Pelecyphora chihuahuensis (Britton & Rose) D. Aquino & Dan. Sánchez: A Review on Its Taxonomy, Ecology and Conservation of an Endemic Mexican Cactus Species with Biotechnological Perspectives

The cactus <i>Pelecyphora chihuahuensis</i> is endemic to northern Mexico and represents an interesting subject on the integration of classical taxonomy with modern biotechnological tools to solve conservation issues. Because of its narrow ecological range and high ornamental value, the species is increasingly at risk from degradation of its habitats, climate change, and plant poaching. This review includes current knowledge on its taxonomic status, ecological distribution, and conservation needs, with a focus on biotechnological means to aid its preservation. Aspects such as molecular markers, next-generation sequencing, and previously reported GIS-based species distribution models provide valuable insights into its identity and ecological niche. Biotechnological tools for <i>ex situ</i> conservation include <i>in vitro</i> propagation and cryopreservation. Potential applications of CRISPR-Cas and synthetic biology in preserving rare cacti are also discussed. By uncovering gaps, this review opens a window of opportunity to urgently promote the sustainable management of <i>P. chihuahuensis</i> and related endangered cacti by merging biotechnology with ecology and taxonomy, the results presented here underscore the importance of integrating scientific findings into future research that supports the development and implementation of effective policies that prioritize the conservation and biocultural preservation of arid-land flora, ensuring that both ecological integrity and cultural values are maintained for these unique ecosystems.
