Abstract: | Agaves are succulent monocot plants rich in fibers, sugars and other important compounds. They are also valued as ornamental
plants and for their ability to grow in poor soils. In the present study, inverse sequence-tagged repeats (ISTR) and amplified
fragment length polymorphism (AFLP) analysis were used to study genetic diversity in differentAgavaceae plant samples. Comparison of the banding patterns between the mother plant and rhizome-derived daughter plants showed that
genetic variability is generated during asexual reproduction in these species. Phylogenetic relationships amongAgave species were obtained using unweighted pair-group method, arithmetic average (UPGMA) analysis. Genetic diversity through
asexual propagation allows for genetic selection and improvement within these asexually propagated plants. |
