Fig. 3From: Brassicaceous roots as an unexpected diversity hot-spot of helotialean endophytesMorphological characterization of the isolates of this study. a Principal component analysis (PCA) ordination of isolates according to their quantitative morphological characters. Each point represents one isolate, with color indicating the species to which it belongs to. b PCA scores showing the contribution of each morphological character to the separation of the isolates, as indicated by the direction and magnitude of the arrows. c Distribution of selected quantitative characters across the isolates’ phylogeny. Colors next to tree tips indicate the isolates’ species (see color key). Note that trees for conidial volume and conidial length-to-width ratio contain only a subset of the species that produced conidia in culture. For trees showing all the characters included in b, see Fig. S3. Abbreviations: GR, growth rate on each agar medium (indicated by subscript); Pigm, degree of dematiaceous pigmentation on each agar medium (indicated by subscript)Back to article page
