Karyotype Analysis of Paronychia anatolica subsp. anatolica (Caryophyllaceae, Paronychioideae)

Abstract

In the study, the chromosomal data of Paronychia anatolica subsp. anatolica are provided for the first time. The diploid chromosome number and karyotype formula are 2n = 2x = 18 = 16m + 2sm with metacentric chromosomes out of submetacentric chromosome 1. No all chromosomes have satellite and secondary constriction. The values of total haploid length and mean chromosome length are very low with 14.47 and 1.61 μm, respectively; because the taxon has low numbers and relatively small of chromosomes, which are range from 1.21 to 1.84 μm. The karyotype is symmetrical type. Within the scope of all the results, the data will provide important contributions to the cytotaxonomy of genus Paronychia. Especially, taxon contains very different karyotypic data from other subspecies and it is very important knowledge for cytotaxonomic point of view.
