Genomics-assisted breeding represents a crucial frontier in enhancing the balance between sustainable agriculture, environmental preservation, and global food security. Its precision and efficiency hold the promise of developing resilient crops, reducing resource utilization, and safeguarding biodiversity, ultimately fostering a more sustainable and secure food production system. Agriculture has been seriously threatened over the last 40 years by climate changes that menace global nutrition and food security. Changes in environmental factors like drought, salt concentration, heavy rainfalls, and extremely low or high temperatures can have a detrimental effects on plant development, growth, and yield. Extreme poverty and increasing food demand necessitate the need to break the existing production barriers in several crops. The first decade of twenty-first century marks the rapid development in the discovery of new plant breeding technologies. In contrast, in the second decade, the focus turned to extracting information from massive genomic frameworks, speculating gene-to-phenotype associations, and producing resilient crops. In this review, we will encompass the causes, effects of abiotic stresses and how they can be addressed using plant breeding technologies. Both conventional and modern breeding technologies will be highlighted. Moreover, the challenges like the commercialization of biotechnological products faced by proponents and developers will also be accentuated. The crux of this review is to mention the available breeding technologies that can deliver crops with high nutrition and climate resilience for sustainable agriculture.
基因组辅助育种代表了在可持续农业、环境保护和全球粮食安全之间取得平衡的重要前沿领域。其精确性和效率有望培育出具有弹性的作物,减少资源利用,并保护生物多样性,最终构建出更可持续和安全的粮食生产体系。
在过去的 40 年里,气候变化严重威胁到农业,危及全球营养和粮食安全。环境因素的变化,如干旱、盐浓度、暴雨以及极低或极高的温度,都会对植物的发育、生长和产量产生不利影响。极端贫困和不断增长的粮食需求要求我们在几种作物中打破现有的生产障碍。二十一世纪的头十年见证了新植物育种技术的快速发展。相比之下,在第二个十年,重点转向从大量基因组框架中提取信息,推测基因与表型的关联,并培育具有弹性的作物。
在这篇综述中,我们将涵盖非生物胁迫的原因、影响以及如何利用植物育种技术来解决这些问题。我们将重点介绍传统和现代的育种技术。此外,还将强调支持者和开发者在生物技术产品商业化方面面临的挑战。
这篇综述的核心是要提到现有的一些育种技术,这些技术可以为可持续农业生产提供具有高营养价值和气候弹性的作物。
