The Role of Canonical and Noncanonical Pre-mRNA Splicing in Plant Stress Responses

Figure 2

The types of noncanonical pre-mRNA splicing and splicing-like events in plants. (a) variations affecting multiple exons; (b) intra-exonic deletion; (c) generation of chimeric mRNAs; (d) frameshifting as a result of intron excision. Exons are represented by grey, dark grey and black boxes, and introns-by horizontal solid lines between the boxes. Dashed lines above and below the exons and introns depict excision events. The dashed box in part (d) outlines a frameshift caused by an intron excision (details can be found in the Section 3.2). In this case, the spliced mRNA produces a protein with a different amino acid sequence at the C-terminus.
