Understanding the extensive hybridization in South American Nothofagus through karyotype analysis
(Oxford University Press, 2018-07)
Extensive phylogeographic and population studies in Nothofagus revealed that hybridization, introgression and plastid capture are common phenomena that have occurred throughout the evolutionary history of the genus. Here, ...
Karyotype stability and genome-specific nucleolar dominance in peanut, its wild 4× ancestor, and a synthetic AABB polyploid
(Crop Science Society of America, 2018-07)
Allopolyploidy is a significant evolutionary process involved in the origin of many crops, including peanut (Arachis hypogaea L.). The process usually results in a series of chromosome, genomic and epigenetic rearrangements ...
Incipient speciation in Calceolaria polyrhiza complex (Calceolariaceae): Cytogenetic analysis supports molecular and morphological data
(Taylor & Francis Ltd, 2021-06)
Calceolaria polyrhiza is a perennial herb distributed in southern South America. The species is highly polymorphic and includes four described morphotypes that were previously considered different species. We performed a ...
Primates sin frontera: una visión desde la citogenética evolutiva
(Sociedad Argentina de Genética, 2010-12)
Estudiar las características de variabilidad genética, organización social y biogeografía, permite nuevas interpretaciones del proceso especiogénico. En Primates en particular, en los 80, se desarrollan los primeros estudios ...
A chromatin code for alternative splicing involving a putative association between CTCF and HP1aα proteins
(BioMed Central, 2015-12-02)
Background: Alternative splicing is primarily controlled by the activity of splicing factors and by the elongation of the RNA polymerase II (RNAPII). Recent experiments have suggested a new complex network of splicing ...
Chromosome variability and evolution in rodents of the tribe abrotrichini (rodentia, cricetidae, sigmodontinae)
(Springer Research Institute, 2019-11-30)
Rodents are a very diverse group with large chromosome variability. One of the most species rich linage in the Neotropics is the Sigmodontinae. Among them, the tribe Abrotrichini was recently defined and its taxonomy and ...
Chromosome evolution in Cophomantini (Amphibia, Anura, Hylinae)
(Public Library of Science, 2018-02)
The hylid tribe Cophomantini is a diverse clade of Neotropical treefrogs composed of the genera Aplastodiscus, Boana, Bokermannohyla, Hyloscirtus, and Myersiohyla. The phylogenetic relationships of Cophomantini have been ...
New insights into the six decades of Mesa’s hypothesis of chromosomal evolution in Ommexechinae grasshoppers (Orthoptera: Acridoidea)
(Wiley Blackwell Publishing, Inc, 2021-12)
In Acridoidea grasshoppers, chromosomal rearrangements are frequently found as deviations from the standard acrocentric karyotype (2n = 23♂/24♀, FN = 23♂/24♀) in either phylogenetically unrelated species or shared by closely ...
Chromosome evolution in Cophomantini (Amphibia, Anura, Hylinae)
