Dynamic patterns of repeats and retrotransposons in the centromeres of Humulus lupulus L.
Original language description
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 of retrotransposons. Using a combination of bioinformatic, molecular, and cytogenetic approaches, we analyzed the centromeric landscape of Humulus lupulus. We identified novel centromeric repeats and characterized two types of centromeric organization. Cytogenetic localization on metaphase chromosomes confirmed the genomic distribution of the major repeats and revealed unique centromeric organization specifically on chromosomes 2, 8, and Y. Two centromeric types are composed of the major repeats SaazCEN and SaazCRM1 (Ty3/Gypsy) which are further accompanied by chromosome-specific centromeric satellites, Saaz40, Saaz293, Saaz85, and HuluTR120. Chromosome 2 displays unbalanced segregation during mitosis and meiosis, implicating an important role for its centromere structure in segregation patterns. Moreover, chromosome 2-specific centromeric repeat Saaz293 is a new marker for studying aneuploidy in hops. Our findings provide new insights into chromosome segregation in hops and highlight the diversity and complexity of the centromere organization in H. lupulus.
