“…Pollination by multiple pollen donors and relatively low biparental inbreeding are also in accordance with the typical low density of plants in wild Arabica coffee populations (Senbeta & Denich, ; Labouisse et al ., ; Schmitt et al ., ; Aerts et al ., ), promoting longer flight distances. Moreover, substantial gene flow between populations of wild Arabica coffee in Ethiopia has been reported (Aga et al ., ; Tesfaye et al ., ).…”

“…The ancestor of cultivated Arabica coffee is wild C. arabica L., a shrub endemic to south‐west Ethiopia (Anthony et al ., , ), where it naturally occurs in the understorey of the Afromontane moist forests. Wild populations of Arabica coffee in these rainforests are genetically diverse, and probably possess desirable traits that can be used to improve the cultivated varieties of C. arabica worldwide (Aga, Bekele & Bryngelsson, ; Aerts et al ., ; Tesfaye et al ., ). At least within Ethiopia, active selection and hybridization activities with wild coffee individuals in recent decades have led to numerous landraces or farmers' varieties (reviewed by Labouisse et al ., ).…”

Coffea arabica, the wild ancestor of all commercial Arabica coffee cultivars worldwide, is endemic to the montane rainforests of Ethiopia. These forests, which harbour the most important C. arabica gene pool, are threatened by increasing anthropogenic disturbance, potentially altering the mating patterns, pollen dispersal and maintenance of genetic diversity in C. arabica understorey populations. We genotyped 376 adult coffee shrubs and 418 progenies from three natural unmanaged, and three highly managed coffee populations, using 24 microsatellite markers. Mating system analysis of C. arabica yielded an overall multilocus outcrossing rate of 76%, which contrasts with the common knowledge that C. arabica is a predominantly selfing species. In highly managed coffee populations, paternity could be assigned to 78% of the progenies, whereas in the unmanaged natural coffee populations, only 57% of the progenies could be assigned to a father, indicating reduced long-distance pollen dispersal in managed forests. Furthermore, the fraction of selfed progenies was significantly higher in managed (23%) than unmanaged (10%) coffee forests. Finally, the lack of spatial genetic structure in all studied populations suggests high seed dispersal in unmanaged populations, and intense berry harvesting and coffee planting in the managed populations. Our results imply that in situ conservation of the wild gene pool of C. arabica must focus on limiting intensification of coffee forest management, as decreased pollen dispersal and increased selfing in C. arabica in intensively managed populations may increase the risk of genetic erosion.

“…Davis, or other staff at the RBG). Numerous genetic analyses ( Tadele et al, 2014 , Tesfaye et al, 2007 , Tesfaye et al, 2014 ) show that Ethiopian cultivated stock is derived directly from the wild C. arabica genepool, with no indications of hybridization with robusta ( C. canephora ), or Arabica cultivars backcrossed with robusta (e.g. Coffee cv.…”

16-O-methylcafestol is present in ground roast Arabica coffees: Implications for authenticity testing

HighlightsLipophilic extracts of ground roast Arabica coffees were authenticated by benchtop NMR.Small amounts of esterified 16-O-methylcafestol were found in Arabica coffees.The compound identity was confirmed by NMR and MS experiments.16-OMC remains a useful marker for non-Arabicas as these contain much higher amounts.6 out of 60 retail Arabicas contained significant amounts of non-Arabica species.

“…It is interesting that wild species do not occur in America, native taxa are found only in Africa and in the South Asian regions [2,9]. They grow in forests at an altitude of 950-2000 m and at 18-22°C, the most favorable altitude being between 1300 and 1600 m [2,3,10]. There are also coffee shrubs, which are cultivated at higher regions, and they are named "high grown" coffee with an outstanding quality [11].…”

Coffea arabica L. is the most well-known and studied Coffea taxa, which is very popular in both scientific and social fields. This comprehensive work was created in order to describe its phytochemical composition and to present the metabolism of caffeine, which is the most important alkaloid from this plant. The analytical methods used for caffeine determination such as chromatographic, electrochemical, and spectroscopic techniques are also presented. In addition, this work emphasizes the medicinal importance of caffeine, which can present both important beneficial and secondary effects for human body.
