Coffee (Coffea canephora) [PDF]

, 2003
#Coffea canephora# possède l'une des aires de répartition les plus larges du sous-genre #Coffea# : elle s'étend d'ouest en est, de la Guinée au Soudan et, du nord au sud, du Cameroun à l'Angola. La conservation à long terme de cette espèce s'effectue en champs à cause du comportement peu orthodoxe de ses graines lors de leur stockage.

Differential regulation of caffeine metabolism in Coffea arabica (Arabica) and Coffea canephora (Robusta) [PDF]

Planta, 2014
Caffeine is a metabolite of great economic importance, especially in coffee, where it influences the sensorial and physiological impacts of the beverage. Caffeine metabolism in the Coffea species begins with the degradation of purine nucleotides through three specific N-methyltransferases: XMT, MXMT and DXMT.
