We also established curtain heterogeneity by average nucleus area and relative content of the DNA. Polisomatia was shown in root meristem tissue. The chromosome numbers form range from 10 to 68 chromosomes, at the same time aneuploid cells are dominant. Using PCR and sequencing we analysed the inner transcribed spacer (ITS) structure of ribosomal DNA of investigated D.antarctica plants of fifteen maritime Antarctica populations. We established that the length of D. antarctica ITS amounts 669 b.p. Nucleotide sequence of ITS of different populations plants is characterized by high similarity - 99,9%.5635 Product Description popup.authors popup.nrat_date 2020-04-02 Close
