“…planifolia, V. pompona y V. odorata fueron las especies con mayor número de presencias, y se encontraron en siete de los nueve estados de la República Mexicana donde se distribuye el género, esto debido principalmente a su semidomesticación en el manejo de su cultivo. Dos de estas tres especies presentan gran demanda en la industria (Reyes-López et al, 2008;Soto, 2009;Azofeifa-Bolaños et al, 2014), V. inodora y V. insignis se encontraron en cinco estados de México, mientras que V. sprucei y V. cribbiana solo se registraron en el estado de Chiapas, resultados que coinciden con lo reportado por Soto y Dressler (2010). Lubinsky et al (2008), mencionan que los cultivos de V. planifolia y V. pompona se originaron en México, probablemente en el norte de Veracruz.…”

“…Dentro de este género, Vanilla planifolia, Vanilla pompona y Vanilla tahitensis son las especies más importantes en el mundo, por ser productoras de vainillina natural Álvarez et al, 2013;Azofeifa-Bolaños, Paniagua-Vásquez, & García-García, 2014). La vainillina es considerada la sustancia aromatizante y saborisante más importante, con mayor valor económico en el mercado (Divakaran, Nirmal, & Peter, 2006;Pérez-Silva et al, 2006;Pérez, Günata, Lepoutre, & Odoux, 2011).…”

Diversity and bioclimatic profiles of Vanilla spp. (Orchidaceae) in Mexico. The genus Vanilla comprises around 110 species distributed throughout Earth's tropical regions, with the largest number of reported species growing in the American continent. Vanilla farming is associated with many Mexican cultures such as the Totonac, Mayan, Chinantec, and Mazatec, among others. Currently, this crop is threatened by technical, social, ecological, and climatic conditioning factors, limiting its production and the preservation of wild and cultivated species. It is therefore necessary to ascertain the current diversity status of each of these species, as well as some of their main bioclimatic profile indicators, in order to help decision-making, aimed at preserving and genetically improve these species. During 2008, we gathered data from IPN, MEXU, and XAL herbaria, as well as from CONABIO's World Information Network on Biodiversity (REMIB), the Global Biodiversity and Information Facility (GBIF), and we also used data from live access to BUAP's vanilla germplasm bank, obtained between 2008 and 2014. Distribution maps were generated using a geographical information system. Bioclimatic profiles for each species were obtained considering 19 WorldClim variables and altitude at a spatial resolution of approximately 1 Km 2 . Variance, Mean, and standard deviation for each of the 19 variables were calculated at each of the registered points. Extreme environmental condition intervals (minimum, average, and maximum) were also obtained. In order to determine the most important distribution variables of the species, we performed a principal component analysis and carried out Kruskal-Wallis and Dunn's tests on the variables identified as significant. Results indicated records for V. planifolia, V. pompona, V. insignis, V. inodora V. odorata, V. cribbiana, and V. sprucei in Mexico, distributed throughout nine states in the country. V. planifolia presented wide intervals of temperature and rain precipitation, while V. pompona, V. odorata, V. insignis and V. inodora presented intermediate intervals. The amplitudes of extreme data for each species can be considered in locating areas where ex situ regional preservation strategies could be put in place, as well as in establishing areas for cultivation. The bioclimatic profile we found, allows for an indirect inference of each species' genetic condition, which could be used in genetic improvement programs; for instance, V. odorata grows at high altitudes and tolerates low temperatures, while V. inodora tolerates high temperatures, and V. odorata, V. pompona and V. planifolia tolerate low rain precipitation.

“…This vacuum ranges from basic biology including aspects of its systematics, phylogenetics, ecology, and physiology through more applied aspects such as the conservation status of its species (Gigant et al 2011, HerreraCabrera et al 2012, Azofeifa-Bolaños et al 2014). At the most basic level, the identity, distribution, and circumscription of Vanilla taxa constitute the cornerstone to addressing problems related to the successful conservation and sustainable exploitation of the species of the genus.…”

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. Se realizó una inferencia filogenética con ITS. Resultados: Los ISSR discriminaron claramente a los individuos si...

“…During surveys carried out in Costa Rica since 2012 (Azofeifa-Bolaños et al 2014) abundant populations of vanilla which did not fit any species previously described in the country were observed in Limón Province (Caribbean coast of Costa Rica). This vanilla, called "vanilla Limón" (VanL), had strong morphological similarities with a vanilla accession collected in Cahuita (Limón, Costa Rica) in 1993, referenced Pignal 396b (P00075132) in the herbarium of the Muséum national d'Histoire naturelle in Paris, P (herbarium acronym following Thiers continuously updated).…”
