DOI: 10.1002/bit.28289
Abstract: Chinese hamster ovary (CHO) cells are major host cells for biopharmaceuticals. During culture, the chromosome number of CHO cells alters spontaneously. Here, we investigated the effects of artificial changes in the chromosome number on productivity.… read more here.

DOI: 10.1007/s10265-017-0959-8
Abstract: Chromosome number and genome size are important cytological characters that significantly influence various organismal traits. We investigated chromosome number and genome size variation in 73 accessions belonging to four Colocasia species from China. Five different… read more here.

DOI: 10.1016/j.ympev.2019.03.006
Abstract: Large-scale changes in chromosome number have been associated with diversification rate shifts in many lineages of plants. For instance, several ancient rounds of polyploidization events have been inferred to promote genomic differentiation and/or isolation and,… read more here.

DOI: 10.1093/aob/mcac027
Abstract: BACKGROUND AND AIMS It is unclear how widespread polyploidy is throughout the largest holocentric plant lineage-the Cyperaceae. Because of the prevalence of chromosomal fusions and fissions which affect chromosome number but not genome size, it… read more here.

DOI: 10.1101/2025.02.05.636704
Abstract: Activation of synthetic centromeres on chromosome 4 in maize leads to its breakage and formation of trisomic fragments called neochromosomes. A limitation of neochromosomes is their low and unpredictable transmission rates due to trisomy. Here… read more here.

The Role of Meiotic Drive in Chromosome Number Disparity Between Heterosporous and Homosporous Plants
Sign Up to like & getrecommendations! Published in 2025 at "Molecular Ecology"
DOI: 10.1111/mec.17757
Abstract: In vascular plants, heterosporous lineages typically have fewer chromosomes than homosporous lineages. The underlying mechanism causing this disparity has been debated for over half a century. Although reproductive mode has been identified as critical to… read more here.

DOI: 10.3389/fpls.2022.807302
Abstract: The mechanisms controlling chromosome number, size, and shape, and the relationship of these traits to genome size, remain some of the least understood aspects of genome evolution. Across vascular plants, there is a striking disparity… read more here.
