| 摘 要： | 本文利用比较基因组学的方法从大白菜的基因组中解析出两个成花素基因brft1和brft2,并对这两个基因的结构、顺式调控元件以及遗传进化进行了分析。结果表明,brft1和brft2都含有4个外显子,编码区大小均为528 bp,二者预测编码蛋白的序列一致性为90.29%, 说明这两个基因序列存在某种程度的分化。进化分析表明这两个基因应为拟南芥ft和tsf基因的直系同源基因。另外,这两个基因都含有响应激素和逆境信号的顺式调控元件,而且不尽相同,说明这两个基因的表达调控有所不同,可能在功能上存在一定分化。本研究为进一步揭示大白菜ft基因在开花和逆境响应中的功能奠定了基础。

| Abstract: | Two florigen genes BrFT1 and BrFT2 were analyzed from the genome of Chinese cabbage(Brassica rapa subsp.pekinensis) by the comparative genomics method,and their structure,cis-acting elements and phylogeny were investigated.The results showed that the genomic sequence of the two genes both contained 4 exons,and the coding region was 528 bp.The sequence identity of the predicted proteins encoded by them was 90.29%,which suggested they should be functionally conserved.Phylogeny analysis indicated that BrFT1 an... |
