Diversity in the genus Musa Focus on Australimusa
نویسنده
چکیده
The Australimusa section is one of the four sections into which the genus Musa is divided (the others being Eumusa, Rhodochlamys and Callimusa). Members of the Australimusa and Callimusa sections have a basic chromosome number of 2n = 20, as opposed to 2n = 22 of Eumusa and Rhodochlamys. There are seven species of Australimusa and a group of parthenocarpic edible types – known as Fe’i bananas – have also evolved within this section. These cultivars are distinguished by their erect bunches and red sap and are found almost exclusively in the Pacific region.

The ITS1-5.8S-ITS2 Sequence Region in the Musaceae: Structure, Diversity and Use in Molecular Phylogeny
Genes coding for 45S ribosomal RNA are organized in tandem arrays of up to several thousand copies and contain 18S, 5.8S and 26S rRNA units separated by internal transcribed spacers ITS1 and ITS2. While the rRNA units are evolutionary conserved, ITS show high level of interspecific divergence and have been used frequently in genetic diversity and phylogenetic studies. In this work we report on ...
متن کاملNuclear genome size and genomic distribution of ribosomal DNA in Musa and Ensete (Musaceae): taxonomic implications.
Nuclear DNA content and genomic distributions of 5S and 45S rDNA were examined in nineteen diploid accessions of the genus Musa representing its four sections Eumusa, Rhodochlamys, Callimusa and Australimusa, and in Ensete gilletii, which was the outgroup in this study. In the Eumusa (x = 11), 2C DNA content ranged from 1.130 to 1.377 pg, M. balbisiana having the lowest DNA content of all secti...
متن کاملGoing Bananas in Papua New Guinea: A preliminary study of starch granule morphotypes in Musaceae fruit
Starch granules can be well preserved in a variety of archaeological contexts, for example, in residues and sediments. Therefore, starch analysis has potential to provide another means of tracking the exploitation, dispersal and domestication of Musa bananas and Ensete. Starch granule morphotypes from fruits of Ensete glaucum and wild and cultivated Australimusa and Eumusa bananas were analyzed...
متن کاملMolecular and Cytogenetic Characterization of Wild Musa Species
The production of bananas is threatened by rapid spreading of various diseases and adverse environmental conditions. The preservation and characterization of banana diversity is essential for the purposes of crop improvement. The world's largest banana germplasm collection maintained at the Bioversity International Transit Centre (ITC) in Belgium is continuously expanded by new accessions of ed...
متن کاملDomestication, Genomics and the Future for Banana
BACKGROUND Cultivated bananas and plantains are giant herbaceous plants within the genus Musa. They are both sterile and parthenocarpic so the fruit develops without seed. The cultivated hybrids and species are mostly triploid (2n = 3x = 33; a few are diploid or tetraploid), and most have been propagated from mutants found in the wild. With a production of 100 million tons annually, banana is a...
