“…Genomic changes have been reported in A. tequilana Weber not only in micropropagated plants, but also in those propagated through natural asexual processes (Torres- Morán et al 2010). Asexual genetic variability has also been reported in A. fourcroydes (Infante et al 2003) and A. cupreata Trel et Berger (Martínez-Palacios et al 2011). Another important aspect is to check the regenerative ability of callus tissues through time as has been reported in Sansevieria cylindrica Bojer ex Hook.…”

“…In some reports, it was evident that the genetic fidelity among propagated plants was very high, and few polymorphisms have been reported (Gil-Vega et al 2001). However, Infante et al (2003) reported the presence of asexual genetic variation in A. fourcroydes, and this type of variation has been observed in A. tequilana (Torres-Morán et al 2006.…”

Agave tequilana is a species of great economic importance for the Mexican society. Like most agaves, it can be propagated either sexually or asexually. However, plants originating from rhizomes are mainly used for commercial production. The aim of this study was to determine the genetic fidelity of plants that were obtained from the field and propagated from rhizomes and of those propagated by in vitro culture methods (somatic embryogenesis and proliferation of axillary buds). We used an inverse ISTR (sequence-tagged repeat) molecular marker based on retrotransposon sequences to detect variability among related individual plants. Cluster analysis showed that plants could be grouped according to the propagation method employed. Plants propagated by the same in vitro method were found to be distinct from those propagated in the field. Even within each method, plants were not genetically identical. Genomic changes were evidenced not only in plants subjected to somaclonal variation in vitro but were also evident in those propagated through the natural asexual process, despite the fact that they were considered true clones. The differences observed in plants confirm the existence of asexual genetic variability.

“…Inverse Sequence Tagged Repeats (ISTR) is a molecular marker based on retrotransposons, using encoded reverse transcriptase sequences bounded by copia-like elements. ISTR has showed to be a worthy molecular tool to detect intrapopulation variability in economically important cultivars of coffee, soya, Agave tequilana, Agave fourcroydes and Agave cocui [21][22][23][24][25][26] . In this study the molecular characterization of eight species of Agavaceae (Furcraea sp.…”
