Abstract
The blast fungus Magnaporthe oryzae (syn. Pyricularia oryzae) is a destructive plant pathogen that can infect about 50 species of both wild and cultivated grasses, including important crops such as rice and wheat. M. oryzae is composed of genetically differentiated lineages that tend to infect specific host genera. To date, most studies of M. oryzae effectors have focused on the rice-infecting lineage. We describe a clone resource of 195 effectors of Magnaporthe species predicted from all the major host-specific lineages. These clones are freely available as Golden Gate-compatible entry plasmids. Our aim is to provide the community with an open source effector clone library to be used in a variety of functional studies. We hope that this resource will encourage studies of M. oryzae effectors on diverse host species.
Highlights
Pyricularia oryzae) is an important plant pathogen that is able to infect around 50 species of both wild and cultivated grasses, including important cereals of the Poaceae family
The global population of M. oryzae is composed of genetically differentiated lineages that, in some cases, still exhibit a measurable degree of gene flow (Gladieux et al 2018; Langner et al 2018)
Fungal isolates from each of those lineages show a preference for a specific host and encode distinct repertoires of effector genes (Yoshida et al 2016)
