A hybrid swarm of manatees along the Guianas coastline, a peculiar environment under the influence of the Amazon River plume Anais da ABC (AABC)
LIMA,CAMILLA S.; MAGALHÃES,RAFAEL F.; MARMONTEL,MIRIAM; MEIRELLES,ANA CAROLINA; CARVALHO,VITOR LUZ; LAVERGNE,ANNE; THOISY,BENOIT DE; SANTOS,FABRÍCIO R..
Abstract: The West Indian (Trichechus manatus) and Amazonian (T. inunguis) manatees have a sympatric occurrence at the mouth of the Amazon River. A result of this interspecific encounter is the occurrence of hybrids, which are frequently found along the coasts of Amapá state in Brazil, French Guiana and Guyana. Here we present new genetic evidence indicating the occurrence of a hybrid swarm along the Guianas Shield coastline, which is an interspecific hybrid zone that also separates T. manatus populations located east (Brazil) and west (Caribbean, Gulf of Mexico, Florida and Antilles). In addition, we suggest that this hybrid population occupies a peculiar mangrove-rich environment under strong influence of the Amazon River plume, which requires an...

Can habitat specialisation maintain a mosaic hybrid zone in marine bivalves? ArchiMer
Bierne, Nicolas; David, Pierre; Langlade, Aime; Bonhomme, F.
Maintaining the integrity of differentiated genomes in marine organisms needs efficient isolation mechanisms, because planktonic larval dispersion provides contacts between taxa. Habitat specialisation is interesting in this respect, because it can both prevent interspecific crosses (each taxon reproduces in its own habitat) and eliminate hybrids (typically less fit than a parental taxon in each habitat). The contact zone between smooth-shelled mussels Mytilus edulis and M. galloprovincialis in Europe is a good example, as allozyme genotypes typical of both taxa seem to segregate into different habitats. However, allozymes may be selected directly and it is not known whether the same pattern can be extended to the whole genome. Here, we used 6 presumably...

Cucumber breeding and genomics: Potential from research with Cucumis hystrix National Institute of Agronomic Research
Jin-Feng Chen; Long-Zheng Chen; Yong Zhuang; You-Gen Chen; Xiao-Hui Zhou.
Cucumis hystrix Chakr. (2n=2x=24) is a wild Cucumis species found in Yunnan (China) having cross compatibility with cultivated cucumber (C. sativus L., 2n=2x=14). Since the first interspecific hybridization successfully made in 1995 and development of the synthetic allotetraploid species (C. X hytivus Chen and Kirkbride, 2n=4x=38) in 2000, experiments with C. hystrix and the progenies derived from this interspecific cross were carried out for the potentials in cucumber genetics and cultivar improvements. Some important characters or traits found in C. hystrix were introduced, and the novel germplasm developed from this cross and some results from genetic and epigenetic studies were summarized for the first time in this review. Future objectives are...

Evidence of natural hybridization and introgression in Bulbophyllum involutum Borba, Semir & F. Barros and B. weddellii (Lindl.) Rchb. f. (Orchidaceae) in the Chapada Diamantina, Brazil, by using allozyme markers Rev. Bras. Bot.
Azevedo,Cecília O.; Borba,Eduardo L.; Van Den Berg,Cássio.
Hybridization between B. involutum and B. weddellii (Orchidaceae) has been first observed in the Serra do Cipó, Minas Gerais State, Brazil, the hybrid being described as B. ×cipoense Borba & Semir. In this study, allozime electrophoresis was used to test the hypothesis of occurrence of hybridization between these two species, as suggested by morphological characters, in the Chapada Diamantina, Bahia State, Brazil. The lack of a diagnostic locus does not allow definite confirmation of the natural hybridization, although this hypotheses is reinforced by the absence of exclusive alleles in the putative hybrid individuals. The existence of several different genotypes points out to either population derived from multiple hybridization events or the...

