Mutants exhibit a strong "anti-ftz" phenotype. In 50% of first instar larvae, the denticle belts of T1, T3, A2, A4, A6 and A8, and the ventral pits and Keilin's organs of T1 and T3 are deleted.
ftzΔ151-209.αTub84B is a suppressor of lethal | recessive | maternal effect phenotype of ftz-f1209
ftzΔ151-209.αTub84B is a suppressor of abdominal 1 ventral denticle belt phenotype of ftz-f1209
ftzΔ151-209.αTub84B is a suppressor of parasegment 2 phenotype of ftz-f1209
ftzΔ151-209.αTub84B is a suppressor of parasegment 4 phenotype of ftz-f1209
ftzΔ151-209.αTub84B is a suppressor of parasegment 6 phenotype of ftz-f1209
ftzΔ151-209.αTub84B is a suppressor of parasegment 8 phenotype of ftz-f1209
ftzΔ151-209.αTub84B is a suppressor of abdominal 3 ventral denticle belt phenotype of ftz-f1209
ftzΔ151-209.αTub84B is a suppressor of abdominal 5 ventral denticle belt phenotype of ftz-f1209
ftzΔ151-209.αTub84B is a suppressor of abdominal 7 ventral denticle belt phenotype of ftz-f1209
ftzΔ151-209.αTub84B is a suppressor of abdominal 9 ventral denticle belt phenotype of ftz-f1209
ftzΔ151-209.αTub84B is a suppressor of mesothoracic ventral denticle belt phenotype of ftz-f1209
ftzΔ151-209.αTub84B is a suppressor of parasegment 10 phenotype of ftz-f1209
ftzΔ151-209.αTub84B is a suppressor of parasegment 12 phenotype of ftz-f1209
ftzΔ151-209.αTub84B is a suppressor of parasegment 14 phenotype of ftz-f1209
When ftzΔ151-209.αTub84B is expressed in embryos derived from ftz-f1209 mothers, the denticle belt phenotype is partially suppressed. When sperm expressing ftzΔ151-209.αTub84B is used to fertilise these eggs, no suppression is seen.
