Identification of the three qpe9–1 mutants generated using CRISPR/Cas9. a Two specific target guide RNA sequences located in the second and fifth exons were selected to edit qPE9–1. Target guide sequences are marked in pink. b The mutation sites of qPE9–1 in the three mutants, qpe9–1#1, qpe9–1#2, and qpe9–1#3, were confirmed by sequencing. Base variation is shown by the red box
