Figure 3From: Loss of genes for DNA recombination and repair in the reductive genome evolution of thioautotrophic symbionts of Calyptogena clamsOpen reading frames and nucleotide sequence homologies in amplicons for the mutY region amplified from Calyptogena clam symbiont genomes. A, ORFs in the mutY-amplicons. Filled pentagonal column, intact gene. Open pentagonal column, pseudogene or remnant of gene. Gray, part of metA (homoserine O-succinyltransferase). Blue, mutY. B, Aligned mutY-amplicons showing their nucleotide sequence identities and deletion profiles compared with that of the C. phaseoliformis symbiont. Dotted lines, deletions.Back to article page
