PCA-DA analyses to determine the heterogeneity ofO. unilateralis s.l.on different ant species’ brains.(A) PCA-DA plot showing the clustering of O. unilateralis s.l. secretion in the presence of different ant species’ brains kept ex vivo in Schneider’s insect medium and the medium without ant brains. (B) PCA-DA plot showing the clustering of different ant species’ brains kept ex vivo and the medium by itself without fungal growth that served as controls in this study. (C-F) PCA-DA plots showing the clustering per species of O. unilateralis s.l. secretion in the presence of ant brains of that species versus secretion in the medium without ant brains, ant brains kept ex vivo without fungal growth and the Schneider’s insect medium by itself.
