- 摘要:
- 以温敏型黄瓜‘C09-123’为试材,通过对不同夜温处理的黄瓜幼叶进行差异蛋白质鉴定,筛选出一个与低夜温影响黄瓜雌性形成密切相关的蛋白,采用生物信息学方法,对该蛋白进行生物信息学分析,并运用基因克隆技术克隆了该基因,以期为明确该基因在黄瓜性别分化中的作用机制奠定基础,也为进一步试验研究提供基因材料。结果表明:该基因全长870 bp,编码289个氨基酸,该基因编码的蛋白质属于叶绿体中一个不稳定的疏水蛋白质,无明显信号肽,无跨膜结构。与甜瓜为同一进化分支,同源性较高。该蛋白属于PAP-fibrillin蛋白家族,因此将编码该蛋白的基因命名为CsPAP-fib。
- Abstract:
- The tempetature-sensitive cucumber cultivar ‘C09-123’ was used as material in this study,a protein which concerned the formation of cucumber femaleness under low night temperature had been found by the identification of differential proteins in cucumber young leaves treated by different night temperatures,then was analysed by bioinformatics technology.The gene encoded this protein was cloned by cloning technique to establish a foundation for confirming the functional mechanisms of CsPAP-fib in cucumber sex differentiation,and provide the genetic material for further research.The results showed that the gene length was 870 bp,encoding 289 amino acids.The protein encoded by this gene was an unstable,hydrophobic and non-transmembrane protein without signal peptide located in chloroplast,and it was highly homologous to Cucumis melo L.The gene was named as CsPAP-fib,based on the protein family PAP-fibrillin which the protein encoded by the gene.
