  • a The mutations listed indicate intergenic differences between the adapted clones and the ancestral wild type. A positive distance from a proximal gene represents the downstream location of the mutation relative to the gene's translation stop site, whereas a negative distance represents the mutation's upstream location relative to the gene's translation start site. nt, nucleotide position number.
