Reappraisal of sectional taxonomy in Musa (Musaceae)
Taxon, 2013Co-Authors: Markku HäkkinenAbstract:The present work is part of a continuing study on Musa taxa by the author. Several molecular analyses support accep- tance of only two Musa sections, M. sect. Musa and M. sect. Callimusa. Musa sect. Rhodochlamys is synonymized with M. sect. Musa and M. sect. Australimusa and M. sect. Ingentimusa are treated as synonyms of M. sect. Callimusa. Species lists are provided for the two accepted sections.

Identity of a Pisang - historical concepts of Musa (Musaceae) and the reinstatement of Musa troglodytarum
2012Co-Authors: Markku Häkkinen, Henry Väre, Maarten J. M. ChristenhuszAbstract:Considerable taxonomic confusion surrounds some obviously similar taxa of the genus Musa (Musaceae): M. coccinea, M. fehi, M. seemannii, M. uranoscopos (of various authors), and M. troglodytarum. All these names have been used extensively in Musa literature. All the taxa share an erect or curved inflorescence.

Lectotypification of two Musa sections (Musaceae)
Nordic Journal of Botany, 2009Co-Authors: Markku HäkkinenAbstract:The present work is part of a continuing study to revise the old names in Musa and aims to clarify the taxonomy in the sections Rhodoclamys and Callimusa. Lectotypes are designated here for Musa sect. Callimusa and M. sect. Rhodochlamys. These sections were first erected without the indication of a type species.

Musa chunii Häkkinen, a new species (Musaceae) from Yunnan, China and taxonomic identity of Musa rubra
Journal of Systematics and Evolution, 2009Co-Authors: Markku HäkkinenAbstract:The center of diversity of the genus Musa (Musaceae) is in Southeast Asia, a region not studied in detail and where new species and varieties continue to be reported. A new wild banana species, M. chunii Hakki- nen from Yunnan, China is described and illustrated based on observed morphological characteristics in the field. This extremely rare new species was only found in Tongbiguan Nature Reserve, Dehong District, West Yunnan. A key to M. chunii and related taxa is provided. In addition, critical notes regarding M. rubra Kurz identity are given.

Genome-Wide Analysis of Repeat Diversity across the Family Musaceae
PloS one, 2014Co-Authors: Petr Novák, Eva Hřibova, Jaroslav Doležel, Pavel Neumann, Andrea Koblížková, Jiří MacasAbstract:Background The banana family (Musaceae) includes genetically a diverse group of species and their diploid and polyploid hybrids that are widely cultivated in the tropics. In spite of their socio-economic importance, the knowledge of Musaceae genomes is basically limited to draft genome assemblies of two species, Musa acuminata and M. balbisiana. Here we aimed to complement this information by analyzing repetitive genome fractions of six species selected to represent various phylogenetic groups within the family. Results Low-pass sequencing of M. acuminata, M. ornata, M. textilis, M. beccarii, M. balbisiana, and Ensete gilletii genomes was performed using a 454/Roche platform. Sequence reads were subjected to analysis of their overall intra- and inter-specific similarities and, all major repeat families were quantified using graph-based clustering. Maximus/SIRE and Angela lineages of Ty1/copia long terminal repeat (LTR) retrotransposons and the chromovirus lineage of Ty3/gypsy elements were found to make up most of highly repetitive DNA in all species (14–34.5% of the genome). However, there were quantitative differences and sequence variations detected for classified repeat families as well as for the bulk of total repetitive DNA. These differences were most pronounced between species from different taxonomic sections of the Musaceae family, whereas pairs of closely related species (M. acuminata/M. ornata and M. beccarii/M. textilis) shared similar populations of repetitive elements. Conclusions This study provided the first insight into the composition and sequence variation of repetitive parts of Musaceae genomes. It allowed identification of repetitive sequences specific for a single species or a group of species that can be utilized as molecular markers in breeding programs and generated computational resources that will be instrumental in repeat masking and annotation in future genome assembly projects.

a multi gene sequence based phylogeny of the Musaceae banana family
BMC Evolutionary Biology, 2011Co-Authors: Pavla Christelova, Edmond De Langhe, Miroslav Valarik, Eva Hřibova, Jaroslav DoleželAbstract:The classification of the Musaceae (banana) family species and their phylogenetic inter-relationships remain controversial, in part due to limited nucleotide information to complement the morphological and physiological characters. In this work the evolutionary relationships within the Musaceae family were studied using 13 species and DNA sequences obtained from a set of 19 unlinked nuclear genes. The 19 gene sequences represented a sample of ~16 kb of genome sequence (~73% intronic). The sequence data were also used to obtain estimates for the divergence times of the Musaceae genera and Musa sections. Nucleotide variation within the sample confirmed the close relationship of Australimusa and Callimusa sections and showed that Eumusa and Rhodochlamys sections are not reciprocally monophyletic, which supports the previous claims for the merger between the two latter sections. Divergence time analysis supported the previous dating of the Musaceae crown age to the Cretaceous/Tertiary boundary (~ 69 Mya), and the evolution of Musa to ~50 Mya. The first estimates for the divergence times of the four Musa sections were also obtained. The gene sequence-based phylogeny presented here provides a substantial insight into the course of speciation within the Musaceae. An understanding of the main phylogenetic relationships between banana species will help to fine-tune the taxonomy of Musaceae.

evolutionary dynamics and biogeography of Musaceae reveal a correlation between the diversification of the banana family and the geological and climatic history of southeast asia
New Phytologist, 2016Co-Authors: Steven B Janssens, Filip Vandelook, Edmond De Langhe, Brecht Verstraete, Erik Smets, Ines Vandenhouwe, Rony SwennenAbstract:Tropical Southeast Asia, which harbors most of the Musaceae biodiversity, is one of the most species-rich regions in the world. Its high degree of endemism is shaped by the region's tectonic and climatic history, with large differences between northern Indo-Burma and the Malayan Archipelago. Here, we aim to find a link between the diversification and biogeography of Musaceae and geological history of the Southeast Asian subcontinent. The Musaceae family (including five Ensete, 45 Musa and one Musella species) was dated using a large phylogenetic framework encompassing 163 species from all Zingiberales families. Evolutionary patterns within Musaceae were inferred using ancestral area reconstruction and diversification rate analyses. All three Musaceae genera - Ensete, Musa and Musella - originated in northern Indo-Burma during the early Eocene. Musa species dispersed from 'northwest to southeast' into Southeast Asia with only few back-dispersals towards northern Indo-Burma. Musaceae colonization events of the Malayan Archipelago subcontinent are clearly linked to the geological and climatic history of the region. Musa species were only able to colonize the region east of Wallace's line after the availability of emergent land from the late Miocene onwards.
