Sugar production levels and protein profiles of Mangifera indica were examined in order to study their relationship during development. Sugar levels were analyzed over eight developmental stages using an ATAGO hand refractometer. The results showed that sugar was detected at stage two and remained at the same level through stage five, increased at stage six and seven, and reached a maximum at stage eight. Protein profiles, determined by proteomics, indicated 98 variably expressed proteins. These were found to respond to stress (16%), signal (13%), transport (11%), respiration (4%), carbohydrate metabolisms (8%), lipid metabolisms (6%), protein metabolisms (3%), secondary metabolisms (2%), cell division (3%), ripening (1%), transcription (28%) and translation (5%). Eleven proteins showed a similar trend in expression to sugar production suggesting an involvement in the development of sweetness.
