花生蛋白激酶基因AhSTK的克隆与序列分析
Cloning and Sequence Analysis of Protein Kinase Gene AhSTK from Arachis hypogaea L.
摘要
Abstract
In this study, one new sequence total as 1 399 bp with polyA in 3' end was obtained from the cDNA library of peanut cultivar Luhua 14. By blastx analysis, it was identified as a protein kinase gene, named as AhSTK. With its cDNA sequence as template, the specific primers were designed to clone the AhSTK gene. The sequence analysis indicated that the open reading frame of AhSTK gene had 1 080 bp bases, and encoding 359 amino acids with the molecular weight about 38.9 kD and the isoelectric point about 6.42. The encoded protein had no signal peptide and transmembrane domains, and was predicted to localize in cytoplasm. Compared with the amino acid sequences of other plant protein kinases, AhSTK had the highest homol-ogy with that of soybean. Organ specificity analysis showed that its expression level was higher in peanut roots, but lower in flowers. The cloning and sequence analysis of AhSTK gene would lay foundations for further study of its biological functions and practical application.关键词
