Gl~e_2 是在棉花植物和种子控制腺更少特点的变异的基因。它是到 gossypol 免费的棉子繁殖的一个重要基因资源。这研究的目的是开发使用包含从 G 的十字导出的 1599 植物的 F_2segregating 人口紧与 Gil 连接的 SSR 标记。hirsutum 基因标准线 TM-1 和 G。barbadense 腺更少异种线 Hai-1。基因分析建议 Gl~e_2 是不完全的主导的基因。从 G 基于基因连接地图的脊梁。hirsutum x G。barbadense BC_1 由我们的实验室出版了, Gl~e_2 在 CIR362 和 NAU2251b 之间被定位, NAU3860b, STV033,与基因距离 9.27 和 0.96 厘米分别地。这结果为由基于地图的克隆的方法克隆 Gl~e_2 基因是有用的。
Gl2^e is a mutant gene that controls glandless trait in cotton plants and seeds. It is an important gene resource to gossypol-free cottonseed breeding. The objective of this research was to develop SSR markers tightly linked with Gl2^e by using the F2 segregating population containing 1599 plants derived from the cross of G hirsutum genetic standard line TM-1 and G barbadense glandless mutant line Hai-1. Genetic analysis suggested that the Gl2^e was an incomplete dominant gene. Based on the backbone of genetic linkage map from G. hirsutum x G. barbadense BC1 published by our laboratory, Gl2^e was Iocared between CIR362 and NAU2251b, NAU3860b, STV033, with a genetic distance 9.27 and 0.96 cM, respectively. This result is useful for cloning Gl2^e gene by map-based cloning method.
