Abstract

Banana is an important food security crop for millions of people in the tropics but it faces challenges from diseases and pests. Traditional breeding methods have limitations, prompting the exploration of precision genetic tools like genetic modification and genome editing. Extensive efforts using transgenic approaches have been made to develop improved banana varieties with resistance to banana Xanthomonas wilt, Fusarium wilt, and nematodes. However, these efforts should be extended for other pests, diseases, and abiotic stresses. The commercialization of transgenic crops still faces continuous challenges with regulatory and public acceptance. Genome editing, particularly CRISPR/Cas, offers precise modifications to the banana genome and has been successfully applied in the improvement of banana. Targeting specific genes can contribute to the development of improved banana varieties with enhanced resistance to various biotic and abiotic constraints. This review discusses recent advances in banana improvement achieved through genetic modification and genome editing.

香蕉遗传改良的精密遗传工具。
香蕉是热带地区数百万人重要的粮食保障作物,但它面临着病虫害的挑战。传统的育种方法存在局限性,促使人们探索基因修饰和基因组编辑等精密遗传工具。利用转基因方法开发具有抗黄单胞菌、枯萎病和线虫的改良香蕉品种已经取得了广泛的成果。然而,这些努力应该扩展到其他病虫害和非生物胁迫。转基因作物的商业化仍然面临监管和公众接受的持续挑战。基因组编辑技术,特别是CRISPR/Cas,为香蕉基因组提供了精确的修改,并已成功应用于香蕉的改良。针对特定基因可以促进香蕉品种的改良,增强对各种生物和非生物限制的抗性。本文综述了通过基因修饰和基因组编辑在香蕉改良方面取得的最新进展。
