Deletion of sequences between the insertion point of P{lArB}slp1A509 to within slp2 completely removing P{lArB}A208.1M2 insertion.
Fusion of abdominal segments A1 and A2, and A3 and A4. Naked cuticle found in the posterior part of each segment is either missing or replaced by denticles.
Strong slp2 phenotype.
slp1Δ34B, slp2Δ34B has embryonic/larval dorsal vessel & embryonic myoblast phenotype, non-suppressible by Scer\GAL4twi.PG/wgUAS.cAa
slp1Δ34B, slp2Δ34B has embryonic/larval somatic muscle & embryonic myoblast | dorsal phenotype, non-suppressible by Scer\GAL4twi.PG/wgUAS.cAa
Df(2L)slp-Δ34B embryos (which are mutant for both slp1 and slp2) lack eve-expressing heart or muscle precursors.
Induced on: CyO-208.
Phenotypic analysis of different slp1 and slp2 alleles establishes an allelic series: slp11 < slp1Δ41E < slp1A509 < slp13 < slp1Δ46G < slp2Δ66C < slp1Δ34B = slp2Δ34B.
