从病毒感染后期的斜纹夜蛾幼虫脂肪体中提取ｍＲＮＡ，反转录合成ｃＤＮＡ探针，并使之与ＳｌＮＰＶ基因组的酶切片段杂交，将ＳｌＮＰＶｐ１０基因定位于ＢａｍＨⅠ３０千碱基片段上．ＳｌＮＰＶｐ１０是目前发现的最长ｐ１０基因；基因的启动子内含有２个ＡＴＴＧＴＡ基序，是目前所发现的ｐ１０基因中唯一含有２个Ａ／ＴＴＴＧＴＡ基序者．ＳｌＮＰＶＰ１０蛋白含有１０个七肽重复单元，可形成１个相对较长的卷曲螺旋．ＳｌＮＰＶｐ１０所在的ＯＲＦ５５２ｐ１０ＯＲＦ９４５基因簇与ＳｐｌｉＮＰＶ的ＯＲＦ５５２ｐ１０ＯＲＦ９４５基因簇各基因座位、方向及对应的氨基酸序列十分相似，表明ＳｌＮＰＶ与ＳｐｌｉＮＰＶ有很近的亲缘关系
MRNA was extracted from the body of larvae of Spodoptera litura during the late stage of virus infection, cDNA probes were reverse transcribed and hybridized with the digested fragment of SlNPV genome, and the SlNPVp10 gene was localized on the BamHI-3.0 kb fragment . SlNPVp10 is the longest p10 gene presently found; the promoter of the gene contains two ATTGTA motifs and is the only one of the 10 p10 genes currently found that contains two A / TTTGTA motifs. SlNPVP10 protein contains 10 heptad repeat units, forming a relatively long coiled-coil. SlNPVp10 ORF552 p10 ORF945 gene cluster and SpliNPV ORF552 p10 ORF945 gene cluster gene locus, orientation and the corresponding amino acid sequence is very similar, indicating that SlNPV and SpliNPV are closely related
