A Point Mutation in the Pentatricopeptide repeat Motif of the AtECB2 Protein Causes Delayed Chloroplast Development

AtECB2 encodes a pentatricopeptide repeat（PPR） protein that regulates the editing of the plastid genes accD and ndhF.The ecb2-1 knockout shows an albino phenotype and is seedling lethal.In this study, we isolated an allelic mutant of the AtECB2 gene,ecb2-2,which showed delayed greening phenotype but...
