Figure 9From: Dynamic distribution patterns of ribosomal DNA and chromosomal evolution in Paphiopedilum, a lady's slipper orchidThe relationship between polymorphism of 5S-NTS sequences and numbers of observed 5S rDNA signals. Line indicates trend derived from linear regression analysis based on 5S-NTS within-species polymorphic sites and minimum numbers of visible 5S signals (data from Table 1.). P < 0.01, R^2 = 0.21.Back to article page
