When the aphid embryo was incubated in vitro, it synthesized proteins identical with those which were produced in vivo. The endosymbiont in the embryo in vivo synthesized symbionin, an acidic protein of 63 kD, almost exclusively while that in the embryo incubated in vitro produced several other proteins in addition to symbionin. These new proteins were among those which were synthesized by the isolated endosymbiont when incubated in vitro. It is likely that the aphid embryo in the ovanole is stringently controlled by some maternal factor(s) in order to synthesize symbionin, which is probably essential for the post-embryonic development of the host insect.
