“…Using morphological characters, Gentry discussed the origin of four cultivars (azul, listado al margen, manso, and pata de mula) as well as A. angustifolia var. espadín from specific wild populations in Mexico (Gentry, 1982) while Valenzuela proposed the identity of four cultivars: sigüín, moraleño, bermejo, and chato (Valenzuela Zapata, 1995). More recently, the phylogenetic relationships between nine A. tequilana cultivars were derived using AFLP markers (Gil-Vega et al, 2006) recognizing three closely related groups: 1) azul, azul listado, sigüín, manso, and moraleño, 2) FIGURE 8 | Effect of mayahuelin from A. tequilana var.…”

“…Historical accounts report the movement of A. salmiana and A. americana from central-(Tlaxcala) to northern-Mexico (Saltillo and Durango), right after the conquest of Mexico by the Spaniards, as thousands of náhuatl-speaking peoples, mainly Tlaxcaltecs, colonized the region bringing with them maguey to maintain their deep-rooted tradition of pulque production (Gentry, 1982). During the XVII century (circa 1621) agaves were already under cultivation in the Tequila region of Jalisco (Valenzuela Zapata, 1995) although historical accounts of their origin are still unknown. It remains to be studied how A. angustifolia var.…”

Agaves resist extreme heat and drought. In A. tequilana var. azul, the central spike of the rosette-containing the shoot apical meristem and folded leaves in early stages of development-is remarkably heat tolerant. We found that the most abundant protein in this organ is a 27 kDa protein. This protein was named mayahuelin to honor Mayáhuel, the agave goddess in the Aztec pantheon. LC-MS/MS analyses identified mayahuelin as a type I RIP (Ribosome Inactivating Protein). In addition to the spike, mayahuelin was expressed in the peduncle and in seeds, whereas in mature leaves, anthers, filaments, pistils, and tepals was absent. Anti-mayahuelin antibody raised against the A. tequilana var. azul protein revealed strong signals in spike leaves of A. angustifolia, A. bracteosa, A. rhodacantha, and A. vilmoriniana, and moderate signals in A. isthmensis, A. kerchovei, A. striata ssp. falcata, and A. titanota, indicating conservation at the protein level throughout the Agave genus. As in charybdin, a type I RIP characterized in Drimia maritima, mayahuelin from A. tequilana var. azul contains a natural aa substitution (Y76D) in one out of four aa comprising the active site. The RIP gene family in A. tequilana var. azul consists of at least 12 genes and Mayahuelin is the only member encoding active site substitutions. Unlike canonical plant RIPs, expression of Mayahuelin gene in S. cerevisiae did not compromise growth. The inhibitory activity of the purified protein on a wheat germ in vitro translation system was moderate. Mayahuelin orthologs from other Agave species displayed one of six alleles at Y76: (Y/Y, D/D, S/S, Y/D, Y/S, D/S) and proved to be useful markers for phylogenetic analysis. Homozygous alleles were more frequent in wild accessions whereas heterozygous alleles were more frequent in cultivars. Mayahuelin sequences from different wild populations of A. angustifolia and A. rhodacantha allowed the

Background and Scope Crassulacean acid metabolism (CAM) is an intriguing physiological adaptation in plants that are widespread throughout many ecosystems. Despite the relatively recent mechanistic understanding of CAM in plant physiology, evidence from historical records suggest that ancient cultures in the Americas also recognized the value of CAM plants. Agave species in particular have a rich cultural legacy that provides a foundation for commercially valued products. Here, we review that legacy and potential relationships between ancient values and the needs of modern-day climate adaptation strategies. Conclusions There are many products that can be produced from Agave spp., including food, sugar, fiber, and medicines. Traditional knowledge about agricultural management and preparation of plant products can be combined with new ecophysiological knowledge and agronomic techniques to develop these resources in the borderland region of the southwest US and Mexico. Historical records of pre-Columbian practices in the Sonoran desert and remnants of centuries-old agriculture in Baja California and Sonora demonstrate the climate resilience of Agave agriculture. Commercial growth of both tequila and bacanora indicates the potential for large-scale production today, but also underscores the importance of adopting regenerative agricultural practice in order to accomplish environmentally sustainable production. Recent international recognition of the Appellation of Origin for several Agave spp. produced for spirits in Mexico may provide opportunities for agricultural diversification. In contrast, fiber is currently produced from several Agave species on many continents. Projections of growth with future climate change suggest that Agave spp. will be viable alternatives for commodity crops that suffer declines during drought and increased temperatures. Historic cultivation of Agave affirms that these CAM plants can supply sugar, soft and hard fibers, medicines, and food supplements.

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.
