Genome size in Cyperaceae
Original language description
In organisms with monocentric chromosomes, the chromosome numbers are sufficient for the estimation of ploidy level. In Cyperaceae the detection of polyploidy is complicated by chromosomal fusion and fragmentation (symploidy and agmatoploidy) due to holokinetic nature of chromosomes. Studying karyotype and genome size in Cyperaceae, we combined (i) molecular methods, (ii) flow cytometry, and (iii) traditional chromosome counts in Carex and Eleocharis. These genera are contrasting in (i) number of species, (ii) evolutionary centres, (iii) ecological diversification, but mainly in (iv) genome size and chromosome size variation, which is in Eleocharis one of the largest known among angiosperm genera (36.5 fold: from 8.1 Mbp per chromosome in E. quinqueflora to 296 Mbp per chromosome in E. austriaca). We analysed the following genomic parameters: (i) genome size, (ii) chromosome number, (iii) chromosome size, (iv) AT/GC composition, (v-vi) Ty3-gypsy and Ty1-copia retrotransposons diversity
