Food Chem 2024; 456:140013. [PMID: 38878536 DOI: 10.1016/j.foodchem.2024.140013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2024] [Revised: 06/04/2024] [Accepted: 06/06/2024] [Indexed: 07/24/2024]
Abstract
Wild Fragaria resources exhibit extensive genetic diversity and desirable edible traits, such as high soluble solid content and flavor compounds. However, specific metabolites in different wild strawberry fruits remain unknown. In this study, we characterized 1008 metabolites covering 11 subclasses among 13 wild diploid resources representing eight species, including F. vesca, F. nilgerrensis, F. viridis, F. nubicola, F. pentaphylla, F. mandschurica, F. chinensis, and F. emeiensis. Fifteen potential metabolite biomarkers were identified to distinguish fruit flavors among the 13 diploid wild Fragaria accessions. A total of nine distinct modules were employed to explore key metabolites related to fruit quality through weighted gene co-expression module analysis, with significant enrichment in amino acid biosynthesis pathway. Notably, the identified significantly different key metabolites highlighted the close association of amino acids, sugars, and anthocyanins with flavor formation. These findings offer valuable resources for improving fruit quality through metabolome-assisted breeding.

Abstract
Plant-endophytic microbes affect plant growth, development, nutrition, and resistance to pathogens. However, how endophytic microbial communities change in different strawberry plant compartments after Fusarium pathogen infection has remained elusive. In this study, 16S and internal transcribed spacer rRNA amplicon sequencing were used to systematically investigate changes in the bacterial and fungal diversity and composition in the endophytic compartments (roots, stems, and leaves) of healthy strawberries and strawberries with Fusarium wilt, respectively. The analysis of the diversity, structure, and composition of the bacterial and fungal communities revealed a strong effect of pathogen invasion on the endophytic communities. The bacterial and fungal community diversity was lower in the Fusarium-infected endophytic compartments than in the healthy samples. The relative abundance of certain bacterial and fungal genera also changed after Fusarium wilt infection. The relative abundance of the beneficial bacterial genera Bacillus, Bradyrhizobium, Methylophilus, Sphingobium, Lactobacillus, and Streptomyces, as well as fungal genera Acremonium, Penicillium, Talaromyces, and Trichoderma, were higher in the healthy samples than in the Fusarium wilt samples. The relative abundance of Fusarium in the infected samples was significantly higher than that in the healthy samples, consistent with the field observations and culture isolation results for strawberry wilt. Our findings provide a theoretical basis for the isolation, identification, and control of strawberry wilt disease.

Physicochemical Quality, Polyphenol Profiles, and Postharvest Performance of Florida Pearl ® 'FL 16.78-109' White Strawberries Compared to the Red Cultivar 'Florida Brilliance'. Foods 2023; 12:3143. [PMID: 37685076 PMCID: PMC10487069 DOI: 10.3390/foods12173143] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2023] [Revised: 08/16/2023] [Accepted: 08/17/2023] [Indexed: 09/10/2023] Open
Abstract
White-fruited strawberry cultivars have recently become popular due to their exotic appearance and flavor, but more needs to be known about their overall quality and postharvest performance. The objective of this study was to characterize and compare the overall quality of the white-fruited strawberry Florida Pearl® 'FL 16.78-109' against the commercial, red-fruited strawberry 'Florida Brilliance' at harvest and during cold storage (1 °C). Results showed that harvest date and weather conditions contributed to significant differences in fruit quality, regardless of the cultivar. However, Pearl was softer at harvest and had lower total phenolic and anthocyanin contents but was less acidic and had higher total sugars and ascorbic acid contents than Brilliance. Pearl major polyphenols were kaempferol 3-glucoside, quercetin 3-glucoside, quercetin, and gallic acid, while for Brilliance epicatechin, pelargonidin, pelargonidin 3-glucoside, and ferulic acid were the major polyphenol compounds identified. After cold storage, Pearl lost less weight than Brilliance and showed a less dramatic decline in individual polyphenols. Pearl and Brilliance anthocyanins and phenolic acids were the polyphenol groups most affected by cold storage because they showed the highest decline from harvest to the end of storage. Cold storage also had different effects on other polyphenols, but the effect was cultivar-dependent. Overall, white strawberries have a unique appearance, are sweet, have an excellent bioactive profile, and can maintain good postharvest quality.
