Fig. 3From: Further evidence that mechanisms of host/symbiont integration are dissimilar in the maternal versus embryonic Acyrthosiphon pisum bacteriomeApNEAAT1 localization in embryos during symbiont transmission (stages 7, 9, and 11). Signals representing ApNEAAT1 immunoactivity are shown in green, F-actin (Phalloidin) is in red, and nuclei (DAPI) are in blue (color key below figure). Confocal images a–c show ApNEAAT1 antibody staining and a’–c’show merged results for ApNEAAT1 antibody, F-actin, and nuclei. Confocal images d–f are preadsorbed controls showing the antibody signal and d’–f’ are preadsorbed controls showing the merged results for ApNEAAT1 antibody, F-actin, and nuclei. g–i Illustrations of each embryonic stage. White arrowheads mark ApNEAAT1 antibody localization to the maternal follicular epithelium; arrows indicate somatic cell membrane localization.
