Chromosome Evolution in New World Monkeys (Platyrrhini) [PDF]

open access: yes, 2012
During the last decades, New World monkey (NWM, Platyrrhini, Anthropoideae) comparative cytogenetics has shed light on many fundamental aspects of genome organisation and evolution in this fascinating, but also highly endangered group of neotropical ...

Colchicine-induced autotetraploidy and altered plant cytogenetic and morpho-physiological traits in Catharanthus roseus (L.) G. Don

open access: yesAdvances in Horticultural Science, 2018
Artificially induced polyploidy is often used to alter plant growth pattern and genetic makeup of certain plant species. This experiment was conducted to induce autotetraploidy in Catharanthus roseus (‘Alba’) which contains diploid chromosomes ...

chromploid: An R package for chromosome number evolution across the plant tree of life. [PDF]

open access: yesAppl Plant Sci, 2018
Premise of the Study Polyploidy has profound evolutionary consequences for land plants. Despite the availability of large phylogenetic and chromosomal data sets, estimating the rates of polyploidy and chromosomal evolution across the tree of life remains

Copy number variation, chromosome rearrangement, and their association with recombination during avian evolution [PDF]

open access: yes, 2010
Chromosomal rearrangements and copy number variants (CNVs) play key roles in genome evolution and genetic disease; however, the molecular mechanisms underlying these types of structural genomic variation are not fully understood.
