Summary

Editing Factor: CWM1
Synonym: CELL WALL MAINTAINER 1
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; CWM1 also edits sites ccmCeU463RC, ccmBeU428SL, and nad5eU609VV; Surprisingly, the P. patens editing factor edited all target sites when expressed in the Arabidopsis cwm1 mutant background, even when carboxy-terminally truncated; Conversely, neither Arabidopsis CWM1 nor CWM1-PPR79 chimeras restored editing in P. patens ppr79 knockout plants
