Diagrammatic co-phylogeny comparing phytomyxid taxonomy and phylogenetic relationship of their hosts. Phytomyxea are connected to their primary host species to highlight the degree of host switches between and within vascular plant and stramenopile hosts. Left hand side: a modified version of the tree shown in Figure 1. Dotted branches were shortened (scale indicated). Right hand side: diagrammatic tree of green plants and stramenopiles (based on [4, 28, 29]). Red?=?monocot plant host, Green?=?eudicots plant hosts; Blue?=?stramenopile host.
