Updating the maize karyotype by chromosome DNA sizing
(Plos One, 2018)
Chromosomal location and distribution of As51 satellite DNA in five species of the genus Astyanax (Teleostei, Characidae, Incertae sedis)
(Wiley-Blackwell, 2009-08-01)
Constitutive heterochromatin makes up a substantial portion of the genome of eukaryotes and is composed mainly of satellite DNA repeating sequences in tandem. Some satellite DNAs may have been derived from transposable ...
Chromosomal Mapping of Repetitive DNAs in the Grasshopper Abracris flavolineata Reveal Possible Ancestry of the B Chromosome and H3 Histone Spreading
(2013-06-27)
Supernumerary chromosomes (B chromosomes) occur in approximately 15% of eukaryote species. Although these chromosomes have been extensively studied, knowledge concerning their specific molecular composition is lacking in ...
Chromosome polymorphism in Astyanax fasciatus (Teleostei, Characidae). 2 – Chromosomal location of a satellite DNA
(Cytogenetic and Genome Research, 2018)
Karyotype variability in tropical maize sister inbred lines and hybrids compared with KYS standard line
(Frontiers Research Foundation, 2015)
Structural and functional evidence that a B chromosome in the characid fish Astyanax scabripinnis is an isochromosome
(Blackwell Science, 2000-07-01)
Astyanax scabripinnis possesses a widespread polymorphism for metacentric B chromosomes as large as the largest chromosome pair in the A complement. on the basis of C-banding pattern, it was hypothesized that these B ...
Network genealogy of 195-bp satellite DNA supports the superimposed hybridization hypothesis of Trypanosoma cruzi evolutionary pattern
(Elsevier B.V., 2010-07-01)
Trypanosoma cruzi is highly diverse genetically and has been partitioned into six discrete typing units (DTUs), recently re-named T. cruzi I-VI. Although T. cruzi reproduces predominantly by binary division, accumulating ...
In situ hybridization of bat chromosomes with human (TTAGGG)n probe, after previous digestion with Alu I
(Sociedade Brasileira de Genética, 2002-01-01)
The purpose of this work was to verify the ability of the enzyme Alu I to cleave and/or remove satellite DNA sequences from heterochromatic regions in chromosomes of bats, by identifying the occurrence of modifications in ...
Tracking the evolution of sex chromosome systems in Melanoplinae grasshoppers through chromosomal mapping of repetitive DNA sequences
(2013-08-13)
Background: The accumulation of repetitive DNA during sex chromosome differentiation is a common feature of many eukaryotes and becomes more evident after recombination has been restricted or abolished. The accumulated ...
Chromosome Evolution in African Cichlid Fish: Contributions from the Physical Mapping of Repeated DNAs
(Karger, 2010-01-01)
Cichlid fishes have been the subject of increasing scientific interest because of their rapid adaptive radiation that has led to extensive ecological diversity and because of their enormous importance to tropical and ...
