Abstract This study is focused on the Tehuacán-Cuicatlán Valley (Oaxaca, Mexico), which has a high diversity of Opuntia species whose phylogenetic relationships and chromosome numbers are mostly unknown. We aimed to investigate the phylogenetic position of Opuntia tehuacana and its sympatric species and to analyze the ploidy levels in fve O. tehuac...
Background: Hybridization in nature occurs in numerous botanical families. In particular, the Cactaceae family contains lots of genera in which hybridization is reported. Questions: What are the patterns of reported natural hybridization in Cactaceae and their probable causes? Are there phylogenetic and evolutionary implications related to hybridi...
Pilosocereus is one of the Cactaceae family’s most relevant genera in terms of the number of species and its wide geographical range in the Americas. Within Pilosocereus , five informal taxonomic groups have been recognized, one of which is P. leucocephalus group s.s. , whose phylogenetic relationships remain unresolved. Therefore, our objectives a...
The process of hybridization occurs in approximately 40% of vascular plants, and this exchange of genetic material between non-conspecific individuals occurs unequally among plant lineages, being more frequent in certain groups such as Opuntia (Cactaceae). This genus is known for multiple taxonomic controversies due to widespread polyploidy and pro...
The Neotropical genus Tillandsia (Bromeliaceae) is an excellent model system for macroevolutionary and biogeographic studies due to its remarkable species diversity (ca. 650 spp.) and varied morphological and ecological adaptations to epiphytic and saxicolous habitats. Recent phylogenetic studies have greatly improved our knowledge about generic li...
El principal objetivo de mi proyecto es saber si Opuntia tehuacana es de origen hibrido, utilizando marcadores moleculares del cloroplasto y núcleo asi como evidencias morfologicas y redes de haplotipos
