Fig. 6. Expression of At-Delta is affected after injection of At-Delta dsRNA in Achaearanea. Expression of At-Delta transcripts in germ discs derived from females injected with gfp (A,B), At-Delta^EB (C,D) or At-Delta^HH (E,F) dsRNA. A smear, not interspersed, pattern of At-Delta expression is seen in C and E. Central areas of germ discs in A,C and E are magnified in B,D and F, respectively. Arrows point at paired dots of nuclear signals implying that the transcription is active. Asterisks indicate the position of cumulus. Scale bars: 20 µm.
