Analysis of molecular variance for Cronartium ribicola populations sampled across geographic regions, hosts and landscapes in North America.

aComparison among and within groups of populations arranged by geographic origin, type of stand, pine host and elevation.bProbability that the observed value is larger than the value calculated following permutation (**pct values were tested by permuting whole populations among groups.cSee S1 Table for details. Three pine species in western populations were considered: P. monticola, P. albicaulis, and P. flexilis. Other pine species (P. strobus, P. strobiformis) would have generated confounded effect of host and geography.Analysis of molecular variance for Cronartium ribicola populations sampled across geographic regions, hosts and landscapes in North America.
