    Nuclear genome size and genomic distribution of ribosomal DNA in Musa and Ensete (Musaceae): taxonomic implications

  • Original language description

    Nuclear DNA content and genomic distributions of 5S and 45S rDNA were examined in nine-teen diploid accessions of the genus Musa representing its four sections Eumusa, Rhodochla-mys, Callimusa and Australimusa, and in Ensete gilletii, which was outgroupin this study. In the Eumusa (x = 11), 2C DNA content ranged from 1.130 to 1.377 pg, M. bal-bisiana having the lowest DNA content of all sections. M. beccarii (x = 9), a representative of Callimusa, had the highest 2C nuclear DNA content (1.561 pg). Species belonging to Rhodo-chlamys (x = 11) and Australimusa (x = 10) had 2C DNA contents ranging from 1.191 to 1.299 pg and from 1.435 to 1.547 pg, respectively. E. gilletii (x = 9) had 2C DNA content of 1.210 pg. The number of 5S rDNA loci in Musa varied from 4 to 8 per diploid cell. While different numbers of 5S loci were observed within Eumusa and Rhodochlamys, four 5S loci were observed in all accession of Australimusa. M. beccarii (Callimusa) and E. gilletii con-tained 5S rRNA gene...

    Velikost jaderného genomu a genomická distribuce ribozomální DNA rodu Musa a Ensete (Musaceae)

  • Czech description

    U devatenácti diploidních položek rodu Musa, zahrnující čtyři sekce - Eumusa, Rhodochla-mys, Callimusa a Australimusa, a u Ensete gilletii, byl zjišťován obsah jaderné DNA a geno-mická distribuce 5S a 45S rDNA. V sekci Eumusa (x = 11) se obsah jaderné DNA pohyboval od 1.130 do 1.377 pg, M. balbisiana měla ze všech sekcí nejnižší obsah jaderné DNA. M. beccarii (x = 9), reprezentující sekci Callimusa, měla nejvyšší obsah jaderné DNA (1.561 pg). Druhy, patřící do Rhodochlamys (x = 11) a Australimusa (x = 10) měly obsah jaderné DNA od 1.191 do 1.299 pg, respektive od 1.435 do 1.547 pg. E. gilletii (x = 9) měla obsah jaderné DNA od 1.210 pg. Počet signálů 5S rDNA se u diploidů pohyboval od 4 do 8. Eumusa a Rhodochlamys měly počet signálů různý, u Australimusy byly signály vždy čtyři. M. beccarii (Callimusa) a E. gilletii měla shluky 5S rRNA na pěti, respektive šesti chromozómech. Počet signálů odpovídajících 45S rDNA byl stálý v jednotlivých sekcích. Analýza velikosti genomu, počet chrom...
