The MAP kinase ERK and its scaffold protein MP1 interact with the chromatin regulator Corto during Drosophilawing tissue development

Table 2 Staged corto over-expression induced ectopic vein phenotypes mostly during late larval development

Genotype	+/hs::Gal4		UAS::corto/hs::Gal4
Time of heat-shock (hours After Egg Laying AEL)	Total females observed	% females with ectopic veins	Total females observed	% females with ectopic veins
No heat-shock	32	0	195	17.9
48 h-72 h AEL (L2 larvae)	127	3.1	182	25.8
72 h-96 h AEL (early to mid L3 larvae)	123	3.2	235	29.8
96 h-120 h AEL (mid to late L3 larvae)	56	3	216	46.3^a
120 h-136 h AEL (young pupae)	78	5.1	309	31.7

For all genotypes, the first allele was brought by the mother. Only female phenotypes are reported here, but similar results were obtained for males. The number of females with ectopic veins when heat-shock was applied between 96 h-120 h AEL was compared to the ones of females with ectopic veins obtained after heat-shock applied between 72 h-96 h AEL or 120 h-136 h AEL (Z-test, ^a p < 0.001).
