RESUMO
Agaves are cultivated in Mexico as a source of industrial products such as fibers, nutritional supplements, and alcoholic beverages. Due to the demand for plant material, its long-life cycle, and the need to avoid predation on its natural populations, in vitro micropropagation represents a good option for agaves. Plant tissue culture has been successfully used to micropropagate selected elite individuals from plants of various Agave species of economic interest. However, it is necessary to implement systems that lower production costs without losing the quality of the plantlets obtained. This chapter describes the BioMINT™ bioreactor as an alternative for the micropropagation of agaves in the different stages of the micropropagation process.

Agave fourcroydes (henequén) is a plant used for the extraction of hard fiber from its leaves. Due to its long-life cycle, it is very difficult to genetically improve. Somatic embryogenesis (SE) is a very useful micropropagation technique, that can be used for genetic improvement programs and increase the micropropagation of this species. SE is a morphogenic process by which somatic embryos are generated from somatic cells reprogramming. To initiate the regeneration program, the loss of cell-cell communication is suggested to be important. The Thin Cell Layer (TCL) technique allows for the isolation of specific cell or tissue layers, and in conjunction with strictly controlled growth conditions, may lead to the in vitro induction of specific morphogenic programs. Here, we describe a new protocol for the induction of somatic embryogenesis through TCL culture technique, from stem of elite clonal A. fourcroydes vitroplants previously generated through micropropagation of adventitious shoots.
