Analysis of composition, morphology, and biosynthesis of cuticular wax in wild type bilberry (Vaccinium myrtillus L.) and its glossy mutant

In this study, cuticular wax load, its chemical composition, and biosynthesis, was studied during development of wild type (WT) bilberry fruit natural glossy (GT) mutant. GT load comparable with WT fruits. both, the proportion triterpenoids decreased concomitant increasing proportions total aliphatic compounds. fruit, a higher in accompanied by lower fatty acids ketones compared to as well density crystalloid structures on berry surfaces. Our results suggest that phenotype could be caused absence rod-like associated reduction wax. Especially CER26-like, FAR2, CER3-like, LTP, MIXTA, BAS genes showed skin preferential expression patterns indicating their role biosynthesis secretion.
