The N-terminal extension is crucial for DXO1 function in chloroplast-related processes. (A) Two-week-old dxo1-2 transgenic plants. (B) RT-qPCR of selected mRNAs in dxo1-2 and dxo1-2 expressing DXO1 variants. Gene identifiers are indicated below the graph. Results are the mean of three independent biological replicates with error bars representing standard deviation; *P ≤ 0.05; **P ≤ 0.01; ***P ≤ 0.001 (t-test). (C) Small RNA detection by northern blotting; siRNA accumulation from sRNA-seq (log2FC) is indicated; 5S rRNA, loading control. (D) Activity toward NAD+-capped RNA substrate in the presence of PAP. Reaction products after 30 min incubation were resolved by 8% urea-PAGE. See Supplementary Figure S6 for additional information.
