FIGURE 1.

Gene structure of AT2G21280 and a diagram of T-DNA and sgRNA mutants. White boxes represent the 5′- and 3′-untranslated regions, black boxes represent exons, and black lines represent introns. Triangles and arrowheads in them mark the locations of T-DNA insertion of the SALK lines and indicate the directions of the T-DNA, respectively. Perpendicular arrows mark the targeting sites of sgRNAs. Positions of primers used for T-DNA insertion mutants identification in Supplementary Figure 1 and the RT-PCR analysis in Supplementary Figure 2 are marked with arrows.
