摘要: Abstract The efficiency of co-transformation in Penicillium chrysogenum Wisconsin 54-1255 pyrG − and the fate transforming DNA were studied using an integrative (pEF43) autonomous replicating plasmid (pAM9L). results showed a frequency nearly 70% all transformants tested. total transformation was shown to be dependent on marker used as transformant selection (i.e., markers or vector). Analysis plasmids re-isolated from several co-transformants that different populations co-exist fungal host. Interestingly, studied, found autonomously without integrating into host genome. In some cases, co-integrates formed by recombination between (pAM9L) plasmids. However, unexpectedly non-reorganised pEF43 assays rescued co-transformants.
