Increased maize chromosome number by engineered chromosome fission. [PDF]
Sci AdvActivation 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 we report that selecting for dicentric recombinants through male crosses uncovers stabilized chromosome 4 ...

Karyotype analysis of some Onobrychis (sainfoin) species in Turkey [PDF]
Archives of Biological Sciences, 2012 In this study, karyotype analysis of the species of Onobrychis sp. was undertaken using the squash method. The results showed that the chromosome number of Onobrychis tournefortii (Willd.) Desv., O. gracilis Besser, O. hypargyrea Boiss. is 2n = 14 and

Mechanisms of chromosome number evolution in yeast. [PDF]
PLoS Genetics, 2011 The whole-genome duplication (WGD) that occurred during yeast evolution changed the basal number of chromosomes from 8 to 16. However, the number of chromosomes in post-WGD species now ranges between 10 and 16, and the number in non-WGD species ...
