Leveraging advanced breeding and multi-omics resources is vital to position millet as an essential "nutricereal resource," aligning with IYoM goals, alleviating strain on global cereal production, boosting resilience to climate change, and advancing sustainable crop improvement and biodiversity. The global challenges of food security, nutrition, climate change, and agrarian sustainability demand the adoption of climate-resilient, nutrient-rich crops to support a growing population amidst shifting environmental conditions. Millets, also referred to as "Shree Anna," emerge as a promising solution to address these issues by bolstering food production, improving nutrient security, and fostering biodiversity conservation. Their resilience to harsh environments, nutritional density, cultural significance, and potential to enhance dietary quality index made them valuable assets in global agriculture. Recognizing their pivotal role, the United Nations designated 2023 as the "International Year of Millets (IYoM 2023)," emphasizing their contribution to climate-resilient agriculture and nutritional enhancement. Scientific progress has invigorated efforts to enhance millet production through genetic and genomic interventions, yielding a wealth of advanced molecular breeding technologies and multi-omics resources. These advancements offer opportunities to tackle prevailing challenges in millet, such as anti-nutritional factors, sensory acceptability issues, toxin contamination, and ancillary crop improvements. This review provides a comprehensive overview of molecular breeding and multi-omics resources for nine major millet species, focusing on their potential impact within the framework of IYoM. These resources include whole and pan-genome, elucidating adaptive responses to abiotic stressors, organelle-based studies revealing evolutionary resilience, markers linked to desirable traits for efficient breeding, QTL analysis facilitating trait selection, functional gene discovery for biotechnological interventions, regulatory ncRNAs for trait modulation, web-based platforms for stakeholder communication, tissue culture techniques for genetic modification, and integrated omics approaches enabled by precise application of CRISPR/Cas9 technology. Aligning these resources with the seven thematic areas outlined by IYoM catalyzes transformative changes in millet production and utilization, thereby contributing to global food security, sustainable agriculture, and enhanced nutritional consequences.
利用先进的育种和多组学资源对于将小米定位为重要的“营养谷物资源”至关重要,这与 IYoM 的目标一致,可缓解全球谷物生产的压力,提高对气候变化的适应能力,推进可持续作物改良和生物多样性。粮食安全、营养、气候变化和农业可持续性的全球挑战需要采用具有抗逆能力、营养丰富的作物,以在环境条件变化的情况下支持不断增长的人口。小米,也被称为“Shree Anna”,作为解决这些问题的一种有前途的解决方案出现,通过增加粮食生产、改善营养安全和促进生物多样性保护来应对这些问题。它们对恶劣环境的适应能力、营养密度、文化意义以及提高膳食质量指数的潜力,使它们成为全球农业的宝贵资产。联合国认识到它们的关键作用,将 2023 年指定为“国际小米年(IYoM 2023)”,强调它们对气候适应型农业和营养增强的贡献。科学的进步激发了通过遗传和基因组干预来提高小米产量的努力,产生了丰富的先进分子育种技术和多组学资源。这些进展为解决小米面临的普遍挑战提供了机会,例如抗营养因子、感官可接受性问题、毒素污染和辅助作物改良。本综述全面概述了用于九种主要小米物种的分子育种和多组学资源,重点介绍了它们在 IYoM 框架内的潜在影响。这些资源包括全基因组和泛基因组,阐明了对非生物胁迫的适应性反应;基于细胞器的研究揭示了进化适应能力;与高效育种相关的有利性状标记;用于性状选择的 QTL 分析;用于生物技术干预的功能基因发现;用于性状调节的调控 ncRNA;用于利益相关者沟通的基于网络的平台;用于遗传修饰的组织培养技术;以及通过精确应用 CRISPR/Cas9 技术实现的综合组学方法。将这些资源与 IYoM 概述的七个主题领域相结合,可以促进小米生产和利用的变革性变化,从而为全球粮食安全、可持续农业和增强的营养结果做出贡献。
