Cassava is an important staple food crop for millions of people in tropical regions across Africa, South America and Asia. Viral, bacterial and fungal diseases impact cassava yield in all three regions. The viruses causing cassava mosaic disease and cassava brown streak disease have been particularly devastating to cassava production in Africa. Improved farming practices and disease monitoring can reduce the impact of cassava diseases in the field. The availability of disease resistant cassava varieties developed through breeding or genetic engineering is key to tackling disease incidence and severity.
木薯是非洲、南美洲和亚洲热带地区数百万人的重要主食作物。病毒、细菌和真菌病害影响着这三个地区的木薯产量。导致木薯花叶病和木薯褐色条纹病的病毒对非洲的木薯生产造成了特别严重的破坏。改进种植方法和病害监测可以减少田间木薯病害的影响。通过育种或基因工程培育出抗病木薯品种是应对病害发生率和严重程度的关键。
