The Role of Canonical and Noncanonical Pre-mRNA Splicing in Plant Stress Responses
Figure 3
Hypothetical mechanisms of noncanonical pre-mRNA splicing-like events. (a) noncanonical alternative splicing; (b) transcriptional slippage; (c) polymerase read through. Exons are represented by grey or dark grey boxes, and introns—by horizontal solid lines between the boxes. Dashed lines above and below the exons and introns depict AS events. Dashed arrows above the exons and introns depict the direction of RNA polymerase movement. IGR—intergenic region.
