*: Asterisk denotes derivative strains, i.e. R3460 is strain R652 carrying the vector pDD515. The marked strains are not included in computing the incidence of the wild-type vapDHi allele versus the truncated allele. Independent strains are not marked with an asterisk. †: Type of vapDHi allele: WT = wild type (91 amino acids); TV = truncated version (45 amino acids). ‡: Site from which strains were isolated.
