Eggplant (Solanum melongena L.) polyphenol oxidase multi-gene family: a phylogenetic evaluation.

ABSTRACT: Polyphenol oxidases (PPOs) in different Solanum species including eggplant have been studied. PPOs have been implicated in undesirable enzymatic browning of eggplant fruit and also in plant defense. The main objective of this study was to identify and accelerate the further functional characterization of additional eggplant PPOs that are involved in food biochemistry and defense-related functions. Eggplant PPOs identified earlier were used in "Basic local alignment search tool (BLAST)" search against expressed sequence tag and nucleotide databases. We have identified seven additional sequences which were almost complete in length. The sequences of the PPOs were aligned and their phylogenetic and evolutionary relationships established. The sequences are quite diverse, broadly falling into t
