摘要: 根据其他植物H+-PPase基因的保守序列设计一对简并性引物,以霸王叶片总RNA为模板,采用RT-PCR的方法扩增出H+-PPase基因片段并克隆到PUCm-T载体。阳性克隆经PCR鉴定后进行测序,序列分析结果表明,克隆到3个同源的序列片段(898 bp),编码299个氨基酸;所得序列与GenBank中注册的高等植物H+-PPase基因核苷酸序列的同源性均在69%以上、氨基酸序列的同源性达78%以上。

Abstract: Degenerate primers were designed based on conserved sequences of H+-Pase genes from other plants. Total RNA was extracted from the leaves of Zygophyllum xanthoxylum and the H+-PPase gene fragment was obtained by reverse transcription polymerase chain reaction (RT-PCR). It was cloned into PUCm-T vector and the positive clones identified by PCR were sequenced. Three H+-PPase gene fragments were gained from Z. xanthoxylum, each of which contains 898 bp and encodes a peptide of 299 amino acids. Similarity comparisons show that they share over 69% similarity in nucleotide sequence and over 78% similarity in amino acid sequence with those of other plant H+-PPase genes in GenBank.
