FIG. 2.

Number of changes in steady-state protein profiles in light organs as a function of both age and symbiotic state. Age-related protein changes at either 48 or 96 h are categorized as follows: induced (present in both aposymbiotic [APO] and symbiotic [SYM] light organs but absent from hatchling light organs) and repressed (present in hatchling light organs but absent from both aposymbiotic and symbiotic light organs). Symbiosis-related protein changes at 48 and 96 h are categorized as follows: induced in symbiotic (present in symbiotic but absent from aposymbiotic and hatchling), repressed in symbiotic (absent from symbiotic but present in aposymbiotic and hatchling), induced in aposymbiotic (present in aposymbiotic but absent from symbiotic and hatchling), and repressed in aposymbiotic (absent from aposymbiotic but present in symbiotic and hatchling) light organs.
