“…Agave plants are characterized by short stems with leaves organized in rosettes, with different levels of succulence, fibrous and with a terminal spine, their edges may have thorns [3]. The lifecycle in this genus varies among species, but normally it takes around 5 to 20 years before producing a paniculate or racemose inflorescence in the subgenus Agave and a spicate inflorescence in the Littae subgenus [4].…”

The Agave genus is composed of approximately 210 species distributed from south United States to Colombia and Venezuela. Numerous Agave species have been used for the preparation of alcoholic beverages and have attracted interest in the pharmaceutical and food industry. Despite their economic importance, there are few initiatives for the improvement and selection of characteristics of interest. This is mainly due to its morphology, long lifecycles, and monocarpic nature. Micropropagation is a feasible alternative to the improvement of Agave species. It has been used for multiple purposes, including massive propagation, induction of somaclonal variation to enhance agronomic characteristics of interest, maintenance of specific genotypes, and genetic transformation using molecular techniques. In this report, we summarize the most outstanding findings regarding the micropropagation of Agave species mediated by multiple regeneration responses. We also describe the media and growth regulators for each of the previously described methods. In addition, we discuss how micropropagation has allowed the development of transformation protocols. Exploitation of this technology may be a feasible strategy to introduce genes and improve certain traits. Genetic transformation also offers an opportunity for studying molecular mechanisms. This represents advantages for optimizing production in the field and for implementing breeding programs.

“…Agave L. es un género americano cuyos representantes nativos se distribuyen desde el sur de los Estados Unidos de América hasta Venezuela, Colombia, Ecuador, Perú y el Caribe (Gentry, 1982;García-Mendoza, 2007, 2011Giraldo-Cañas, 2020). Este género presenta aproximadamente 265 especies (Thiede, 2020), siendo México el centro de mayor riqueza y endemismo (García-Mendoza et al, 2019), particularmente en el valle de Tehuacán-Cuicatlán en la región limítrofe entre los estados de Oaxaca y Puebla (Thiede, 2020).…”

“…The Agave genus is endemic to the Americas and comprises at least 206 species. Mexico is the primary center of diversity for this genus, as approximately 75% (159) of Agave species occur in its territory [ 7 , 8 ]. Agaves are economically important plants in Mexico because they are a source of many products, such as food, fiber, construction materials, and beverages, to mention some [ 7 , 9 ].…”

Despite the recognition of Agave tequilana Weber var. Azul as raw material for producing tequila and obtaining prebiotics, there are other highly relevant Agave species in Mexico. Oaxaca contains a startlingly diverse range of Agave species; Agave angustifolia Haw. and Agave potatorum Zucc. are two classic specimens with great commercial potential. In this study, we examined the fructan fluctuation in these two species during their lifetime in the field (from 1 to 6 years old). First, we analyzed their morphological diversity based on vegetative characteristics. Subsequently, fructan extracts were analyzed by TLC, FT-IR, and HPAEC-PAD to identify carbohydrates. Multivariate analyses of the morphological parameters indicated a morphological divergence between the two species. Furthermore, we found that the concentration of simple carbohydrates and fructans, as well as the fructan DP, changed during plant development. Glucose, fructose, and fructooligosaccharides (FOS) were more abundant in A. potatorum, while A. angustifolia showed a greater amount of sucrose and fructans with a high DP. Fructan DP heatmaps were constructed using HPAEC-PAD profiles—the heatmaps were very helpful for establishing an easy correlation between age and the carbohydrate types present in the fructan extracts. This study is an important contribution to the agave fructan knowledge of the Mexican agave diversity.
