Gene ID Name Evidence / Role Function (this paper)
MpRBOHA missing experimental subject One of only two M. polymorpha respiratory burst oxidase homologs; the MprbohA MprbohB double null forms a disorganized cell mass, showing RBOH-derived ROS positively regulate growth/cell proliferation and are essential for morphogenesis.
MpRBOHB missing experimental subject The second M. polymorpha RBOH; complete null and double-mutant analyses show MpRBOHA/MpRBOHB-derived ROS are indispensable for development and cuticle/cell-wall morphogenesis.
Mp8g08780 MpYUC2 experimental tool Apical-meristem marker; a tdTomato-NLS reporter driven by the MpYUC2 promoter was used to assess meristem organization.
