Fig. 3From: Grapevine bacterial communities display compartment-specific dynamics over space and time within the Central Valley of CaliforniaFaith’s phylogenetic diversity index was impacted by multiple factors of the experimental design. A Plant compartment showed the largest effect on diversity and B Root samples showed a rootstock by scion genotype effect on diversity. Boxplot hinges represent the 1st and 3rd quartiles with whiskers that represent 1.5 times the inter-quartile range; letters above box plots denote significant differences in means (TukeyHSD test)Back to article page
