Deletion within Zasp67; exons 2, 3 and 4 are replaced with a cassette encoding an attP site, GAL4::VP16 driver coding sequence, and a loxP cassette that contains a w+* marker.
Approximate deletion breakpoints determined from reported guide RNA sequences; exons 2, 3 and 4 of Zasp67 are replaced with a cassette encoding an attP site, a GAL4::VP16 driver coding sequence, and a loxP cassette that contains a w+* marker.
Zasp67CRISPR/+, Zasp67CRISPR/Zasp67CRISPR and Zasp67CRISPR/Df(3L)BSC393 adults are flightless but do not show climbing defects; their indirect flight muscles exhibit substantial and progressive structural defects ranging from split myofibrils to extended or broken Z-discs; these muscle defects are not visible at the pupal stage.
The indirect flight muscles of Zasp67CRISPR homozygotes show Z-disc aggregation, although Z-disc size is unaffected.
Zasp67CRISPR has indirect flight muscle cell phenotype, enhanceable by Zasp66CRISPR/Zasp66CRISPR
Zasp67CRISPR has Z disc | adult stage phenotype, enhanceable by Zasp66CRISPR/Zasp66CRISPR
Zasp67CRISPR/Zasp67CRISPR is an enhancer of indirect flight muscle cell phenotype of Zasp66CRISPR
Zasp67CRISPR/Zasp67CRISPR is an enhancer of Z disc | adult stage phenotype of Zasp66CRISPR
Double Zasp66CRISPR, Zasp67CRISPR homozygotes show more a severe Z-disc aggregation in indirect flight muscles than either single homozygous mutant. The z-discs of doublemutants are also enlarged, as compared to either single mutant or wild-type controls.
