研究组介绍：

本学科组致力于鱼类免疫防控与抗病育种的基础与应用研究，建立高效准确的鱼类基因组编辑育种技术，揭示宿主抗病毒感染的黏膜免疫应答规律，开展鱼类黏膜疫苗及诊断技术研发与储备；二是解析鱼类抗病性状的分子调控机制，培育速生抗病优良品种。相关研究成果发表在主要从两个方面开展工作：一是阐明病毒入侵和复制调控机制，Science Immunology、Cell Discovery、Nature Communications、PNAS、Microbiome、PLOS Pathogens获得星空体育彩票手机版登录自然科学基金、农业生物育种重大项目、星空体育彩票手机版登录先导B专项等项目的支持。等，

主要研究方向：

1）鱼类病毒致病机制与免疫防控技术；

2）鱼类抗病分子遗传机制与育种技术；
