Stock IDSD01218
Strain NameIA332
AKAjanB-1 IIIa
SpeciesT. thermophila
Genetic DescriptionjanB-1/janB-1 (janB-1; III)
MAC Knockins/outs
MIC Knockins/outs
Gene of InterestJANB (janus B)
OriginGenomic exclusion progeny following an outcross to B2079-X-II of a mutant clone that resulted from nitrosoguanidine mutagenesis in 1983 of IA264 followed by cytogamy.
PublicationsCole ES, Frankel J, Jenkins LM. 1988. Interactions between janus and bcd cortical pattern mutants in tetrahymena thermophila. Development Genes and Evolution 197(8):476-89. (emphasizes its interaction with bcd1-1).
Commentsjanus phenotype: partially reversed oral apparatus on the dorsal surface; two contractile-vacuole pore sets.

The only temperature-sensitive janus mutant. There is very little expression of the janus phenotype at 28 degrees C, strong expression at 39 degrees. A sister-clone to IA333.
