We developed a multiplex single-base extension single-nucleotide polymorphism-typing procedure for screening large numbers of plants for mutations in mitochondrial RNA editing. The high sensitivity of the approach detects changes in the RNA editing status generated in total cellular cDNA from pooled RNA preparations of up to 50 green plants. The method has been employed to tag several nuclear encoded genes required for RNA editing at specific sites in mitochondria of Arabidopsis thaliana. This approach will allow large-scale screening for mutations in genes encoding trans-factors for many types of RNA editing as well as for other RNA modifications.
