| Abstract:
Banana and plantain (Musa species, Zingiberales) are a relatively under researched plant group in contrast to their great socio-economic importance and their significance as one of the earliest domesticated crops. The classification of species and clones is hampered by the traditional morphology-based taxonomy, with limited knowledge on specific molecular characteristics of individual taxons. The phylogeny of the Musaceae has never been fully resolved, and the accuracy of the current classification system is a common point of debate among the scientific community. Different types of molecular markers have been used to investigate the diversity at various taxonomic levels within Musa species and have reached various degrees of success in terms of phylogenetic reconstruction. The phylogenetic history of Musaceae as a part of the order Zingiberales was investigated in previous studies (Kress et al., 2001). However, within the family Musaceae itself, few papers have addressed this question (Lescot et al., 2008; Boonruangrod et al., 2008) and the evolutionary relationships remain fuzzy. This paper is an overview of molecular-based approaches that have been employed by our research group in an attempt to shed more light on Musaceae diversity and evolutionary relationships, and thereby serve for the classification and development of reliable markers for unambiguous banana species identification. | |
