Flower evocation takes place when meristems became committed to differentiate in reproductive instead of vegetative organs under the lead of environmental signals. For coffee plants in the south-south-eastern Brazil those signals were predicted to be temperature and day-length [1]. Genes FLC/M and VRN are recognized for their roles in model plant flower evocation driven by temperature. FLC/M are major suppressors when flowering do not occur without vernalization. By their turn, VRN genes keep FLC chromatin methylated, to allow flowering. Aiming to verify how coffee orthologs are involved in flower evocation, semi-quantitative analyses in late and early C. arabica were accomplished.
