FlyBase curator comment: this entry is used to capture phenotypic information when the particular allele (or allele combination) used by the author could not be determined but the context of the experiment suggests that the phenotype being described is some kind of loss of function.
Heterozygous larvae have a significantly higher number of plasmatocytes than wild-type larvae. This increase in plasmatocytes is present both early and late in the third instar.
[+]/Cyt-b5unspecified is rescued by Cyt-b5UAS.cKa/Scer\GAL4He.PZ
The dominant effect of Cyt-b5unspecified on plasmatocyte number is rescued by expression of Cyt-b5Scer\UAS.cKa under the control of Scer\GAL4He.PZ.
