Comments | Partial failure to form a fission zone (39o C.) Fully penetrant at 39o C, but expressivity is far weaker than that of cdaA-1 at 39o, and instead resembles that of cdaA-1 at 35o C: dorsal ciliary rows remain continuous while ventral rows become subdivided, and a partial division furrow forms. Allelic to cdaA-1 (IA-104). The published phenotypic analysis was carried out on a different homozygous cdaA-2/cdaA-2 clone that is now extinct. Submitted by Joseph Frankel, University of Iowa |
