摘　　要：RNA editing is a post-transcriptional process that alters the genetic information of mRNAs,so that the translated proteins deviate from those predicted by the genomic DNA templates.RNA editing occurs in a wide range of eukaryotes,including protists,multicellular animals,and land plants(Gray,2012;Ichinose and Sugita,2016).RNA editing in animals,dominated by A-to-I synonymous editing with low editing efficiency(20e30%),might play important roles in the regulation of gene expression(Wang et al.,2013).In contrast,RNA editing in plant organelles is usually nonsynonymous,affecting mostly the 2nd and 1st codon positions with very high editing efficiency(~80%).In plants,RNA editing is thought to affect plant phenotype and growth by restoring evolutionarily conserved amino acids and ensuring the correct folding of trans-membrane proteins on the respiratory chain complex(Sloan,2017).
