Asexual genetic variability in Agavaceae determined with inverse sequence-tagged repeats and amplification fragment length polymorphism analysis
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 different Agavaceae 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 among Agave 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. © 2006 International Society for Plant Molecular Biology.
