摘要
图位克隆(Map-based cloning)作为分离基因的有效方法,已在小基因组作物的基因分离中得到了广泛应用和发展,而在具有大量重复DNA序列的大基因组作物中的应用仍存在挑战。基于图位克隆在基因分离中的重要性,文章就图位克隆技术的基本内容及发展做简要概述,着重对图位克隆技术在大基因组作物中的应用进行分析和评价,同时对它今后可能的发展方向进行了讨论,以期为大基因组作物基因的分离提供借鉴。
As an efficient strategy for gene isolation, map-based cloning has been widely applied and well advanced in crops with small genomes. However, the application of this strategy is challenging in crops with large genomes that are rich in repetitive DNA. Because of the importance of map-based cloning, its basic contents and development are summarized. In particular, the application of this strategy is analyzed and evaluated in large genome crops, and the potential directions of its development are discussed. These help to promote genes cloning in large genome crops.
