Analysis of molecular variance (AMOVA) in cloned ITS sequences
Hypotheses Percentage of variation
among groups among individuals within groups within individuals
H1 4.33NS 25.76* 69.91*
H2 24.01* 13.69* 62.30*
H3 21.39* 11.31* 67.30*

AMOVA was used to test whether variation was partitioned among groups that corresponded to: H1) the clades of the cpDNA phylogeny (i.e., P. marginata/P. latifolia clades and P. allionii clade); H2) current taxonomical classification (P. marginata, P. latifolia and P. allionii); H3) taxonomical classification with the subdivision of P. marginata in two cytotypes (P. marginata dodecaploids, P. marginata hexaploids, P. latifolia and P. allionii). * = P value < 0.01; NS = not significant.
