Stock IDSD01517
Strain NameIA285
SpeciesT. thermophila
Genetic DescriptionpsmD1/psmD-1 (psmD-1; III)
MAC Knockins/outs
MIC Knockins/outs
Gene of InterestPSMD (pseudomacrostome D)
OriginGenomic exclusion progeny following an outcross to B2079-X-II of a mutant clone that resulted from nitrosoguanidine mutagenesis in 1981 of IA264 followed by cytogamy.
PublicationsBriefly described in:
xFrankel J, Jenkins LM, Bakowska J, Nelsen EM. 1984b. Mutational analysis of patterning of oral structures in tetrahymena. I. effects of increased size on organization. J Embryol Exp Morphol 82:41-66.

Frankel J. 2008. What do genic mutations tell us about the structural patterning of a complex single-celled organism? Eukaryot Cell 7(10):1617-39, (p. 1627).
CommentsPleiotropic: elongated phenotype with development of large oral-replacement or misplaced cell division oral primordia, especially in rich medium, at 39o C. Also frequent abnormal internal organization of oral structures, and fission arrest. The only known mutant allele of this gene, located on chromosome 3R. This is the most highly pleiotropic of the PSM mutant genes.
