| Strain Name | IA251 |
| AKA | cdaI-2 VI |
| Species | T. thermophila |
| Genetic Description | cdaI-2/cdaI-2 (cdaI-2; VI) |
| MAC Knockins/outs | |
| MIC Knockins/outs | |
| Gene of Interest | CDAI (cell division arrest I) |
| Origin | Genomic exclusion progeny following an outcross to B2079-X-II of a mutant clone that resulted from nitrosoguanidine mutagenesis in 1979 of SB210 followed by cytogamy |
| Publications | Briefly described in 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. 1628, with photos (Fig. 13). |
| Comments | Allelic to cdaI-1 (IA237) and cdaI-3 (IA282). Unequal fission-arrest following an anterior sliding of the oral primordium (39o C). Although 100% penetrant at 39o C., it is the least strongly expressed of the three known cdaI alleles; the anteriorly displaced division furrow often succeeds in completing cytokinesis, producing a small, often amacronucleate, anterior daughter cell.
