Interspecific hybridization events have played a major role in plant speciation, yet the evolutionary origin of hybrid species often remains enigmatic. Here, we inferred the evolutionary origin of the allotetraploid species Coffea arabica, which is widely cultivated for Arabica coffee production. We estimated genetic distances between C. arabica and all species that are known to be closely related to C. arabica using genotyping‐by‐sequencing (GBS) data. In addition, we reconstructed a time…

The complete chloroplast genome of Coffea liberica (Gentianales: Rubiaceae)

Abstract Coffee is one of the most popular beverages around the world. As one of the best-known coffee species, Liberian coffee (Coffea liberica Bull ex Hiern 1876) has a high resistance to leaf

Coffea cytogenetics: from the first karyotypes to the meeting with genomics.

TLDR
The Coffea cytogenetics, from the first chromosome counting, encompassing the karyotype characterization, chromosome DNA content, and mapping of chromosome portions and DNA sequences, until the integration with genomics, is reviewed and new karyotypes are presented.

Vulnerability of coffee (Coffea spp.) genetic resources in the United States

TLDR
The present coffee crop vulnerability statement developed by the Coffee and Cacao Crop Germplasm Committee provides background information about the crop, threats to Coffee genetic resources, current status of coffee genetic resources and capacities, and projected future needs of coffee research, breeding, and production.

Coffee Leaves: An Upcoming Novel Food?

TLDR
The biosynthesis, metabolism, and distribution of the 4 main classes of secondary metabolites present in coffee leaves, their main pharmacological and toxicological aspects, and their main roles in planta are highlighted.

Genome-Wide Identification, Characterization, and Comparative Analysis of NLR Resistance Genes in Coffea spp.

TLDR
The NLR-annotator tool used in this study showed extremely high sensitivities and specificities and increased the detection of putative NLRs in the reference coffee genomes, which will support functional studies and contribute to a more precise use of these genes for breeding disease-resistant coffee cultivars.

In situ hybridization identifies the diploid progenitor species of Coffea arabica (Rubiaceae)

TLDR
These results confirm the allopolyploid nature of C. arabica and show that C. congensis and C. eugenioides are the diploid progenitors of the tetraploid species.

Genome rearrangements derived from homoeologous recombination following allopolyploidy speciation in coffee.

TLDR
The detection of a large number of homoeologous exchange events (HEEs) shared by all accessions of C. arabica strongly reinforces the assumption of a single allopolyploidization event, suggesting that HEE accumulates gradually.

Coffea anthonyi, a new self-compatible Central African coffee species, closely related to an ancestor of Coffea arabica.

TLDR
A new small-leaved Central African species of Coffea anthonyi Stoff from Cameroon and the Republic of Congo is formally described and is of particular interest from a phylogenetic as well as from a breeding point of view.

Towards a Phylogeny for Coffea (Rubiaceae): identifying well-supported lineages based on nuclear and plastid DNA sequences.

TLDR
Several major lineages with geographical coherence, as identified in previous studies based on smaller data sets, are supported and others with either geographical or ecological correspondence are recognized for the first time.

First Coffea arabica karyogram showing that this species is a true allotetraploid

TLDR
This work suggests that C. arabica is a true non-segmental allotetraploid but originated from different species exhibiting similar and distinct chromosomes.

Evolutionary history of the Afro-Madagascan Ixora species (Rubiaceae): species diversification and distribution of key morphological traits inferred from dated molecular phylogenetic trees.

TLDR
Novel ecological opportunities resulting from climate-induced habitat fragmentation and corolla tube length diversification are likely to have facilitated species radiation on Madagascar, suggesting that the same ecological and selective pressures are acting upon taxa from both Madagascan lineages.

Micro-collinearity and genome evolution in the vicinity of an ethylene receptor gene of cultivated diploid and allotetraploid coffee species (Coffea).

TLDR
Analysis of the Arabica and Robusta coffee genomes revealed differential insertion events that contributed to the size increase in the C(a) sub-genome compared to its diploid relative, and showed that insertion of a Ty1-copia LTR retrotransposon occurred specifically in C. arabica, probably shortly after allopolyploid formation.

A single polyploidization event at the origin of the tetraploid genome of Coffea arabica is responsible for the extremely low genetic variation in wild and cultivated germplasm

TLDR
The extremely low levels of variation observed in the species, as a consequence of the polyploidization event, make the exploitation of diversity within the species for breeding purposes less interesting than in most crop species and stress the need for introgression of new variability from the diploid progenitors.

Reproductive isolation, gene flow and speciation in the former Coffea subgenus: a review

TLDR
The notion of metaspecies is defined in the case of the former Coffea by extension of the concept of metapopulation to species in relation with sympatry situations, gene flow possibilities and forest fragmentation.

Phylogenetic relationships of coffee-tree species (Coffea L.) as inferred from ITS sequences of nuclear ribosomal DNA

TLDR
The results were in contradiction with the present classification of coffee-tree taxa into two genera, namely Coffea and Psilanthus, and additivity of parental rDNA types was not observed in the allotetraploid species C. arabica.
