The procedure of the MDS was previously described. Briefly, each molecule of a target DNA extracted from plants was labelled with a distinct DNA barcode, lineally amplified using a single primer and DNA polymerase, and subjected to NGS. Because original mutations that existed in plant DNA will be conserved among NGS reads harboring identical barcodes, they can be distinguished from erroneous mutations caused by PCR or NGS. In this work, we have prepared 4 test reactions to test 1) dual targeting in one reaction, 2) effect of pre-treatment of DNA repair enzymes, and 3) sensitivity of this method by inputting low amount of DNA with a known mutation.}, title = {Consideration of conditions for extremely deep sequencing to detect mutations in plant DNA}, year = {2022} }
