Bitter fruit: Inverse associations between PTC and Antidesma bunius perception.

Abstract
Ability to perceive the bitter compound phenylthiocarbamide (PTC) is inherited via a dominant "taster" allele of the TAS2R38 gene, while inability is inherited via a recessive "non-taster" allele. This raises a question: Is the non-taster allele functionless, or does it mediate perception of compounds other than PTC? New evidence supports speculation that it is indeed functional. Associations between TAS2R38 mutations and bitter sensitivity to the tropical berry Antidesma bunius are the inverse of those PTC, suggesting that the non-taster allele enables perception to compounds in the fruit.