Evolutionary history of the sequestrate genus Rossbeevera (Boletaceae) reveals a new genus Turmalinea and highlights the utility of ITS minisatellite-like insertions for molecular identification Naturalis
Orihara, T.; Lebel, T.; Ge, Z.-W.; Smith, M.E.; Maekawa, N..
The sequestrate (truffle-like) basidiomycete genera Rossbeevera, Chamonixia, and Octaviania are closely related to the epigeous mushroom genera Leccinum and Leccinellum. In order to elucidate the properties and placement of several undescribed sequestrate taxa in the group and to reveal the evolutionary history of Rossbeevera and its allies, we conducted phylogenetic analyses based on three nuclear (ITS, nLSU, EF-1α) and two mitochondrial DNA loci (ATP6 and mtSSU) as well as precise morphological observations. Phylogenetic analyses of three nuclear loci suggest a complex evolutionary history with sequestrate fruiting bodies present in several clades, including a previously unrecognized sister clade to Rossbeevera. Here we propose a new sequestrate genus,...

Genetic identification of interspecific hybrid of Neotropical catfish species (Pseudoplatystoma corruscans vs. Pseudoplatystoma reticulatum) in rivers of Mato Grosso do Sul State, Brazil Neotropical Ichthyology
Vaini,Jussara Oliveira; Grisolia,Alexéia Barufatti; Prado,Fernanda Dotti do; Porto-Foresti,Fábio.
Hybrids of the species Pseudoplatystoma corruscansvs.Pseudoplatystoma reticulatum are extensively traded because they are more docile and precocious compared to their parents. This study aimed to identify the occurrence of hybrid 'Surubim' in rivers of the State of Mato Grosso do Sul, applying molecular techniques. Pseudoplatystoma corruscans, Pseudoplatystoma reticulatum and hybrid 'Surubim' were detected using multiplex PCR and PCR-RFLP in RAG2, GLOBIN, EF1α, 18S rRNA nuclear genes, and mitochondrial 16S rRNA gene. The results revealed the presence of F1 hybrids in rivers and the occurrence of genetic introgression, evidenced by the Post-F1 hybrids. Furthermore, discrepancies between the morphological and genetic identification were observed,...

Hybrids between Pseudoplatystoma corruscans and P. reticulatum (Siluriformes: Pimelodidae) previously reported in the Upper Paraná River are likely escapes from aquaculture farms: evidence from microsatellite markers Rev. Bras. Zool.
Baggio,Rafael A.; Moretti,Caroline B.; Bialetzki,Andréa; Boeger,Walter A..
ABSTRACT The production of hybrids of the 'pintado', Pseudoplatystoma corruscans (Spix & Agassiz, 1829) and 'cachara', Pseudoplatystoma reticulatum (Eigenmann & Eigenmann, 1889) in captivity has generated many concerns about the possibility of introduction of farmed hybrids into natural environments. In the last decade, hybrids between these species, known as 'pintachara' or 'cachapinta', were reported from different regions of the Upper Paraná River basin. Prospection of these hybrids is important in order to orient conservation programs for the species involved. Knowledge of the presence of these hybrids will direct conservation strategies towards prevention and/or mitigation of the effects of cross breeding in natural populations of P....

Morphological and genetic perspectives of hybridization in two contact zones of closely related species of Petunia (Solanaceae) in southern Brazil Acta Botanica
Teixeira,Marcelo C.; Turchetto,Caroline; Hartke,Sara; Schnitzler,Carolina K.; Freitas,Loreta B..
ABSTRACT Interspecific hybridization has several consequences for parental species, from blurring species limits to the emergence of new taxa. Petunia axillaris and P. exserta occur in sympatry in southernmost Brazil and naturally hybridize despite their different pollination syndromes and habitat requirements. We employed genetic and morphological analyses to characterize two contact zones between the species with the aim of determining the effect of interspecific hybridization. Microsatellite loci and a morphometric evaluation of the corolla shape were used to classify individuals based on their origin as pure parental or hybrids. Corolla color was used to classify individuals a priori (white, red or intermediate, for P. axillaris, P. exserta or hybrid,...

The use of single nucleotide polymorphism (SNP) molecular markers has provided advances in selection methodologies used in breeding programs of different crops, reducing cost and time of cultivar release. Despite the great economic and social importance of Coffea arabica, studies with SNP markers are scarce and a small number of SNP are available for this species, when compared with other crops of agronomic mportance. Thus, the objective of this study was to identify and validate SNP molecular markers for the species Coffea arabica and to introduce these markers to genetic breeding by means of an accurate analysis of the diversity and genetic structure of breeding populations of this species. After quality filtering, 11,187 SNP markers were selected from...
