Distribution of antisense PACs in M. truncatula and Arabidopsis

Case 1	M. truncatula				Arabidopsis

¹Cases 1–4 are as described in Wu et al. [7]. Specifically:

Case 1 – antisense PACs map to the 3′-UTR of an adjacent, convergently-transcribed gene.

Case 2 – antisense PACs map to the CDS or 5′-UTR of an adjacent, convergently-transcribed gene.

Case 3 – antisense PACs are near the end of an adjacent, convergently-transcribed gene, but do not map to the nearby annotated gene.

Case 4 – antisense PACs cannot be attributed to an adjacent, convergently-transcribed gene.
