Identification of csR-trnA-1 and csR-trnA-2. (A) An diagram showing the location of csR-trnA-1 and csR-trnA-2 in chloroplast tRNA-Ala. Two exons of tRNA-A are indicated by boxes. (B) and (C) Size distribution of the csR-trnA-1 family and the csR-trnA-2 family in sequence datasets with core sequences (underlined in Additional File 10). (D) and (E) Northern blotting of csR-trnA-1 and csR-trnA-2 in the HT seedlings of Chinese cabbage. U6 spliceosomal RNA was used as an RNA loading control.
