Stock IDSD01511
Strain NameIA123
AKAcdaC-2 VII
SpeciesT. thermophila
Genetic DescriptioncdaC-2/cdaC-2 (cdaC-2; VII)
MAC Knockins/outs
MIC Knockins/outs
Gene of InterestCDAC (cell division arrest C) Originally published as mo3b
OriginF3 following outcross to B1868 VI of an assortant derived from nitroso-guanidine mutagenesis of B1868 VI x VII in 1973. It was originally believed to require homozygosity of alleles at two genes for full expression, but a second set of crosses gave results consistent with homozygosity for a single recessive allele being sufficient.
