“…Mississippian culture of southeastern and midwestern United States) from around 1600 BCE and between 1000 and 1550 CE, respectively, Smith (2010). Moreover, cultural connections between Mesoamerica and Sonora exist since prehispanic times (Watson and García, 2016) and pinpoint Western Mexico (Jalisco, Nayarit, Colima, and Michoacán) as a macro-regional economy connecting Mesoamerica and the United States Southwest by both coastal and highland routes (Wilcox et al, 2008). Evidence for diffusion of plants along these routes is better understood in maize, whose introduction to the United States Southwest from Mesoamerica began around 2000 BCE, via the highland route, and 2000 years ago, via the coastal route (da Fonseca et al, 2015).…”

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
