Karyotypes of two endemic species of Asterothamnus Novopokr. (Asteraceae) from South Siberia (Tuva)
Abstract
The karyotypes of two endemic species such as Asterothamnus heteropappoides and A. poliifolius from South Siberia were studied. Both species were diploids with the chromosome numbers of 2n = 2x = 18. The polyploidy and satellites were not found. For the first time, the chromosome morphology has been studied and the idiograms have been plotted. The chromosome sizes ranged from 6.42 to 4.23 µm for A. heteropappoides and the karyotype formula of 8m + 1sm and that from 5.88 µm to 3.64 µm for A. poliifolius and featuring the karyotype formula of 9m.Downloads
