海水养殖鱼类抗病分子育种研究进展及前景展望

PROGRESS IN MOLECULAR BREEDING FOR DISEASE-RESISTANT MARINE FISHES AND ITS PROSPECTS

病害是限制水产养殖业可持续发展的关键因素。而我国目前尚缺乏优良的抗病养殖鱼类品种。鱼类功能基因组和分子标记技术的发展为筛选鱼类抗病相关功能基因和分子标记提供了机遇。基因转移、分子标记和基因标记等分子育种技术是培育抗病优良鱼类新品种的很有潜力的技术手段,已成为国际上的发展趋势,也是我国今后应大力发展的研究领域。本文结合笔者实验室的工作,对某些海水养殖鱼类抗病相关功能基因及抗病分子育种研究的最新进展作一综述介绍。

Disease is key factor restricting sustainable development of fisheries. No fish species with enhanced disease-resistance are available in China.The development of fish functional genomics and molecular marker techniques provides chance for screening functional genes or molecular markers related to disease-resistance. Molecular breeding techniques such as transgenesis, gene marker-assisted selection breeding and molecular marker-assisted selection breeding are potential approaches to developing new strains with enhanced disease-resistance in aquaculture, which should be strengthened in China. The aim of this paper is to provide a survey on the progress in the field of fish disease resistance-related functional genes and molecular breeding.
