  abstract = {{P}henolic compounds are involved in plant response to environmental conditions and are highly present in leaves of {C}offea arabica {L}., originally an understory shrub. {T}o increase knowledge of {C}. arabica leaf phenolic compounds and their patterns in adaptation to light intensity, mature leaves of {E}thiopian wild accessions, {A}merican pure lines and their relative {F}1 hybrids were sampled in full sun or under 50% shade field plots in {M}exico and at two contrasting elevations in {N}icaragua and {C}olombia. {T}wenty-one phenolic compounds were identified by {LC}-{DAD}-{MS}2 and sixteen were quantified by {HPLC}-{DAD}. {F}our of them appeared to be involved in {C}. arabica response to light intensity. {T}hey were consistently more accumulated in full sun, presenting a stable ratio of leaf content in the sun vs. shade for all the studied genotypes: 1.6 for 5-{CQA}, {F}-dihex and mangiferin and 2.8 for rutin. {M}oreover, 5-{CQA} and mangiferin contents, in full sun and shade, allowed for differentiating the two genetic groups of {E}thiopian wild accessions (higher contents) vs. cultivated {A}merican pure lines. {T}hey appear, therefore, to be potential biomarkers of adaptation of {C}. arabica to light intensity for breeding programs. {W}e hypothesize that low 5-{CQA} and mangiferin leaf contents should be searched for adaptation to full-sun cropping systems and high contents used for agroforestry systems.},
