Population genetic structure, introgression, and hybridization in the genus Rhizophora along the Brazilian coast
Mangrove plants comprise plants with similar ecological features that have enabled them to adapt to life between the sea and the land. Within a geographic region, different mangrove species share not only similar adaptations ...
Detection of hybrids and genetic introgression in wild stocks of two catfish species (Siluriformes: Pimelodidae): The impact of hatcheries in Brazil
(Elsevier B.V., 2012-08-01)
Molecular markers (Multiplex-PCR and PCR-RFLP of nuclear and mitochondrial genes) were used to assess the frequency of hybrids in wild stocks of two catfish species: Pseudoplatystoma corruscans and Pseudoplatystoma ...
Introgression of the Kinetoplast DNA: An Unusual Evolutionary Journey in Trypanosoma cruzi
(Bentham Science Publishers, 2017)
Introduction: Phylogenetic relationships between different lineages of Trypanosoma cruzi, the agent of Chagas disease, have been controversial for several years. However, recent phylogenetic and phylogenomic analyses ...
Hybridization and introgression across different ploidy levels in the Neotropical orchids Epidendrum fulgens and E-puniceoluteum (Orchidaceae)
(WILEY-BLACKWELL PUBLISHING, INC, 2010)
The hypothesis of gene flow between species with large differences in chromosome numbers has rarely been tested in the wild, mainly because species of different ploidy are commonly assumed to be reproductively isolated ...
Molecular Cytogenetics in Lilium Breeding
(Society for Horticultural Science, 2014)
Genetic identification of interspecific hybrid of Neotropical catfish species (Pseudoplatystoma corruscans vs. Pseudoplatystoma reticulatum) in rivers of Mato Grosso do Sul State, Brazil
(Soc Brasileira Ictiologia, 2014-07-01)
Hybrids of the species Pseudoplatystoma corruscans vs. Pseudoplatystoma reticulatum are extensively traded because they are more docile and precocious compared to their parents. This study aimed to identify the occurrence ...
Distribution of the Bari-I transposable element in stable hybrid strains between Drosophila melanogaster and Drosophila simulans and in Brazilian populations of these species
(Sociedade Brasileira de Genética, 2007-01-01)
We analyzed the distribution of the Bari-I transposable element in Drosophila melanogaster (IN(1)AB), its sibling species Drosophila simulans (C167.4) and in eight hybrid strains derived from initial crosses involving D. ...
Phylogeny of Potamogeton (Potamogetonaceae) revisited: implications for hybridization and introgression in Argentina
(National Science Museum, 2016-11-22)
Potamogeton is a cosmopolitan genus of 90–95 species in which numerous hybridization events have occurred worldwide. A plant recently collected from Argentina exhibited ambiguous morphology that does not match any species ...
Persistence of sunflower crop traits and fitness in Helianthus petiolaris populations
(Wiley Blackwell Publishing, Inc, 2011-09)
Transgenic plants have increased interest in the study of crop gene introgression in wild populations. Genes (or transgenes) conferring adaptive advantages persist in introgressed populations, enhancing competitiveness of ...
