<i>In vitro</i> Mutagenesis for the Improvement of Agave Genus

Biotechnological techniques provide a viable alternative to help improve and increase the production of plant species of agricultural and economic importance, which have been affected over the years by climate change, increasing their susceptibility to pests and/or diseases, generating losses in production as well as a decrease in their regenerative and genetic diversity. The application of biotechnological techniques such as in vitro mutagenesis offers a viable option for the generation of crops that are resistant to the different factors caused by abiotic and biotic stress. In vitro mutagenesis has been used in an efficient way to generate genetic changes in different plant species. However, these methods have not been studied thoroughly in crops of agro-industrial interest, such as agave, which represents an economic resource of national importance and are considered as endemic species of Mexico. Therefore, this literary review aimed to focus on the studies that have been used for the genetic improvement of this species via mutagenesis techniques in plants in the agave genus. Therefore, the objective was to set a precedent for future genetic studies that aim to obtain more productive regenerants for various industries, such as food and pharmaceutical. It is also of great interest to compile information from basic research that helps understand and elucidate a model of possible defense mechanisms that are activated in the Agave genus.
