From: Evolution of plant RNA polymerase IV/V genes: evidence of subneofunctionalization of duplicated NRPD2/NRPE2-like paralogs in Viola (Violaceae)

Figure 1

Sequence characteristics of NRPD2/E2. A. The corresponding localization in Arabidopsis NRPD2/E2 of the region amplified for Violaceae. B. Specifications for the region in Violaceae. Filled triangles denote PCR primers used to amplify the two standard PCR regions, and open triangles denote primers used to amplify shorter stretches if PCRs with the standard primers repeatedly failed. NRPD2/E2 domains involved in recognition and binding to other Pol IV/V subunits are indicated, based on findings in yeast Pol II [2].
