Fig 5. Genetic interactions between mutants in cycG and EGFR pathway members during wing development.

(A) The ve¹ mutant phenotype is characterized by distal gaps in the longitudinal veins (arrow points to L4). (A’) In the doubly mutant ve¹ cycG^HR7, the gap in L4 appears slightly larger (arrow). (B) Wings from doubly mutant ve¹ vn¹ flies lack all veins but small remains (arrow). (B’) This phenotype is not altered in the cycG^HR7mutant. (C) The vn¹ mutant wing has gaps in the longitudinal veins L3 and L4 (arrows), and frequently L2 does not reach the margin (asterisk) (Genotype is: ve¹ vn¹/vn¹ cycG^HR7). (C’) Wings of doubly mutant vn¹ cycG^HR7 flies display smaller gaps (arrow). (D) The net¹ mutant wing is characterized by a network of veins (arrow points to examples) (Genotype is: net¹/net¹; cycG^HR7/TM6B). (D’) More extra veins are observed in the doubly mutant net¹; cycG^HR7 (arrow).
