Eranthis stellata

Notes.

In all five studied populations of E. stellata from Primorsky Krai of Russia and Jilin Province of China, the somatic and basic chromosome numbers are 2 n = 16 and x = 8, respectively (Table 1; Fig. 2B-C). Five pairs of chromosomes (I-V) are metacentric, two pairs (VI-VII) are submetacentric, and one pair (VIII) is acrocentric (Tables 2 and 3; Fig. 3). A pair of submetacentric chromosomes (VII) exhibits a secondary constriction. The karyotype formula of E. stellata is 2 n = 2 x = 16 = 10m + 2sm + 2smsat + 2t. No B was observed in this species. Here, we present the results of the karyomorphological analysis of E. stellata from the "Academicheskaya Station" population (pop. 2).

Notes: THL - total haploid length, CVCL - Coefficient of Variation of Chromosome Length, MCA - Mean Centromeric Asymmetry, CVCI - Coefficient of Variation of Centromeric Index; mean value (standard deviation). m - metacentric chromosome; sm - submetacentric chromosome; st - subtelocentric chromosome; t - acrocentric chromosome; sat - satellite chromosome; B - B chromosome.
