Caption: Citrus greening disease research. Chemist and horticulturalist reviewing data obtained from an 'electronic tongue' that has been used to 'taste' citrus fruits infected with citrus greening disease. Also known as huanglongbing (HLB), this disease causes mottled leaves and small, bitter fruits that remain partly green even when ripe. It is transmitted by the Asian citrus psyllid (Diaphorina citri). There is no cure. This experiment examines chemical differences related to taste to see whether it is possible to distinguish between juice from HLB-infected oranges and from non-infected oranges.
