Two known genes were employed for a survey using restriction fragement length polymorphism (RFLP) analysis: a mammalian cytochrome P450 1A1 which shows strong xenobiotic metabolism and a NADH oxydase gene from Amphibacillus xylanus that exhibits very rapid catalytic activities on superoxide. Genomic DNA samples from haploids from 4x potatoes (Solanum tubersoum, 2n=2x=24), their relatives (S.phureja, 2n=2x=24; and S. chacoense, 2n=2x=24) and their 2x hybrids were digested with restriction enzymes Eco RI, EcoRV, HindIII, and Dra I then, the resulting digests were employed for Southern hybridization for RFLP. Even with a high stringency which is usually used for intraspecific genomic hybridization, Southern analysis revealed that a few copies of homologous fragements. While only a few bands were obtained per species, this is an intriguing report on the presence of the gene homologues associated with other organisms., 継続後誌:近畿大学先端技術総合研究所紀要 = Memoirs of Institute of Advanced Technology, Kinki University, application/pdf}, pages = {38--44}, title = {哺乳類由来の毒物代謝遺伝子CYP1A1およびバクテリア由来のNADHoxydase遺伝子に関連する相同性の高い遺伝子ホモログのジャガイモゲノムでの存在}, year = {1999} }
