An Overview on Molecular Biology of Flax(Linum usitatissimum L.) in China

我国亚麻分子生物学研究概述（英文）

The advances in molecular biology research of flax （Linum usitatissimum L.）, including DNA extraction, gene cloning and transformation, molecular markers, molecular identity, genetic diversity analysis, construction of genetic linkage map etc. were summarized in this article. Meanwhile, some problems existing in flax breeding, cultivation and germplasm classification were pointed out, including less developed molecular markers, lack of target genes and usable markers, genetic linkage map covering less genome, less research on molecular biology and so on. Five constructive suggestions were finally proposed in this article to provide reference for molecular biology research and development of Chinese flax.

为了促进中国亚麻分子生物学研究的发展,该文总结了中国亚麻DNA提取、基因克隆与转化、分子标记、分子身份证、遗传多样性分析、遗传图谱构建等方面的研究进展,并提出上述各方面存在的分子标记开发较少,目的基因及可用的性状标记缺乏,分子遗传图谱覆盖基因组范围较小,有关栽培的分子生物学方面的研究比较少,满足不了育种、栽培以及种质资源分类等相关研究要求等一系列问题。针对存在的问题提出了5点建设性建议,以期为中国亚麻分子生物学研究与发展提供参考。
