CWM2 - Plant Editosome Database - BIG Data Center

Summary

Editing Factor: CWM2
Synonym: RRD2
Description: In addition to mutations in CELLULOSE SYNTHASE1 (CESA1) and CESA3, a forward genetic screen identified two independent defective genes encoding pentatricopeptide repeat (PPR)-like proteins (CELL WALL MAINTAINER1 [CWM1] and CWM2) as conferring tolerance to C17; Functional analysis revealed that mutations in these PPR proteins resulted in defective cytochrome c maturation and activation of mitochondrial retrograde signaling, as evidenced by the induction of an alternative oxidase; These mitochondrial perturbations increased tolerance to cell wall damage induced by cellulose deficiency; The C17 tolerance of cwm2 was partially lost upon depletion of the mitochondrial retrograde regulator ANAC017, demonstrating that ANAC017 links mitochondrial dysfunction with the cell wall
