Dynamic patterns of repeats and retrotransposons in the centromeres of Humulus lupulus L. [PDF]

New Phytol
Summary The centromere has a conserved function across eukaryotes; however, the associated DNA sequences exhibit remarkable diversity in both size and structure. In plants, some species possess well‐defined centromeres dominated by tandem satellite repeats and centromeric retrotransposons, while others have centromeric regions composed almost entirely ...

Sensory discrimination of single hop beers by using sorting combined with profiling and intensity rating

Journal of Sensory Studies, Volume 38, Issue 4, August 2023., 2023
Abstract Sensory methodologies are continuously being optimized based on industry needs. Sorting is a widely used sensory method; however, it provides limited information about the uniqueness of individual products. The present work was performed on nine single‐hop beers using a combination of sorting with profiling and intensity rating (SPIR) rating ...
