“…For both years, ANC were identified as the most abundant phenolic compounds in blueberry fruit followed by PA, whereas F3L were the least abundant metabolites (Supplementary Table S2, Supplementary Figure S2A). These results are consistent with other studies 18,20,48,52,53 . The presence of significant genotypic effects controlling phenolic metabolite concentration and fruit quality traits in blueberry has been reported 16,18,22,23,54,55 .…”

“…To quantify phenolics including ANC and non-ANC, commercially cultivated blueberries (unknown variety) were purchased at a local store in Kannapolis, NC (Supplementary Table S1). The composition was consistent with previous reports 18,20,21,48,49 . Among phenolics, ANC accounted for 283 mg/100 g FW within the form of simple glycosides (-3-O-galactoside (Galc), -3-O-glucoside (Gluc) and -3-O-arabinoside (Arab)) in relative abundance of malvidin (Mal) > petunidin (Pet) > cyanidin (Cyan) > peonidin (Peo) > delphinidin (Del).…”

“…1). Results of broad sense heritability estimates were consistent with our previous findings 18 , that raw concentration of phenolic metabolites and fruit quality traits such as ANC, F3L, TSS and fruit weight have moderate to high (> 50%) broad sense heritability. This is the first study that estimates broad sense heritability of flavonoid and PA relative and absolute bioaccessibility in blueberry.…”

“…3). Previous studies have reported a positive association between flavonoids and TSS 18,23,54,55 . This is not surprising since TSS is mainly composed of sugar molecules, and sugar molecules are the major structural component of flavonoid glycosides.…”

In the present study, we applied a novel high-throughput in vitro gastrointestinal digestion model to phenotype bioaccessibility of phenolics in a diverse germplasm collection representing cultivated highbush blueberries. Results revealed significant (P < 0.05) differences between accessions, years, and accession by year interaction for relative and absolute bioaccessibility of flavonoids and phenolic acids. Broad sense heritability estimates revealed low to moderate inheritances of relative and absolute bioaccessibility, suggesting that besides environmental variables, genetics factors could control bioaccessibility of phenolics. Acylated anthocyanins had significantly higher relative bioaccessibility than non-acylated anthocyanins. Correlation analysis indicated that relative bioaccessibility did not show significant association with fruit quality or raw concentration of metabolites. The study also identified accessions that have high relative and absolute bioaccessibility values. Overall, combining the bioaccessibility of phenolics with genetic and genomic approaches will enable the identification of genotypes and genetic factors influencing these traits in blueberry.
