Abstract Restriction fragment length polymorphism (RFLP) markers were used in combination with genomic in situ hybridisation (GISH) to investigate the origin of the allotetraploid species Coffea arabica (2n = 44). [...] Key Method By comparing the RFLP patterns of potential diploid progenitor species with those of C. arabica, the sources of the two sets of chromosomes, or genomes, combined in C. arabica were identified. The genome organisation of C. arabica was confirmed by GISH using simultaneously labelled…Expand

Phylogenomic analysis clarifies the evolutionary origin of Coffea arabica L
TLDR
The age of the hybridization event coincides with periods of environmental upheaval, which may have induced range shifts of the progenitor species that facilitated the emergence of C. arabica. Expand
Segregation analysis of molecular markers in a population derived from Coffea liberica Hiern x C. eugenioides L.
TLDR
The knowledge derived from this study allowed to better understand the genetic segregation behavior of these markers with the aim of developing genetic maps that have important applications for coffee breeding programs as well as other commercial crops. Expand
Phylogenomic analysis clarifies the evolutionary origin of Coffea arabica
TLDR
The evolutionary origin of the allotetraploid species Coffea arabica, which is widely cultivated for Arabica coffee production, is inferred using genotyping‐by‐sequencing (GBS) data and reconstructed a time‐calibrated multilabeled phylogenetic tree of 24 species to estimate the age of the C. arabicas hybridization event.

Construction and characterization of a BAC library from the Coffea arabica genotype Timor Hybrid CIFC 832/2
TLDR
The construction and characterization of a Bacterial Artificial Chromosome (BAC) library from C. arabica Timor Hybrid CIFC 832/2 is reported, which will be a useful tool for future studies on comparative genomics and the identification of genes and regulatory elements controlling major traits in this economically important crop species. Expand
Analysis of alien introgression in coffee tree (Coffeaarabica L.)
TLDR
The results suggested that the transfer of desirable genes from related wild diploid Coffea species into the cultivated allotetraploid C. arabica from C. canephora is not limited by the ploidy level differences or the suppression of recombination between the different genomes. Expand
Gene introgression into Coffea arabica by way of triploid hybrids (C. arabica × C. canephora)
TLDR
A strong deficiency in the C. canephroa alleles is revealed indicating a severe counter-selection against the introgression of genetic material from C. arabica by way of triploid hybrids, which could be an advantage by facilitating the recovery of the recurrent parent and possibly reducing the number of required backcrosses. Expand
The origin of cultivated Coffea arabica L. varieties revealed by AFLP and SSR markers
TLDR
Polymorphism among the subspontaneous accessions was much higher than among the cultivated accessions, confirming the historical documentation on their dissemination of C. arabica from its primary centre of diversity. Expand
Introgression into the allotetraploid coffee (Coffea arabica L.): segregation and recombination of the C. canephora genome in the tetraploid interspecific hybrid (C. arabica×C. canephora)
TLDR
The hybrid (C. arabica×C. canephora 4x) hybrids conformed to the expected ratio assuming random chromosome segregation and the absence of selection, and appeared particularly favourable to intergenomic recombination events and gene introgressions. Expand
Analysis of genetic structure in a sample of coffee (Coffea arabica L.) using fluorescent SSR markers
TLDR
This type of analysis provides a strong evidence of population structure in C. arabica and is possible to better identify a balanced sample of diverse plants in germplasm, which allows the selection of genotypes for association mapping. Expand
Molecular analysis of introgressive breeding in coffee (Coffea arabica L.)
TLDR
Analysis of genetic relationships among the Timor Hybrid-derived genotypes suggested that introgression was not restricted to chromosome substitution but also involved chromosome recombinations, and AFLP seemed to be an extremely efficient technique for DNA marker generation in coffee as well as for the detection of introgressed genotypes.

The ability of C. kapakata to cross with C. arabica was analysed in the present paper. The ratios between seed-ovules, seedling-seeds and seedling-ovules were taken into account in order to evaluate… Expand
Phylogenetic analysis of chloroplast DNA variation in Coffea L.
TLDR
Phylogenetic relationships inferred from the cpDNA analysis suggest several major clades, which present a strong geographical correspondence, and several inconsistencies are observed among taxa endemic to west Africa, suggesting the occurrence of introgressive hybridization. Expand
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. Expand
Genetic resources of Coffea
TLDR
In this chapter, the genetic resources of Coflea will be considered and the specificity of genetic resource studies and their utilisation in coffee breeding are considered. Expand
Relationship between parental chromosomic contribution and nuclear DNA content in coffee interspecific hybrids
TLDR
There was a linear relationship between the number of PSE chromosomes and the nuclear DNA content and this result allows flow cytometry to give a rough estimate of the parental chromosomic contribution in coffee interspecific hybrids. Expand

Haploid plants were found in progenies of the following varieties of Coffea arabica : typica, bourbon, maragogipe, semperflorens, laurina, erecta, caturra and San Ramon; they are reduced in size, their branches are more slender and the leaves are narrower and thinner. Expand
