Kinetochore size correlates with chromosome size in Star of Bethlehem (Ornithogalum kochii Parl., Asparagaceae)

open access: yesPlant Biology, Volume 28, Issue 5, Page 1737-1742, August 2026.
Cytogenetic quantification of KNL1‐labelled kinetochores in Ornithogalum kochii reveals a significant positive scaling relationship between chromosome size and kinetochore size, demonstrating that chromosome–kinetochore scaling operates even across moderate intra‐karyotype size variation.
