AKAjanB-1 IIIb
SpeciesT. thermophila
Genetic DescriptionjanB-1/janB-1 (janB-1; III)
MAC Knockins/outs
MIC Knockins/outs
Gene of InterestJANB (janus B)

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. Also the only temperature-sensitive janus mutant. There is very little expression of the janus phenotype at 28° C, strong expression at 39°.
