An updated explanation of ancestral karyotype changes and reconstruction of evolutionary trajectories to form Camelina sativa chromosomes

open access: yesBMC Genomics, 2020
Background Belonging to lineage I of Brassicaceae, Camelina sativa is formed by two hybridizations of three species (three sub-genomes). The three sub-genomes were diverged from a common ancestor, likely derived from lineage I (Ancestral Crucifer ...

Multidirectional chromosome painting substantiates the occurrence of extensive genomic reshuffling within Accipitriformes. [PDF]

open access: yes, 2015
BACKGROUND: Previous cross-species painting studies with probes from chicken (Gallus gallus) chromosomes 1-10 and a paint pool of nineteen microchromosomes have revealed that the drastic karyotypic reorganization in Accipitridae is due to extensive ...

Characterization of the Arachis (Leguminosae) D genome using fluorescence in situ hybridization (FISH) chromosome markers and total genome DNA hybridization [PDF]

open access: yes, 2008
Chromosome markers were developed for Arachis glandulifera using fluorescence in situ hybridization (FISH) of the 5S and 45S rRNA genes and heterochromatic 4'-6-diamidino-2-phenylindole (DAPI) positive bands.

Phylogenetic inferences of Atelinae (Platyrrhini) based on multi-directional chromosome painting in Brachyteles arachnoides, Ateles paniscus paniscus and Ateles b. marginatus [PDF]

open access: yes, 2005
We performed multi-directional chromosome painting in a comparative cytogenetic study of the three Atelinae species Brachyteles arachnoides, Ateles paniscus paniscus and Ateles belzebuth marginatus, in order to reconstruct phylogenetic relationships ...

FISH-aimed karyotype analysis in Aconitum subgen : aconitum reveals excessive rDNA sites in tetraploid taxa [PDF]

open access: yes, 2018
The location of 5S and 35S rDNA sequences in chromosomes of four Aconitum subsp. Aconitum species was analyzed after fluorescence in situ hybridization (FISH). Both in diploids (2n = 2x = 16; Aconitum variegatum, A. degenii) and tetraploids (2n = 4× = 32;

Cytological features of penaut genome [PDF]

open access: yes, 2017
The genus Arachis is composed of 82 species (Krapovickas and Gregory 1994; Valls and Simpson 2005; Valls et al 2013; Santana and Valls 2015) mainly distributed within a large region of South America, which extends from the eastern foothills of the Andes ...

Karyotype Evolution in Aeshna (Aeshnidae, Odonata) [PDF]

open access: yesHereditas, 2004
The haploid DNA content of Aeshna confusa (2n = 27, n = 13 + XO, male). A. bonariensis (2n = 26, n = 12 + neo-XY, male) and A. cornigera planaltica (2n = 16, n = 7 + neo-XY, male) has been determined (2.16 ± 0.16 pg, 1.81 ± 0.17 pg, and 2.08 ± 0.08 pg, respectively).
