“…While the Maya area seems to be where vanilla was first used, it is only recently (in the last 20 years) that Maya vanilla has been produced for international export (Schlüter et al 2007). Earlier diffusions of Maya vanilla were precluded by geographic disadvantage; namely, the relative inaccessibility to overseas markets from the forested, tropical interior.…”

Origins and Dispersal of Cultivated Vanilla (Vanilla planifolia Jacks. [Orchidaceae]).Vanilla is a clonally propagated crop originating from Mesoamerica. Information regarding the circumstances under which vanilla cultivation began is incomplete. Presumably, the Totonac people of Papantla (north-central Veracruz, Mexico) were the earliest to cultivate vanilla; however, the oldest reports of vanilla use relate to the pre-Columbian Maya of southeastern Mexico/Central America, where vanilla was a cacao-beverage spice. We utilized Amplified Fragment Length Polymorphism (AFLP) marker diversity to infer the origins and relationships among cultivated and non-cultivated vanilla in Mesoamerica and on islands in the Indian Ocean, which comprise today's principal production regions of vanilla. Our results suggest that, genetically, vanilla cultivated outside of Mesoamerica is most closely related to cultivated stock from Papantla; whereas unique clones of V. planifolia are found in non-cultivated and cultivated individuals from elsewhere in Mesoamerica. This is consistent with a single origin for cultivated vanilla outside of Mexico, along with multiple origins for cultivated material within Mexico. These data suggest that vestiges of pre-Columbian Maya vanilla cultivars are not found in commercial production today.

“…However, a clear picture of its distribution is still uncertain (Soto-Arenas 1999) because relatively few wild individuals have apparently been collected (fewer than 30 individuals, according to Soto-Arenas 2006 andSchlüter et al 2007). There are also several vegetatively similar species.…”

“…In the Mexican Yucatan Peninsula (MYP), wild individuals of Vanilla planifolia have been collected, but only a few of them have been included in previous studies of this species (Cibrián 1999, Schlüter et al 2007. Furthermore, at least four additional species of the genus have been reported as growing actually or potentially sympatrically with V. planifolia in this region: Vanilla insignis, Vanilla odorata, Vanilla inodora Schiede, and Vanilla sp.…”

Background: Vanilla planifolia, a threatened species, is distributed naturally in semi-deciduous and evergreen rain forests of southeastern Mexico and parts of Central America. In the wild, it is difficult to diagnose from another sympatric Vanilla species, and individuals with reproductive structures are usually required. Questions: Can ISSR discriminate wild individuals of Vanilla planifolia from other sympatric species of the genus? Can phylogenetic analyses of ITS recover the monophyly of V. planifolia and help identify Vanilla species? Studied species: The vanilla (V. planifolia), the second-most important economically spice in the world. Study site and years of study: Plant material was collected during 2014 in the Mexican Yucatan Peninsula. Methods: We analyzed 88 wild individuals of several Vanilla species. Individuals of five species of Vanilla reported for the region were used as reference. 84 ISSR loci were analyzed using three clustering methods. A phylogenetic inference using ITS was performed. Results: ISSR markers clearly discriminate wild Vanilla planifolia, finding definite genetic structure within the species. The three clustering methods identified genetic relationships with congruent patterns. Five groups were found and they corresponded with the species studied. Phylogenetic inference of ITS sequences supported the monophyly of the Vanilla and the resulting cladograms were coherent with the clustering pattern observed in the ISSR studies. Conclusions: Both ISSR and ITS analyses are able to identify V. planifolia. Molecular data suggest the presence of V. pompona and a new species of Vanilla in the Yucatan Peninsula. Keywords: Genetic identification, molecular markers, phylogenetic analysis, vanilla, wild populations.Vanilla planifolia silvestre y sus parientes en la Península de Yucatán, México: análisis sistemáticos con ISSR e ITS Resumen Antecedentes: Vanilla planifolia es una especie amenazada que se distribuye naturalmente en las selvas tropicales perennifolias y subperennifolias del sureste de México y parte de Centroamérica. En estado silvestre, es difícil de diferenciar de otras especies simpátricas de Vanilla, y usualmente se requieren individuos con estructuras reproductivas. Preguntas: ¿Pueden los marcadores ISSR discriminar individuos silvestres de Vanilla planifolia de otras especies simpátricas de vainilla?, ¿Puede el análisis de ITS recobrar la monofilia de V. planifolia y contribuir a identificar las especies de Vanilla? Especie en estudio: Económicamente, la vainilla (Vanilla planifolia) es la segunda especia más importante en el mundo. Sitio de estudio y fecha: La colecta se realizó en 2014 en la Península de Yucatán. Métodos: Se analizaron 88 de individuos silvestres de especies de Vanilla. Se utilizaron como testigos individuos de cinco especies de vainilla reportadas para la región. 84 loci de ISSR fueron analizados usando tres métodos de agrupamiento.

Además pobres manejos del cultivo ocasionan la pér-dida de material genético valioso (Soto, 1999;Bory et al, 2008), presión de selección sobre la especie V. planifolia, destrucción de hábitats por causas humanas y meteorológicas, carencia de cultivares mejorados de las especies económicamente importantes, problemas fitosanitarios en monocultivos y cambios climáticos (Divakaran et al, 2006).…”

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 and conservation of the Vanilla genus in Costa Rica. Topics covered in this study were: taxonomy in the country and worldwide, data collection and new estimates of wild relatives, the economic, ecological and social importance, the gene pool of the Costa Rican species, the crop situation worldwide (harvested area, production, yield, major producers), causes that reduce the productive potential of the species, culture methods, the vulnerability of Vanilla planifolia to extinction, and the genetic potential in the country with respect to the concentration of vanillin. The comprehensive conservation strategy proposed in this paper aims to perpetuate vanilla plant genetic resources in gene banks through a formal system of seed production, for further use for breeding, research and commercial production. Through sustainable use, those species will be protected in Costa Rica. The natural or legal persons who use such materials must generate monetary or non-monetary benefits from the use of resources through a fair and equitable system to the suppliers. Agro-ecological conditions of Costa Rica as well as the genetic material of both wild and cultivated vanilla opens the possibility of developing production models based on organic agriculture.
