Hop plant – from history through omics to beer

Original language description

PATZAK, Josef. Hop plant – from history through omics to beer. Bulletin ČSEBR a Fyziologické sekce SBS 1/2023: 116, 2023. Hop (Humulus lupulus L.) is a diploid, dioecious, perennial climbing plant belonging to the Cannabaceae family. Female plants are cultivated for the commercial production of inflorescences (cones), which are mainly used in the brewing industry but also commonly used in the production of pharmaceuticals and cosmetics. In the early Middle Ages, wild and cultivated hops were found in many parts of central and northern Europe and they have been used for the preparation of beer since the ninth century. The names of traditional landrace cultivars refer to the regions and places of origin from this time. Saaz and Hersbruck landraces were historically the most important for genetic diversity of European wild hops. The active transfer of Saaz hop plants in Europe took place in the 14th century and subsequently also in the 19th century. A recent technical advance in next generation sequencers (NGS) opened a way to obtain huge amounts of transcriptome and whole genome sequence information, which together with proteome studies have provided a systematic understanding of secondary metabolite biosynthesis pathways, the role of structural and regulatory genes for their biosynthesis in lupulin glands (glandular trichomes). Unique and exclusive organs predominantly formed in hop cone inflorescence. From our results, we confirmed that the bitter acid content in lupulin glands is dependent on the last step of alpha bitter acid biosynthesis and lupulin gland density. We also studied gene expressions of transcription factors involved in regulatory network for secondary metabolite biosynthesis and lupulin glands development. New Omics information can be useful for hop breeders because beer market, mainly craft breweries, is seeking for new hop cultivars with new flavours. Moreover, big brewery groups are afraid of climate changes to keep sustainable hop production and hop breeding is necessary to overcome these abiotic and biotic factors by new more tolerant cultivars.
