Fig. 2From: Genome-wide characterization of intergenic polyadenylation sites redefines gene spaces in Arabidopsis thaliana Schema of different classes of IPACs. SE-IPAC, IPAC in the 3’-UTR extension of its 5’ sense gene (Sense-Extension); A-IPAC, IPAC that is located in another antisense gene (Antisense); SO-IPAC, IPAC that is far from all nearby genes (Sense-Orphan)Back to article page
