  • Title: In Vitro Propagation of Threatened Agave Species Using a Two-Stage System.
    Author: Chávez Ortiz LI, Pérez Molphe Balch E.
    Journal: Methods Mol Biol; 2024; 2827():165-178. PubMed ID: 38985269.
    Abstract:
    Agaves are plants with multiple possibilities of use and are naturally tolerant to low water availability conditions and high temperatures. This makes them species of great interest in the context of the necessary substitution of crops due to climate change. Unfortunately, the overexploitation of wild specimens has endangered many species of the genus that have not been domesticated or cultivated intensively. In vitro mass culture and propagation techniques have emerged as a very efficient option to produce agave plants that can be used without damage to the natural populations. A protocol is presented here for the in vitro micropropagation of agaves in a two-stage process. In the first step, clusters of slightly differentiated shoots are generated from stem segments cultivated on a semisolid medium added with cytokinin. In a second step, these shoot clusters are cultured in temporary immersion bioreactors where they grow and complete their differentiation, and then the shoots are rooted and transferred to soil. This protocol has been successfully applied to several threatened species of the Agave genus.
