查询词典 chromosome

One was the pqsA' positive expression plasmid constructed by cloning the pqsA'-lacZ fusion digested from pYHP441 into miniCTX-1, whose sequence was then integrated into wild type PAO-1 chromosome by biparental mating procedure. The other was pqsA-E operon knock-out plasmid whose sequence between pqsD and pqsE operon was inserted by tetracycline cassette by the site specific insertion mutagenesis strategy and the mutant constructed by biparental mating of S17-1 that harbored the plasmid and pqsA' positive expression mutant.

一种是酶切质粒pYHP441获得pqsA'-lacZ片段后，亚克隆入质粒miniCTX-1中，构建成PqsA'的阳性表达质粒，随后将构建的质粒，通过双亲交配过程整合入野生型铜绿假单胞菌株PAO-1染色体组中；另一种是通过点特异插入诱变策略，将四环素基因盒插入启动子pqsD和pqsE之间，构建的阴性质粒转化入大肠杆菌S17-1株后，和上述pqsA'阳性表达突变株进行双亲交配过程。

It is intimately involved in spindle formation and chromosome segregation during mitosis. Now, the over-expression of PLK1 has been found in various primary carcinomata, and indicated the probability of PLK1 as a new tumor marker.

近年来，研究发现PLK1（polo-like kinase 1）基因在有丝分裂过程中起重要的调节功能，并且在多种的人类肿瘤包括肺癌中发现PLK1基因表达升高，提示PLKl的增长表达在细胞的增殖中起重要作用，预示PLK1可能是一个新的肿瘤标记物。

Ligusticum 、 Cyclorhiza 、 Tongoloa 、 Carum 、 Oenanthe 、 Pternopetalum and Chamaesium were carried out. Our cytological results suggest that polyploidy did not play an important role in the chromosome evolution of Ligusticum.

The apical bud of Celosia cristata was immersed in 0.05%, 0.1%, 0.15% and 0.2% colchicine solutions for 12 h, 24 h, 36 h, 48 h respectively and the chromosome numbers of the root tip cells in the regenerated plantlets were examined, which showed that the treatment with 0.15% colchicine solution for 36 h would be the best combination that the polyploid rate could reached 23.3%.

采用浸泡法将鸡冠花营养芽在0.05%、0.1%、0.15%和0.2%不同秋水仙溶液浓度下分别处理12h、24h、36h和48h，并对诱导处理后获得的再生植株进行鉴定，得出以0.15%秋水仙素溶液浸泡36h为诱导多倍体的最佳处理组合，诱导率达23.3%。
