Isolated clones were characterized in terms of copy number, genomic distribution in M. acuminata and M. balbisiana, and sequence similarity to known DNA sequences. Ribosomal RNA genes have been the most abundant sequences recovered. FISH with probes for DNA clones Radkal and Radkal, which carry different fragments of Musa 26S rDNA, and Radkal, for which no homology with known DNA sequences has been found, resulted in clear signals at secondary constrictions. Only one clone carrying 5S rDNA, named Radkal, has been recovered. All remaining DNA clones exhibited more or less pronounced clustering at centromeric regions. The study revealed small differences in genomic distribution of repetitive DNA sequences between M. acuminata and M. balbisiana, the only exception being the 5S rDNA where the two Musa clones under study differed in the number of sites.
