Abstract excerpt
In the preceding paper, we showed that a new 1.3 kb retron (retron-Ec107) in Escherichia coli is responsible for the biosynthesis of a branched-RNA-linked multicopy single-stranded DNA (msDNA-Ec107). Here, we show that this retron occurs in strains from different branches, A, B1, and D of a well-defined phylogenetic tree of a collection of wild E. coli. Sequence comparisons of the retrons from these three...
