Rodriguez P. E., Sader M. A., Costa L., Almeida E., Félix L. P., Carvalho-Sobrinho J., Loureiro J., Leitch I. J., Souza G., Why do tropical plants often have smaller genomes? Genome size evolution in Cactaceae is shaped by geographically structured polyploidy, Botanical Journal of the Linnean Society, 2026, 211(3):301-313, doi: 10.1093/botlinnean/boaf064
The study compares genome size, polyploidy and cactus distribution. New measurements include cultivated Leuenbergeria bleo, accounting for endoreduplication in tissue selection.
