本文综述了大麦黄花叶病(BYMV)抗性基因的染色体定位研究。(1)利用标志基因定位,(2)酯酶同工酶基因位点与抗BYMV基因的关系;(3)应用三体分析进行抗BYMV基因的染色体定位。最后,结合作者的实际工作,提出了基因定位将碰到的问题应用前景。
This article reviews the chromosomal location of the barley yellow mosaic disease (BYMV) resistance gene. (1) the use of marker gene mapping, (2) the relationship between the esterase isozyme locus and resistance to BYMV genes, and (3) the use of trisomic analysis for chromosomal location of BYMV genes. Finally, combined with the author’s actual work, put forward the application prospects of the problems encountered in gene positioning.
