The use of molecular data in phylogenetic reconstruction during more than three decades has greatly improved our understanding of the macroevolutionary history of the coffee family (Rubiaceae) and has provided a solid basis for improvement of its classification. Based on the results of 130 studies, among them most recent phylogenomic works, we present a consensus phylogeny and a robust classification of Rubiaceae that shed light on the evolutionary success of this highly diverse angiosperm family and can serve as a framework for ecological and evolutionary studies. There are more than 14,000 species and about 580 accepted genera of Rubiaceae that are assigned to 71 tribes, of which 68 are classified in two subfamilies (Dialypetalanthoideae with 38 tribes and Rubioideae with 30 tribes). Three tribes (Acranthereae, Coptosapelteae, Luculieae) remain unclassified as to subfamily. Sixty‐three of these 71 tribes are assigned to nine informal alliances (four in Rubioideae and five in Dialypetalanthoideae). These tribes are listed in alphabetical order within their respective alliances. Five tribes, one (Coussareeae) in Rubioideae and four (Airospermeae, Jackieae, Retiniphylleae, Steenisieae) in Dialypetalanthoideae, are excluded from these alliances due to unclear or conflicting phylogenetic positions. Thirty‐six tribes retain their tribal status but receive new generic limits to remedy their previous para‐ or polyphyletic nature. Twenty‐nine tribes not implemented in previous classifications have been added, of which three (Chioneae, Glionnetieae, Temnopterygeae) are newly described here. Basic information on phylogenies, distributions, former classifications, and useful references to previous works are provided for all accepted tribes, and future perspectives are discussed.

“…With respect to specialized metabolites, the Psychotrieae and Palicoureeae are known for their production of a structurally diverse array of alkaloids. Indeed, a chemotaxonomic approach utilizing structural groupings of Psychotrieae and Palicoureeae alkaloids has recently been employed in an attempt to disentangle the evolutionary relationships within these tribes (Berger et al, 2021).…”

Premise: The specialized metabolites of plants are recognized as key chemical traits in mediating the ecology and evolution of sundry plant-biotic interactions, from pollination to seed predation. Intra-and interspecific patterns of specialized metabolite diversity have been studied extensively in leaves, but the diverse biotic interactions that contribute to specialized metabolite diversity encompass all plant organs. Focusing on two species of Psychotria shrubs, we investigated and compared patterns of specialized metabolite diversity in leaves and fruit with respect to each organ's diversity of biotic interactions. Methods: To evaluate associations between biotic interaction diversity and specialized metabolite diversity, we combined UPLC-MS metabolomic analysis of foliar and fruit specialized metabolites with existing surveys of leaf-and fruit-centered biotic interactions. We compared patterns of specialized metabolite richness and variance among vegetative and reproductive tissues, among plants, and between species. Results: In our study system, leaves interact with a far larger number of consumer species than do fruit, while fruit-centric interactions are more ecologically diverse in that they involve antagonistic and mutualistic consumers. This aspect of fruit-centric interactions was reflected in specialized metabolite richness-leaves contained more than fruit, while each organ contained over 200 organ-specific specialized metabolites. Within each species, leaf-and fruit-specialized metabolite composition varied independently of one another across individual plants. Contrasts in specialized metabolite composition were stronger between organs than between species. Conclusions: As ecologically disparate plant organs with organ-specific specialized metabolite traits, leaves and fruit can each contribute to the tremendous overall diversity of plant specialized metabolites.

We compare patterns of specialized metabolite richness and variance among vegetative and reproductive tissues, among plants, and between species. Key results: In our study system, leaves are involved in a greater number of host-specific biotic interactions than fruit, while fruit-centric interactions are more ecologically diverse. This was reflected in specialized metabolite richness - leaves contained more than fruit, while each contained over 200 organ-specific specialized metabolites. Within each species, leaf- and fruit specialized metabolite composition varied independently of one another across plants. Specialized metabolite composition exhibited stronger contrasts between organs than between species. Conclusions: As ecologically disparate plant organs with organ-specific specialized metabolite traits, leaves and fruit can each contribute to the tremendous overall diversity of plant specialized metabolites.
