Infection mechanisms of Rhizoctonia cerealis in wheat
iMeta, EarlyView.We discover that R. cerealis (Rc) is a primary pathogen causing sharp eyespot of wheat after 335 distinct isolates were isolated from 1683 SE‐diseased wheat plants across China over 7 years using a single hyphal tip isolation method. We then generated high‐quality reference genomes via de novo sequencing of five representative Rc isolates and ...
