title: Evolution of the ISCR3 group of ISCR elements.
abstract: The ISCR elements ISCR3, ISCR4, ISCR5, ISCR14, and ISCR16 all share a percent G+C of 68 to 69%. They also share between 75% and 97% identity in their transposase open reading frames. Furthermore, with the exception of ISCR5, they are all found adjacent to sections of groEL that display the highest identity to the same gene from Xanthomonas spp. The combined information is consistent with the descent from an ancestral ISCR element in a Xanthomonas-like organism.
