Deletion of sequences between the insertion point of P{lArB}A208.1M2 and P{lArB}slp1A509.
one breakpoint of slp1Delta6G; a deletion of sequences between two P insertions.
Homozygotes display partial fusion of segments in a pair rule fashion, naked cuticle is still present. Heterozygotes with slp13 are lethal and transheterozygotes with Df(2L)slp-Δ34B and Df(2L)ed1 display an intermediate cuticular phenotype. One copy of the construct P{HS-slp1} can rescue transheterozygotes with Df(2L)slp-Δ34B to adulthood.
Head involution fails. Whereas the mandibular lobe does not form at all, the labial lobe deteriorates during germ band retraction, along with the mesothoracic and odd-numbered abdominal segments.
Moderate slp1 cuticle phenotype affecting the odd numbered segments. Head lobes fail to involute.
Induced on: CyO-208.
Phenotypic analysis of different slp1 and slp2 alleles establishes an allelic series: slp11 < slp1Δ41E < slp1A509 < slp13 < slp1Δ46G < slp2Δ66C < slp1Δ34B = slp2Δ34B.
