Consequences of interspecific plant hybridization on metabolic diversity in naturally occurring hybrid swarms.

ABSTRACT: Interspecific hybridization has influenced plant evolution and diversification. However, how hybridization may affect metabolic diversity, especially in naturally occurring hybridization zones, is unclear. In this study, we selected a Baccharis (Asteraceae) hybrid complex consisting of B. linearis, B. macraei, and B. × intermedia and characterized its metabolic profiles in multiple hybridization zones in central Chile to determine how hybridization affects plant chemistry. Untargeted liquid chromatography-time of flight mass spectrometry analysis of a total of 411 plant individuals collected in the field revealed that the hybrid B. × intermedia combines the metabolic profiles of its two parental species, B. linearis and B. macraei, independent of season, location, and environment.
