Stock IDSD00631
Strain NameIA221
AKAjanA-1 III
SpeciesT. thermophila
Genetic DescriptionjanA-1/janA-1; eja1-1/eja1-1; chx1-1/chx1-1 (janA-1; eja1-1; chx1-1; janA, eja1, cy-r, III)
MAC Knockins/outs
MIC Knockins/outs
Gene of InterestJANA (janus A) (originally reported as jan); EJA1 (enhancer of janus A); CHX1
Origin Obtained by genetic rescue of a clone selected in 1976 by Bruns and Sanford (PNAS 75: 3355-3358) using nitrosoguanidine mutagenesis followed by short-circuit genomic exclusion. Sister clone to IA220.
PublicationsGenes and this clone:
Frankel J and Jenkins LM. 1979. A mutant of tetrahymena thermophila with a partial mirror-image duplication of cell surface pattern. II. nature of genic control. J Embryol Exp Morphol 49:203-27.

Frankel J, Jenkins LM, Bakowska J. 1984. Selective mirror-image reversal of ciliary patterns intetrahymena thermophila homozygous for ajanus mutation. Development Genes and Evolution 194(2):107-20.

Cole ES and Frankel J. 1991. Conjugal blocks in tetrahymena pattern mutants and their cytoplasmic rescue. II. janus A. Dev Biol 148(2):420-8.
CommentsA mutation that causes the dorsal cell surface to be converted to a partial mirror-image of the ventral surface. Probably very similar to IA-220.
