Sub-Saharan Africa's agricultural sector faces a multifaceted challenge due to climate change consisting of high temperatures, changing precipitation trends, alongside intensified pest and disease outbreaks. Conventional plant breeding methods have historically contributed to yield gains in Africa, and the intensifying demand for food security outpaces these improvements due to a confluence of factors, including rising urbanization, improved living standards, and population growth. To address escalating food demands amidst urbanization, rising living standards, and population growth, a paradigm shift toward more sustainable and innovative crop improvement strategies is imperative. Genome editing technologies offer a promising avenue for achieving sustained yield increases while bolstering resilience against escalating biotic and abiotic stresses associated with climate change. Clustered Regularly Interspaced Short Palindromic Repeats/CRISPR-associated protein (CRISPR/Cas) is unique due to its ubiquity, efficacy, alongside precision, making it a pivotal tool for Sub-Saharan African crop improvement. This review highlights the challenges and explores the prospect of gene editing to secure the region's future foods.
由于气候变化,包括高温、降水趋势变化以及病虫害加剧爆发等因素,撒哈拉以南非洲的农业部门面临着多方面的挑战。传统的植物育种方法在历史上为非洲的产量增长做出了贡献,但由于城市化加速、生活水平提高和人口增长等多种因素的综合作用,对粮食安全的需求日益增长,超过了这些改进。为了解决城市化、生活水平提高和人口增长带来的不断增长的粮食需求,必须转向更加可持续和创新的作物改良策略。基因组编辑技术为实现持续的产量增长提供了一个有前途的途径,同时增强了对与气候变化相关的生物和非生物胁迫的抵御能力。成簇的、规律间隔的短回文重复序列/CRISPR 相关蛋白(CRISPR/Cas)因其普遍性、有效性以及精确性而具有独特性,使其成为撒哈拉以南非洲作物改良的关键工具。本综述重点讨论了该技术所面临的挑战,并探讨了基因编辑在保障该地区未来粮食安全方面的前景。
