In this study the Italian garlic "Aglio di Vessalico" was compared with the French cultivars Messidrome and Messidor, whose cloves are used every year by the growers of Vessalico (Imperia, Italy) for sowing, and with the geographically adjacent "Aglio di Caraglio". UHPLC-Q-trap analyses of the extracts of these commercial garlic accessions showed similar profiles for sulfur compounds, highlighting the presence of typical molecules of stored garlic. HC, PCA and SOM, applied to the LC/MS data, allowed to separate the garlic accessions, confirming similarities between Vessalico and French accessions, while Caraglio formed a more compact group. All garlic extracts showed ability to deactivate Tomato brown rugose fruit virus (ToBRFV) infectivity, as a possible conse-quence of disassembly of the virus coat protein (CP). Molecular docking showed a strong interaction of the sulfur compounds characteristic of aged extracts with a high number of residues into ToBRFV CP binding site, inter-fering with virulence progress.

Abstract

In this study the Italian garlic "Aglio di Vessalico" was compared with the French cultivars Messidrome and Messidor, whose cloves are used every year by the growers of Vessalico (Imperia, Italy) for sowing, and with the geographically adjacent "Aglio di Caraglio". UHPLC-Q-trap analyses of the extracts of these commercial garlic accessions showed similar profiles for sulfur compounds, highlighting the presence of typical molecules of stored garlic. HC, PCA and SOM, applied to the LC/MS data, allowed to separate the garlic accessions, confirming similarities between Vessalico and French accessions, while Caraglio formed a more compact group. All garlic extracts showed ability to deactivate Tomato brown rugose fruit virus (ToBRFV) infectivity, as a possible conse-quence of disassembly of the virus coat protein (CP). Molecular docking showed a strong interaction of the sulfur compounds characteristic of aged extracts with a high number of residues into ToBRFV CP binding site, inter-fering with virulence progress.
