Strain NameIA219
AKAdisA-1 VII
SpeciesT. thermophila
Genetic DescriptiondisA-1/disA-1 (disA-1; disA, VII)
MAC Knockins/outs
MIC Knockins/outs
Gene of InterestDISA (disorganized A)
OriginHomozygous F2 clones, obtained following an outcross to B1868 VII of an assortant derived from nitrosoguanidine mutagenesis of B1868 VI x VII in 1973, were crossed to each other in 1978 to obtain a F3 homozygote that was then crossed in 1979 to A-star to obtain an "F4" homozygote. Sister to IA217.

CommentsdisA-1 is a partially ts mutation that brings about disorganization of ciliary rows, without affecting the positioning of major cortical landmarks, or cytokinesis.
