查询词典 x chromosome

Chromosome pairing behavior in meiosis of the hybrid F1 was carried out. Results showed that in an average , 1.25 rod bivalents were observed in one PMC, meiotic configuration was 2n=14=11.49Ⅰ+1.25Ⅱ(Xta=1.25) and most of PMCs possessed 1～5 bivalens, indicating that the relatively high homeology was detected between the D genome of Ae.tauschii and the V genome of D.villosum. The morphological differences between F1 hybrids and their parents were significant. F1 plants were highly self-sterile, but partially self-fertile after treated by chromosome doubling technique.

对杂种F1花粉母细胞减数分裂中期Ⅰ染色体配对行为进行观察发现，"节节麦×簇毛麦"杂种F1平均每PMC有1.25个棒状二价体，染色体的平均构型为2n=14=11.49Ⅰ+1.25Ⅱ(Xta=1.25)，大部分被观察的细胞出现1～5个二价体，表明节节麦D染色体与簇毛麦V染色体间具有相对较高的部分同源配对， D和V染色体之间存在一定的部分同源性。F1植株高度自交不育，经染色体加倍处理后能够自交结实。

Experiment result shows that 1.there are totally 26 chromosomes;2.chromosome 1,2,5,7,8,10,12 have central centromeres;chromosome3,4,6,9,11,13 have vise central centromeres;sex chromosome cannot be detected.

Our results demonstrated that the IVS of Cb is a highly conservative element in the chromosome and it is different from its homologous elements existing in the chromosome of Spirochete which are highly divergent among strains. The difference of Cb IVSs is related to the geographic distribution of the organisms and the Yunnan strains probably belong to a subspecies of Cb.

Cb 23S IVS为高度保守基因片段，与高度异质性的钩端螺旋体的同源性基因片段不同；云南株和其它6株的IVS差别与Cb分离株的地理分布的不同有关，云南分离株可能为一亚种。
