Abstract

Global challenges and new demands require adaptation of cropping systems. Plant genetic diversity can contribute to adapt and improve crops and create more sustainable agricultural systems. In order to harness this diversity, a unified framework that combines genomic, ecological, and geographical approaches is needed for targeted conservation efforts and breeding strategies. In this review, we discuss the potential of genetic diversity to improve the nutritious and resilient pseudocereal grain amaranth. We emphasize on the utilization of within crop diversity and crop wild relatives. We discuss the impact of hybridization and introgression in facilitating the exchange of genetic material between wild and cultivated amaranth, highlighting their significance in broadening the crop's genetic base. Additionally, we focus on utilization of climate distribution models in predicting the future geographic ranges and their suitability with implications for conservation and future sustainability. We aim to suggest a roadmap for leveraging genetic diversity of underutilized crops to contribute to resilient and sustainable cropping systems in a changing climate.

可持续种植系统中苋菜多样性的评估与挖掘。

全球挑战和新的需求要求调整种植制度。植物遗传多样性有助于适应和改善作物，并创造更可持续的农业系统。为了利用这种多样性，需要一个结合基因组、生态和地理方法的统一框架，以进行有针对性的保护工作和育种策略。在这篇综述中，我们讨论了遗传多样性在提高苋菜营养和抗逆性方面的潜力。重点介绍了作物多样性和作物野生近缘种质资源的利用。我们讨论了杂交和渗渗在促进野生和栽培苋菜之间遗传物质交换方面的影响，强调了它们在扩大作物遗传基础方面的重要意义。此外，我们还关注了气候分布模型在预测未来地理范围及其对保护和未来可持续性的影响方面的应用。我们的目标是提出一个路线图，以利用未充分利用的作物的遗传多样性，在不断变化的气候下促进有弹性和可持续的种植系统。

期刊介绍： Theoretical and Applied Genetics publishes original research and review articles in all key areas of modern plant genetics, plant genomics and plant biotechnology. All work needs to have a clear genetic component and significant impact on plant breeding. Theoretical considerations are only accepted in combination with new experimental data and/or if they indicate a relevant application in plant genetics or breeding. Emphasizing the practical, the journal focuses on research into leading crop plants and articles presenting innovative approaches.
