Gene of Interest
Origin"Derived from CU399" (Tiedtke et al. 1988). "Preliminary genetic data show that the phg- character is probably caused by a recessive single-gene mutation, that chromosomally maps on chromosome 3" (Hunseler & Tiedtke, 1986. Society of Protozoologists Abstract #124). Obtained from Arno Tiedtke, Feb. 1989.

CommentsThe Frankel lab could not obtain progeny from crosses using this stock. Its observations are consistent with the reported temperature-sensitive food-vacuoleless phenotype, but not consistent with the reported total loss of oral structures. This stock exhibits multiple unique morphogenetic phenotypes at 37.5o C.: see Frankel (2008: p. 1626, 1632). The Iowa stock is designated II8G-IA to distinguish it from the II8G stock, deposited by L. Rasmussen at the American Type Culture Collection. ATCC.
