Phylogenomics and topological conflicts in the tribe Anthospermeae (Rubiaceae). [PDF]

Ecol Evol
Genomic data have provided new opportunities to address phylogenetic incongruence and its bases. Our work shows notable intergenomic incongruence in a tribe of the coffee family, and the null hypothesis of congruence among all sequenced loci in the individual genomes was surprisingly rejected for plastid data.

Comparative Mitogenomic Analysis Reveals Gene and Intron Dynamics in Rubiaceae and Intra-Specific Diversification in Damnacanthus indicus. [PDF]

Int J Mol Sci, 2021
The dynamic evolution of mitochondrial gene and intron content has been reported across the angiosperms. However, a reference mitochondrial genome (mitogenome) is not available in Rubiaceae.

New chromosome counts on Rubiaceae from Africa and the Western Indian Ocean islands

Nordic Journal of Botany, Volume 2023, Issue 5, May 2023., 2023
Cytological studies can provide important insights into circumscription and relationships within plant groups. Nevertheless, there is a considerable lack of cytological information, especially for large and complex groups such as the coffee family (Rubiaceae) and for plants from Africa and the Western Indian Ocean islands. In the present study, 110 new

Ecological and geological processes impacting speciation modes drive the formation of wide‐range disjunctions within tribe Putorieae (Rubiaceae)

Journal of Systematics and Evolution, Volume 59, Issue 5, Page 915-934, September 2021., 2021
Wide‐range geographically discontinuous distributions have long intrigued scientists. We explore the role of ecology, geology, and dispersal in the formation of these large‐scale disjunctions, using the angiosperm tribe Putorieae (Rubiaceae) as a case study. From DNA sequences of nuclear ITS and six plastid markers, we inferred a phylogeny, obtained an

Settling a family feud: a high‐level phylogenomic framework for the Gentianales based on 353 nuclear genes and partial plastomes

American Journal of Botany, Volume 108, Issue 7, Page 1143-1165, July 2021., 2021
Premise Comprising five families that vastly differ in species richness—ranging from Gelsemiaceae with 13 species to the Rubiaceae with 13,775 species—members of the Gentianales are often among the most species‐rich and abundant plants in tropical forests. Despite considerable phylogenetic work within particular families and genera, several alternative

Molecular systematics of the tribe Prismatomerideae (Rubiaceae) and its taxonomic consequences, with notes on the importance of the inflorescence morphology for species‐group recognition in Rennellia

TAXON, Volume 70, Issue 2, Page 324-338, April 2021., 2021
Abstract Tropical Asia is one of the centers of species diversity of flowering plants, in particular the coffee family (Rubiaceae). Prismatomerideae (the Psychotrieae alliance, subfamily Rubioideae) are a mostly Southeast Asian tribe encompassing four genera of shrubs and small trees (monospecific Gentingia and Motleyia, Prismatomeris with 16 spp ...

Table_1_Target capture data resolve recalcitrant relationships in the coffee family (Rubioideae, Rubiaceae).xlsx

, 2022
Subfamily Rubioideae is the largest of the main lineages in the coffee family (Rubiaceae), with over 8,000 species and 29 tribes. Phylogenetic relationships among tribes and other major clades within this group of plants are still only partly resolved ...

Lectotypification and a new synonym in Palicourea (Rubiaceae)

Anales del Jardín Botánico de Madrid, 2016
Here we designate specimen no. 10424 from the Museu Nacional (R) as the lectotype of Palicourea rudgeoides (Müll. Arg.) Standl. [Psychotria rudgeoides Müll. Arg., basion.], and assign a new synonym for Palicourea fulgens (Müll.
