According to the RFLP analysis and phylogeographic pattern, combined the radiation record of A. pernyi, it was inferred that the 12 cultivars used might origin from two different maternal ancestors, one from Henan province and the other from Shandong.

根据对12个柞蚕品种的线粒体AT富集区和tRNA〓基因序列的模拟酶切和种内系统发育分析结果，结合柞蚕种的传播历史记载，本文推测所分析的12个品种可能有2个母系来源：一个来源于山东，一个来源于河南。

Through the traditional physiological and biochemical method, together with the 16SrDNA sequence homology and phylogenetic analysis, the strains were identified. The result shows they belong to the genus photobacterium, but they differ from any species of this genus in some characteristic which suggests they might be new species, and their taxonomic placement needs more information on genes level.

对两株菌进行鉴定，分析其生理生化特征和16SrDNA产物序列，确定这两株菌均属于发光杆菌属，但是和该属的各种还有一定差异，对其分类地位的最后确定还需进一步的系统发育学分析。
