Fig 3. Summary of rDNA site number variation in Meehania urticifolia and Glechoma.
Loss of 35S rDNA sites inferred from a doubling of the Meehania pattern and seen in G. grandis, G. hederacea, G. longituba (i) is indicated by stars. 1: Loss of 35S rDNA from chromosomes carrying 5S rDNA. 2: Loss of 35S rDNA from chromosomes without 5S rDNA. Roman numerals (i–v) indicate the five distribution types of rDNA (see Results). Number of individuals studied in brackets. Scale bar = 5 μm.
