Across 325 Darwin Tree of Life genomes, satellite-array and transposon-cluster centromeres are phylogenetically scattered, fitting a model of repeated interconversion; satellites share higher-order repeat structure but not sequence.

This study compares holocentromere organization in two Cyperaceae subfamilies, revealing differences in repeat structure and protein distribution associated with centromere function.

The paper identifies repeat-based holocentromeres in Luzula sylvatica and proposes mechanisms for the evolutionary transition from monocentric to holocentric chromosomes.

The paper introduces antibodies against KNL1 and NDC80 as more versatile markers for detecting functional centromeres in plants compared to CENH3 antibodies.

The paper investigates meiotic recombination dynamics in a holocentric plant, finding that telomere-led pairing drives a U-shaped crossover distribution, independent of centromere organisation.

The paper develops oligo-based barcode probes for holocentric chromosomes in Rhynchospora and uses them to analyze karyotype evolution across species.
