Overexpression of Shs.PK throughout larval life and pupariation does not induce any wing phenotypes.
rhoWk; Shs.PK flies heatshocked between 6 and 9 hours after puparium formation (APF) show an extra vein phenotype much stronger than either rhoWk or Shs.PK alone. Entire intervein sectors are converted into veins. Flies heatshocked between 9 and 12 hours APF showed a moderate extra vein phenotype, consisting of ectopic crossveins and additional longitudinal veins. Between 12 and 24 hours APF heatshocking induced diffuse extra vein material between wing veins L1 and L2, and between L4 and L5. When Shs.PK flies that also carry spihs.PG are exposed to heatshock during larval or early pupal stages no phenotype is seen. When Shs.PK; rhohs.PSt; spihs.PG are exposed to during early pupariation (mostly between 6 and 12 hours APF) a phenotype is seen that is stronger than Shs.PK; rhohs.PSt alone. Also, in contrast to the diffuse ectopic veins induced by Shs.PK; rhohs.PSt, a sharp pattern of well defined forked longitudinal vein is observed. A phenotype can also be seen in the eye, in which cell death is localised at the anterior part of the eye, when heat shock is provided between 0 and 6 hours APF.
Used to generate Shs.8 and Shs.7.
