Fig. 2. Expression patterns of Coro transcripts. (A) The expression pattern of 409-GAL4 in wing discs revealed by UAS-nuclear lacZ (green). Note that 409-GAL4 is expressed only in the peripodial membrane. The disc proper is stained for Wingless (red). (B-D) Embryonic expression patterns of Coro. It is ubiquitously expressed in cellular blastoderm (B), extended germ band (C) and retracted germ band (D) stages. RNA in situ hybridization was done using antisense probes for LD32977. (E,F) Embryos of cellular blastoderm (E) and extended germ band (F) stages probed with sense RNA used as a negative control. (G-H) Post-embryonic expression patterns of Coro. It is expressed at high levels in eye, leg (G) and wing (H) imaginal discs. Note that it is expressed at very low levels in the larval CNS (G).
