dc.description.abstract
Fluorescent chromosome banding and measurements of nuclear DNA content by image cytometry of Feulgen-stained cells were performed in one sample each of eight diploid (2n = 24) species of Solanum: S. endoadenium, S. argentinum, S. pseudocapsicum, S. atropurpureum, S. elaeagnifolium, S. sisymbriifolium, S. chenopodioides, and S. palustre. The species studied could be distinguished by heterochromatin amount, banding patterns, and genome size. They exhibited only GC-rich heterochromatin and showed a comparatively low heterochromatin amount (expressed as percentage of haplotype karyotype length), ranging from 2.10 in S. argentinum to 8.37 in S. chenopodioides.<br />Genome size displayed significant variation between species, with 1C-values ranging from 0.75 pg (735 Mbp) in S. palustre to 1.79 pg (1,754 Mbp) in S. sisymbriifolium. No significant correlation between genome size and heterochromatin amount was observed, but<br />intrachromosomal asymmetry index (A1) was negative and significantly correlated with heterochromatin amount. DNA content was positively and significantly correlated with<br />karyotype length. DNA C-value distribution in the genus as well as karyotype affinities and relationships between species are discussed in relation to different infrageneric classifications of Solanum.
