Cyperaceae in Mexico: Diversity and distribution
Botanical Sciences, 2018 Background: Cyperaceae, with about 5,500 species and 90 genera worldwide, are the third largest family among Monocots. A unique combination of morphological and karyotypical features, among which stand holokinetic chromosomes, favors a rapid evolution ...

Fluorescence in situ hybridization to chromosomes as a tool to understand human and primate genome evolution [PDF]
, 2005 For the last 15 years molecular cytogenetic techniques have been extensively used to study primate evolution. Molecular probes were helpful to distinguish mammalian chromosomes and chromosome segments on the basis of their DNA content rather than solely ...

Specific nuclear envelope transmembrane proteins can promote the location of chromosomes to and from the nuclear periphery [PDF]
, 2013 BACKGROUND: Different cell types have distinctive patterns of chromosome positioning in the nucleus. Although ectopic affinity-tethering of specific loci can be used to relocate chromosomes to the nuclear periphery, endogenous nuclear envelope proteins ...

Disease-associated patterns of disomic chromosomes in hyperhaploid neoplasms.
, 2012 The chromosome number of human tumors varies widely, from near-haploidy to more than decaploidy. Overt hyperhaploid (24-34 chromosomes) tumors constitute a small minority (0.2-0.3% of cytogenetically investigated lesions), but occur in many different ...
