CEACAM7 and infection: To test whether the observed differences of oval and falcate conidia regarding MRE sensing and germination patterns in soil might affect the ability of the spore types to infect roots, a C. graminicola wild‐type strain expressing a tdTomato‐labelled histone marker, CgM2::RH2B (Nordzieke, Sanken, et al. 2019), was used for root infection experiments.
