Correction

Saleh, A., Alvarez-Venegas, R., Yilmaz, M., Le, O., Hou, G., Sadder, M., Al-Abdallat, A., Xia, Y., Lu, G., Ladunga, I., and Avramova, Z. (2015). The highly similar Arabidopsis homologs of trithorax ATX1 and ATX2 encode proteins with divergent biochemical functions. Plant Cell 20: 568–579.

Figure 7C (WRKY70 ChIP-PCR assay) has been corrected to clarify that the wild-type control sample for H3K4m3 was run on a separate gel from the atx1 and atx2 samples, indicated by the space (white line, bottom row). The samples for H3K4m2 (top row) were run together on the same gel. The legend and labeling on the figure have been amended slightly for clarity. The original conclusions of the manuscript are unaltered by these corrections.

Original: Expression and H3K4 Methylation Patterns of WRKY70 in Wild-Type, atx1, and atx2 Chromatin.

(C) WRKY70 amplified from ChIP assays of wild-type, atx1, and atx2 flower chromatin immunoprecipitated with antibodies distinguishing between di- and trimethylated H3K4 isoforms. Labeling is as in Figure 5C. A schematic illustration of the WRKY70 gene including the regions amplified for the ChIP assay is shown at top of the panel.

(C) WRKY70 amplified from ChIP assays of wild-type, atx1, and atx2 flower chromatin immunoprecipitated with antibodies distinguishing between di- and trimethylated H3K4 isoforms. The control wild-type samples for H3K4m3, separated by a space (white line in the bottom panel), were resolved in a different gel from atx1 and atx2 samples. The blots were developed and processed in parallel. I, input sample representing 10% of the template amount used for the immunoprecipitation. −Αb and +Ab are immunoprecipitated chromatins without and with added antibody, respectively. A schematic illustration of the WRKY70 gene including the regions amplified for the ChIP assay is shown at top of the panel.
