摘要: 根据GeneBank中已登记的番茄果糖激酶基因的保守序列设计特异引物,以普通栽培型番茄辽园多丽的果实为材料提取总RNA,采用RT-PCR方法,扩增出果糖激酶基因cDNA序列的部分片段并克隆到pBS-T载体中.测序结果表明,LeFRK1-LeFRK3分别与番茄植物中已知该基因的核苷酸序列相似性高达99%以上,构建了一个番茄、马铃薯、烟草及拟南芥植物中FRK基因的系统进化树.采用半定量RT-PCR方法对番茄果实不同发育时期的表达进行检测,FRK1-FRK3在番茄果实发育的过程中均有表达,但在花后2~3 d时表达量较高.

Abstract: PCR primers were designed which based on the consensus domain of some fructokinase genes from tomato registered in GenBank.The cDNA fragments were obtained by reverse transcriptional polymersae chain reaction(RT-PCR)using the whole RNA of tomato,Liaoyuan Duoli(Solanum lycopersicum),as the templates.The fragments were cloned into pBS-T vector and then sequenced.The sequencing results showed highly homology(above 99%) in nucleotide sequence with the published sequences of tomato.A phylogenetic tree of FRK genes from Arabidopsis thaliana,Solanum tuberosum,Nicotiana tabacum and Solanum lycopersicum was constructed.The expression patterns of the cDNAs were examined in tomato fruit during different stages by semi-quantitative RT-PCR.FRK1-FRK3 was expressed in the whole stage of tomato fruit development,and strongly expressed from 25 to 35 days after anthesis.

Key words: Tomato, Fructokinase, RT-PCR, Sequence analysis, Gene expression
