|a The chemical and transcriptional changes in the cuticle of pomegranate (Punica granatum L.) fruit grown under different environmental conditions were studied. We collected fruit from three orchards located in different regions in Israel, each with a distinct microclimate. Fruit were collected at six phenological stages, and cutin monomers in the fruit cuticle were profiled by gas chromatography-mass spectrometry (GC-MS), along with qPCR transcript-expression analyses of selected cutin-related genes. While fruit phenotypes were comparable along development in all three orchards, principal component analyses of cutin monomer profiles suggested clear separation between cuticle samples of young green fruit to those of maturing fruit. Moreover, total cutin contents in green fruit were lower in the orchard characterized by a hot and dry climate compared to orchards with moderate temperatures. The variances detected in total cutin contents between orchards corresponded well with the expression patterns of BODYGUARD, a key biosynthetic gene operating in the cutin biosynthetic pathway. Based on our extraction protocols, we found that the cutin polyester that builds the pomegranate fruit cuticle accumulates some levels of gallic acid-the precursor of punicalagin, a well-known potent antioxidant metabolite in pomegranate fruit. The gallic acid was also one of the predominant metabolites contributing to the variability between developmental stages and orchards, and its accumulation levels were opposite to the expression patterns of the UGT73AL1 gene which glycosylates gallic acid to synthesize punicalagin. To the best of our knowledge, this is the first detailed composition of the cutin polyester that forms the pomegranate fruit cuticle
