Figure 4.

Networks of cis- and trans-NAT pairs formed by transcripts encoding UDP-glucosyl transferase family proteins in A. thaliana. Green ellipses represent UDP-glucosyl transferase transcripts involved in trans-NAT pairs only; red ellipses represent UDP-glucosyl transferase transcripts involved in cis-NAT pairs only; yellow ellipses represent UDP-glucosyl transferase trasncripts involved in both cis- and trans-NAT pairs. Transcripts from other protein families are shown as blue ellipses. Directed lines present the pairing relationship of two transcripts, with arrows pointing to UDP-glucosyl transferase transcripts.
