A bt - e. coli shuttle vector pht315 was deleted its replication region of bt, then constructed a novel vector named pht315 - 1 which composed a multiple cloning site, erythromycin and ampicillin - resistance marker and could only replicated in e. coli. used pht315 - 1, a 5273 bps dna fragment carrying a novel bt plasmid replicon was isolated and registered in genbank as ay278324. sequence analysis showed that there were at least three orf ( open reading frame ) in the cloned dna encoding 501, 333, 183aas. orfl had 98 % identities with replicating related protein ori43 of bt strain hd263. the others were no homology to any published bt replicating related protein. after continuous cultured for 70h at 30 c without antibiotic selecting press. the stability of plasmid carrying cloned replicon in bt acrystalliferous mutant strain hd73 cry was more than 98 %. and growth curve also showed that the novel replicon was stable and could replicate normally
進一步序列分析表明該復制區至少有3個較大的orf ，分別編碼501 ， 333 ， 183個氨基酸。其中orf1蛋白序列與hd263復制蛋白ori43的同源性為98 ，而另外兩個orf和genbank己公布的bt復制相關蛋白無同源性。 30連續培養72h ，復制區質粒在bt無晶體突變株hd73cry ~ -中穩定性達98以上， 30h生長曲線也表明該復制區能夠在bt中穩定復制和遺傳，對受體菌株無明顯不良影響。
