Summary

Editing Factor: CP31B
Synonym: Chloroplast RNA-binding Protein 31B
Description: The cpRNP family member CP31A exhibit highly specific and diverse defects in chloroplast RNA metabolism; Analysis of cp31a and cp31a/cp31b double mutants uncovers that these 2 paralogous genes participate nonredundantly in a combinatorial fashion in processing a subset of chloroplast editing sites in vivo; A genome-wide analysis of chloroplast transcript accumulation in cp31a mutants detected a virtually complete loss of the chloroplast ndhF mRNA and lesser reductions for specific other mRNAs; Fluorescence analyses show that the activity of the NADH dehydrogenase complex, which also includes the NdhF subunit, is defective in cp31a mutants
