Revised Taxonomy and Expanded Biodiversity of the Phytomyxea (Rhizaria, Endomyxa) [PDF]

Journal of Eukaryotic Microbiology, Volume 67, Issue 6, Page 648-659, November/December 2020., 2020
Abstract Phytomyxea (phytomyxids) is a group of obligate biotrophic pathogens belonging to the Rhizaria. Some phytomyxids are well studied and include known plant pathogens such as Plasmodiophora brassicae, the causal agent of clubroot disease. Despite this economic importance, the taxonomy and biodiversity of this group are largely cryptic, with many ...
