Detailed Description
Statement
Reference

Homozygous tou2 mutants give rise to escapers lacking dorsocentral (DC) bristles (1.4 bristles per heminotum compared to 2.0). tou2/Df(2R)en-SFX31 mutants exhibit an average of 1.25 dorsocentral bristles per heminotum compared to 2.0 in wild-type controls.

tou2 flies show the same wing defect as tou1.

Additional Comments
Genetic Interactions
Statement
Reference

tou2 ; pnrD1/+ flies exhibit 2.17 dorsocentral bristles per heminotum compared to 3.34 per heminotum in pnrD1 heterozygotes, indicating that tou2 suppresses the phenotype. tou2/+ ; pnrVX1/+ flies exhibit on average 1.57 dorsocentral bristles per heminotum, compared to 1.86 bristles per heminotum in pnrVX1 heterozygotes, 1.4 bristles per heminotum in tou2/+ and 2.0 dorsocentral bristles per heminotum in wild-type. tou2 ChiE flies exhibit 1.11 dorsocentral bristles per heminotum compared to 2.0 in wild-type controls. tou2/+ heterozygotes, in which IswiK159R.Scer\UAS.T:Ivir\HA1 is being expressed under the control of Scer\GAL4pnr-MD237, exhibit a reduction in the number of dorsocentral bristles (an average of 1.14 bristles per heminotum compared to 2.0 in wild-type). tou2 homozygotes, in which IswiK159R.Scer\UAS.T:Ivir\HA1 is being expressed under the control of Scer\GAL4pnr-MD237, exhibit a reduction in the number of dorsocentral bristles (an average of 0.75 bristles per heminotum compared to 2.0 in wild-type). tou2 ; osa616/+ flies exhibit an average of 1.97 dorsocentral bristles per heminotum, compared to 1.4 in tou2/+ flies and 2.0 in wild-type controls.

Has no effect on the arista to leg transformation phenotype seen in Df(2R)Dll-MP heterozygotes.
