Karyotype Analysis of Gazania rigens Varieties

open access: yesHorticultural Plant Journal, 2016
For studying species origin, systematic evolution and phylogenetic relationship of Gazania rigens, four different G. rigens varieties, with different flower colors, were subjected to chromosome karyotype analysis.

Karyological comparisons of the European hare (Lepus europaeus Pallas, 1778) from the Asian part of Turkey, with morphological contributions [PDF]

open access: yesArchives of Biological Sciences, 2012
We focused on a comparison of karyological data for the European brown hare Lepus europaeus, from the Asian part of Turkey. In Turkish L. europaeus, the diploid number (2n), the fundamental number of chromosomal arms (FN) and the number of autosomal ...

Scallop genome provides insights into evolution of bilaterian karyotype and development

open access: yesNature Ecology &Evolution, 2017
Reconstructing the genomes of bilaterian ancestors is central to our understanding of animal evolution, where knowledge from ancient and/or slow-evolving bilaterian lineages is critical. Here we report a high-quality, chromosome-anchored reference genome

The wax gourd genomes offer insights into the genetic diversity and ancestral cucurbit karyotype

open access: yesNature Communications, 2019
The botanical family Cucurbitaceae includes a variety of fruit crops with global or local economic importance. How their genomes evolve and the genetic basis of diversity remain largely unexplored.

Karyotype stability and unbiased fractionation in the paleo-allotetraploid Cucurbita genomes

open access: yesbioRxiv, 2017
The Cucurbita genus contains several economically important species in the Cucurbitaceae family. Interspecific hybrids between C. maxima and C. moschata are widely used as rootstocks for other cucurbit crops. We report high-quality genome sequences of C.

Spermatogenesis and nucleolar activity in Triatoma klugi (triatomine, Heteroptera)

open access: yesGenetics and Molecular Biology, 2008
Triatoma klugi is a Chagas disease vector in the Rio Grande do Sul State. Triatominae chromosomes are holocentric and sex chromosomes segregation is post-reductional. In this paper we describe the karyotype of male T.

Pneumocystis carinii karyotypes [PDF]

open access: yesJournal of Clinical Microbiology, 1990
Pulsed-field gel electrophoresis techniques were used to examine the chromosomes of Pneumocystis carinii isolated from laboratory rats and two human subjects. P. carinii organisms isolated from each of four rat colonies and from two patients each produced a distinct band pattern, but in all cases the bands ranged in size from 300 to 700 kilobase pairs.

Dynamic turnover of centromeres drives karyotype evolution in Drosophila

open access: yesbioRxiv, 2019
Centromeres are the basic unit for chromosome inheritance, but their evolutionary dynamics is poorly understood. We generate high-quality reference genomes for multiple Drosophila obscura group species to reconstruct karyotype evolution.

Genome Size Diversity in Lilium (Liliaceae) Is Correlated with Karyotype and Environmental Traits

open access: yesFrontiers in Plant Science, 2017
Genome size (GS) diversity is of fundamental biological importance. The occurrence of giant genomes in angiosperms is restricted to just a few lineages in the analyzed genome size of plant species so far. It is still an open question whether GS diversity

An extraordinarily stable karyotype of the woody Populus species revealed by chromosome painting.

open access: yesThe Plant Journal, 2019
The karyotype represents the basic genetic make-up of a eukaryotic species. Comparative cytogenetic analysis of relative species based on individually identified chromosomes has been conducted only in few plant groups, not yet in woody plants.
