Genetic Analysis of Methyl Anthranilate, Mesifurane, Linalool, and Other Flavor Compounds in Cultivated Strawberry (Fragaria × ananassa)

The cultivated strawberry ( Fragaria × ananassa ) is an economically important fruit crop that intensively bred for improved sensory qualities. diversity of flavors and aromas in results mainly from the interactions sugars, acids, volatile organic compounds (VOCs) are derived diverse biochemical pathways influenced by expression many genes. This study integrates multiomic analyses to identify QTL candidate genes multiple aroma a complex breeding population. Novel was discovered methyl anthranilate, 2-hexenoate, 2-methylbutyrate, mesifurane, shared on Chr 3 found nine monoterpene sesquiterpene compounds, including linalool, 3-carene, ?-phellandrene, ?-limonene, linalool oxide, nerolidol, ?-caryophellene, ?-farnesene, ?-farnesene. Fruit transcriptomes subset 64 individuals were used support gene identification. For esters grape-like novel ANTHANILIC ACID METHYL TRANSFERASE –like identified. Two mesifurane correspond with known biosynthesis O-METHYL 1 FURANEOL GLUCOSYLTRANSFERASE . terpene contains fruit-expressed terpenoid pathway-related NEROLIDOL SYNTHASE FanNES1 ). abundance other monoterpenes partially governed co-segregating expression-QTL (eQTL) transcript variation, there additional evidence quantitative effects terpenoid-pathway this narrow genomic region. These QTLs present new opportunities flavor commercial strawberry.
