Strain Name | IA221 |
AKA | janA-1 III |
Species | T. thermophila |
Genetic Description | janA-1/janA-1; eja1-1/eja1-1; chx1-1/chx1-1 (janA-1; eja1-1; chx1-1; janA, eja1, cy-r, III) |
MAC Knockins/outs | |
MIC Knockins/outs | |
Gene of Interest | JANA (janus A) (originally reported as jan); EJA1 (enhancer of janus A); CHX1 |
Origin | Obtained by genetic rescue of a clone selected in 1976 by Bruns and Sanford (PNAS 75: 3355-3358) using nitrosoguanidine mutagenesis followed by short-circuit genomic exclusion. Sister clone to IA220. |

Comments | A mutation that causes the dorsal cell surface to be converted to a partial mirror-image of the ventral surface. Probably very similar to IA-220. |
