Abstract
Karyotype changes are a formidable evolutionary force by directly impacting cross-incompatibility, gene dosage, genetic linkage, chromosome segregation, and meiotic recombination landscape. These changes often arise spontaneously and are commonly detected within plant lineages, even between closely related accessions. One element that can influence drastic karyotype changes after only one (or few) plant generations is the alteration of the centromere position, number, distribution, or even its strength. Here, we briefly explore how these different centromere configurations can directly result in karyotype rearrangements, impacting plant reproduction and meiotic recombination.
期刊介绍：
New Phytologist is an international electronic journal published 24 times a year. It is owned by the New Phytologist Foundation, a non-profit-making charitable organization dedicated to promoting plant science. The journal publishes excellent, novel, rigorous, and timely research and scholarship in plant science and its applications. The articles cover topics in five sections: Physiology & Development, Environment, Interaction, Evolution, and Transformative Plant Biotechnology. These sections encompass intracellular processes, global environmental change, and encourage cross-disciplinary approaches. The journal recognizes the use of techniques from molecular and cell biology, functional genomics, modeling, and system-based approaches in plant science. Abstracting and Indexing Information for New Phytologist includes Academic Search, AgBiotech News & Information, Agroforestry Abstracts, Biochemistry & Biophysics Citation Index, Botanical Pesticides, CAB Abstracts®, Environment Index, Global Health, and Plant Breeding Abstracts, and others.
