The genus Vanilla belongs to the Orchidaceae family and Vanilla planifolia, probably endemic from tropical forests in Eastern Mexico, is the main source for commercial vanilla. There has recently been an important number of publications covering Vanilla taxonomy, particularly using molecular genetics, but the taxonomy of the genus is still unclear and numerous synonyms remain. Recent studies showed that inter-specific hybridization and perhaps even polyploidization played an important role in… Expand

Patterns of introduction and diversification of Vanilla planifolia (Orchidaceae) in Reunion Island (Indian Ocean).
TLDR
The genetic diversity revealed could not explain the phenotypic diversity of Vanilla planifolia, which may be related to epigenetics or polyploidy, but a new understanding of the basis of genetic diversity of vanilla may assist to improve management of genetic resources. Expand
Importancia y desafíos de la conservación de Vanilla spp. (orquidaceae) en Costa Rica
Importance and conservation challenges of Vanilla spp. (Orchidaceae) in Costa Rica. The aim of this work was to describe the importance and the main challenges for the use, management andExpand
Harnessing large-scale biodiversity data to infer the current distribution of Vanilla planifolia (Orchidaceae)
TLDR
Results suggest that V. planifolia has a larger geographical distribution than previously recognized; it is hypothesized that populations naturally dispersed from Mesoamerica and became established in South America (with a south-eastern limit in Brazil). Expand
The extent of genetic diversity among Vanilla species: comparative results for RAPD and ISSR.
TLDR
The first comparative results for RAPD and ISSR reporting inter-relationship among nine cultivated, wild and hybrid Vanilla species are reported, indicating a narrow genetic base. Expand
Metabolic characterization of green pods from Vanilla planifolia accessions grown in La Réunion
Large phenotypic variation has been observed between the cultivated vanillas since a single genetic source of Vanilla planifolia was spread to the Indian Ocean and the Indonesia in the 19th century.Expand

  • Advances in Plant Breeding Strategies: Industrial and Food Crops
  • 2019
TLDR
The establishment of modern Vanilla breeding programs could leverage increasingly accessible technologies including advances in genomics and biotechnology to rapidly improve this species for high priority traits like disease resistance, total bean yield, pod uniformity, vigor, non-splitting pods, flower longevity, extract quality and flowers that are able to self-pollinate without manual intervention. Expand
Development of microsatellite markers in cultivated vanilla: Polymorphism and transferability to other vanilla species
TLDR
This paper describes for the first time the isolation and characterization of 14 microsatellite loci from V. planifolia that were monomorphic within cultivated accessions, as expected from the probable single clonal origin of this crop and previous genetic studies. Expand
Vainillas colombianas y su microbiota. II. Diversidad, cultivo y microorganismos endófitos
TLDR
This study assessed the understanding of vanilla cultivation as well as the diversity of the genus Vanilla in Colombia, and found twenty species of Colombian vanilla and 60 morphospecies of endophytic microorganisms. Expand
Development of species-specific molecular markers in Vanilla for seedling selection of hybrids
TLDR
This study used publicly available sequence data to develop species-specific, qRT-PCR-based molecular markers for Vanilla to validate parentage of hybrid progeny from controlled crosses and supported species assignments for unknown accessions including the detection of putative hybrids. Expand

The primary gene pool of Vanilla planifolia Jackson, the main source for commercial vanilla, is heavily threatened in its area of origin (Central America) by habitat fragmentation and destruction. InExpand
RAPD genetic diversity in cultivated vanilla: Vanilla planifolia, and relationships with V. tahitensis and V. pompona
TLDR
Within the sampling limit of the present study, it was suggested that V. tahitensis is probably not a species of direct hybrid origin ( V. planifolia × V. pompona ) but rather a species related to V.planifolia . Expand
Conservation of Vanilla species, in vitro
TLDR
This synseed and in vitro conservation system can be utilized for conservation and exchange of vanilla genetic resources. Expand
The diversification of Citrus clementina Hort. ex Tan., a vegetatively propagated crop species.
TLDR
The DNA of this type of mobile elements is evolving faster than the DNA of other markers in this clonal lineage, and two geographical distant groups have evolved in agreement with polymorphisms based on IRAP markers anchored to at least, two different Copia-like retrotransposon sequences. Expand
Interspecific differentiation and hybridization in Vanilla species (Orchidaceae)
TLDR
Electrophoresis of seven polymorphic enzymes revealed that the genetic composition of the three species is very similar: they deviate mainly from each other in allele frequencies rather than by specific alleles, suggesting that the species may hybridize. Expand
Patterns of genetic variation in Gymnadenia conopsea, the fragrant orchid
TLDR
The species had high genetic variation within and low genetic divergence among populations, although the correlation between population size and number of alleles was close to significance at the 95% level and a significant isolation by distance effect was observed. Expand

TLDR
It is concluded that Oreja de Burro and Mansa have morphological and phenological characteristics which permit their clear separation. Expand
Domestication of plants in Maya Lowlands
TLDR
Recent evidence on early agriculture in the geographic area where Lowland Maya culture originated is reviewed, and its implications for the study of plant domestication and evolution under human selection within this cultural sub-area are discussed. Expand
Phylogenetic Relationships of Pogoniinae (Vanilloideae, Orchidaceae): An Herbaceous Example of the Eastern North America-Eastern Asia Phytogeographic Disjunction
TLDR
The structure of the cladograms and the high levels of bootstrap support strongly indicate that the genus Cleistes is paraphyletic and this phylogenetic study adds an additional herbaceous example to the growing list of plants that demonstrate this classical biogeographic pattern. Expand
Natural hybridization between Vanilla claviculata (W.Wright) Sw. and V. barbellata Rchb.f. (Orchidaceae): genetic, morphological, and pollination experimental data
TLDR
Data sets support the hypothesis that the individuals are hybrids, which is further augmented by interspecific pollination experiments between the putative parental species and the first case of natural hybridization reported in the genus Vanilla. Expand
