Metabolic response of peach fruit to invasive brown marmorated stink bug (Halyomorpha halys Stål.)’s infestation [Elektronski vir]Gačnik, Saša, agronom, 1994- ; Rusjan, Denis ; Mikulič Petkovšek, MajaThe brown marmorated stink bug (BMSB; Halyomorpha halys Stål.) is a highly destructive and polyphagous invasive pest that poses a serious threat to more than a hundred reported host plants. In the ... current study, the metabolic response of peach fruit of two cultivars—‘Maria Marta’ and ‘Redhaven’—to BMSB infestation was studied using high-performance liquid chromatography (HPLC) and mass spectrometry (MS). In general, a strong phenolic response to BMSB infestation in peach flesh in the injury zone was observed, with flavanol content increasing by 2.4-fold, hydroxycinnamic acid content by 5.0-fold, flavonol content by 3.2-fold, flavanone content by 11.3-fold, and dihydrochalcones content by 3.2-fold compared with the undamaged tissue in the cultivar ‘Maria Marta’. The phenolic response in the ‘Redhaven’ cultivar was even stronger. Consequently, the total phenolic content in the injured flesh also increased, 3.3-fold in ‘Maria Marta’ and 6.9-fold in ‘Redhaven’, compared with the uninjured flesh. Infestation with BMSB induced the synthesis of cyanidin-3-glucoside, which is not normally present in peach flesh. In comparison, the phenolic response was lower in peach peel, especially in the cultivar ‘Maria Marta’. The study showed that both peach cultivars reacted to BMSB infestation with an increase in phenolic content in the peach flesh, but in a limited area of injury.Source: International journal of molecular sciences [Elektronski vir]. - ISSN 1422-0067 (Vol. 25, iss. 1, art. 606, 2024, 17 str.)Type of material - e-article ; adult, seriousPublish date - 2024Language - englishCOBISS.SI-ID - 181059587
