potential targets for knockout or silencing to achieve low phytic acid content in millets.

降低黍米中植酸含量以提高营养质量的生物技术方法
主要结论这篇综述文章总结了解决小谷物中植酸等抗营养素挑战的方法和潜在目标,以改善营养状况。 摘要小谷物是一组种类繁多的小谷物,具有重要的农业价值,营养丰富,是人类饮食中最古老的谷物。谷物是重要的蛋白质、维生素、宏量和微量营养素、纤维和能量来源。尽管小米含有大量营养素,但它也含有抗营养素,这些抗营养素会限制营养素的正常利用,最终影响其膳食质量。我们的研究旨在概述基因组信息,以确定候选基因对营养重要性的研究目标领域,并展示解决黍子中存在的抗营养素(植酸)问题的可能性。这样,微量营养素的理化可及性就会增加,农艺性状也会更好。为了最大限度地减少谷物中最主要的抗营养素植酸,人们采取了多种策略。在本综述中,我们重点介绍了生物技术工具和基因组编辑方法在解决黍类植酸问题方面的潜力。本综述还强调了植酸的生物合成途径和潜在的基因敲除或沉默靶标,以实现低植酸含量。
