摘要: 应用锚定的3′RACE方法,对褐飞虱Nilaparvata lugens (Stal)肌动蛋白基因3′末端进行了扩增、克隆和测序, 并对所得到的5个cDNA片段的不译端的序列进行了比较。结果显示:BPH-A和BPH-D与其他序列不同;BPH-B、BPH-C和PBH-E三条片段的不译端的序列很相似,只是长度不同。另外,所得序列中所含翻译区的氨基酸序列高度保守,根据肌动蛋白基因结构特点可以推断BPH-A和BPH-D属肌肉特异型肌动蛋白基因,BPH-B、BPH-C和BPH-E属细胞质特异型肌动蛋白基因。

Abstract: The 3′terminal of the actin genes in the brown planthopper, Nilaparvata lugens (Stal) was amplified, cloned and sequenced using the anchored 3′RACE method. Through homologous comparison of these sequences in untranslated regions, we found that BPH-A and BPH-D were different from other sequences, and that BPH-B, BPH-C and BPH-E had the same sequence except for different 3′ terminal sites. The amino acid sequence of the 3′ terminal of the actin genes in N. lugens is highly conservative. According to structural characteristics of the actin genes, we conclude that BPH-A and BPH-D are muscle specific while BPH-B, BPH-C and BPH-E are cytoplasm specific.
