Two Swd2-like euchromatin proteins in Arabidopsis. a Neighbor-joining tree of full-length Swd2-like proteins from representative species. The plant clade can be divided into two sub-clades containing each a Swd2-Like isoform, (a) and (b). The numbers indicate bootstrap values from 1000 replicates. Scale for sequence divergence is represented by a bar. Gene and protein IDs are given in Additional file 1: Table S1. b S2La and S2Lb are euchromatic proteins. Immunodetection of GFP-tagged S2La and S2Lb proteins in interphase cotyledon nuclei (green). DNA is counterstained with DAPI (blue). Scale bar, 2 μm
