FIG. 3.
Composite 2-D gels of steady-state proteins from 48-h aposymbiotic (APO) (A), 48-h symbiotic (SYM) (B), 96-h aposymbiotic (C), and 96-h symbiotic (D) light organs, identifying symbiosis-related changes in the proteome. Composite gels represent the reproducible proteins present in at least two out of three original replicate gels. Protein differences between aposymbiotic and symbiotic light organs at a given age (i.e., the data in panel A versus those in panel B or the data in panel C versus those in panel D) are depicted. All ovals indicate proteins induced in symbiotic animals, all rectangles indicate proteins repressed in aposymbiotic animals, diamonds indicate proteins induced in aposymbiotic animals, and triangles indicate proteins repressed in symbiotic animals. Blue ovals and rectangles represent symbiosis-related protein changes that were shared in 48- and 96-h symbiotic light organs. The horizontal dimension represents pH, and the vertical dimension represents Mr.
