Fig. 6

A schematic model describing the multitrophic interaction mediated by the bacteria, positively affecting both plants and birds. After mixing of O. baccatus pulp and seeds, the “O. baccatus-oil-bomb” is activated and BenzylGSL is created (star) in the bird’s digestive system, leading to the inhibition of digestive enzyme activity (purple PacMans), and thus reduced digestion. Furthermore, the products of the “O. baccatus-oil-bomb” also cause a decrease in seedling growth. Pantoea bacteria found in O. baccatus fruits is acquired by the birds, as observed in their gut microbiota, and neutralizes the “O. baccatus-oil-bomb”, thus facilitating the bird’s digestion and restoring seedling growth.
