Construct: A 908bp EcoRI fragment (bp 235-1143) of the roX1 cDNA tagged with the tra2 polyadenylation signal and driven by the Hsp83 promoter.
roX1ex6 Df(1)52/Y males carrying P{w+4Δ4.3} generally do not survive to adulthood. This lethality is not substantially rescued by an autosomal copy of roX1Hsp83.5'.
lncRNA:roX1Hsp83.5' fails to rescue lncRNA:roX1ex6
