Drosophila embryogenesis
se- |
Distalless expression
in larval wing imaginal discs in both Junonia sp. and Bicyclus sp.
is correlated with the eyespots in adult wings. (Images by Julie
Gates and Steve Paddock; morphing by Eric Hazen) featured in "Learning to Fly". |
Spalt (Sal)
in purple and Engrailed/Invected (En/In) in green expression define
territories that are correlated with the concentric rings of the
eyespot patterns in Bicyclus sp. (Images by Craig Brunetti; animation by Steve Paddock) featured in "Little Wing". From Brunetti, et al.(2001) Current Biology, 11:1578-1585. |

Distalless expression
and focal signaling. (Images by Julie Gates and Steve Paddock;

The expression
of En/Inv and sal is altered in the B. Anynana eyespot mutant
Goldeneye. (images by Craig Brunetti; animation by Steve
Paddock). |
The diversity
of eyespot patterns is the result of altering the expression of
both regulatory and pigmentation genes. (Images by Craig Brunetti
and animation by Steve Paddock). |
