Homozygous embryos show loss of VA2 muscle precursor cells (only 4.5% of hemisegments contain VA2 precursor cells).
ksrs628 has muscle cell of ventral acute muscle 2 | precursor phenotype, suppressible by Scer\GAL4twi.PG/cswUAS.Tag:Myr(Src64B)
Expression of csw::Src64Bsrc90.Scer\UAS under the control of Scer\GAL4twi.PG partially suppresses the loss of VA2 muscle precursor cells seen in ksrs628 embryos (14% of hemisegments have VA2 cells).
