Abstract :
White blister rust causal agents, previously
assigned to the genus Albugo, are obligate plant
pathogens affecting numerous plant families. The
genus Wilsoniana has been erected from the genus
Albugo to accommodate species infecting hosts in the
Caryophyllales. Starting from spring 2018, we
observed symptoms resembling white blister rust
disease on leaves of Amaranthus retroflexus L. in the
northern Iran. The specimens were subjected to
molecular study by analyzing cox2, LSU and ITS
rDNA sequences and morphological data sets. The
results confirmed that the specimens belong to
Wilsoniana amaranthi (Schwein.) Y.J. Choi, Thines
& H.D. Shin (Albuginales, Oomycota). To our
knowledge, this is the first confirmed and
documented record of W. amaranthi (ex Amaranthus
retroflexus) from both Iran and West Asia. The
results of this study will provide a reference for
further resolution of W. amaranthi species concept.
