摘要
甘薯是重要的粮食、饲料和能源作物,中国是世界上最大的甘薯种植国,甘薯在中国国民经济中占有十分重要的地位。近年来随着气候变化和种薯、种苗地频繁调运,甘薯病害发生日趋严重,新病害不断产生,严重影响甘薯的产量和品质,制约了中国甘薯产业的健康发展。分子生物技术的快速发展给甘薯抗病分子育种研究提供了新的技术支撑和研究思路。本文主要从甘薯抗真菌病、抗细菌病、抗线虫病以及抗病毒病相关基因等方面概述了近年来甘薯抗病相关基因及其功能的研究进展,为甘薯抗病基因的进一步研究和抗病分子育种提供参考。
Sweet potato is an important food,feed and energy crop.China is the world’s largest producer of sweet potato,and sweet potato plays a very important role in China’s national economy.In recent years,with climate change and frequent transportation of sweet potato seedlings,the incidence of sweet potato diseases has become more and more severe and new diseases continue to emerge,seriously affecting the yield and quality of sweet potatoes and restricting the healthy development of China’s sweet potato industry.The rapid development of molecular biotechnology has provided new technical support and research ideas for disease-resistant molecular breeding in sweet potato.This review mainly summarizes the research progress of sweet potato disease resistance-related genes and their functions in recent years from the aspects of anti-fungal,bacterial,nematode and viral disease-related genes.This provides a reference for further research on disease resistance-related genes in sweet potatoes and molecular breeding for disease resistance.
