About the cover: Chromatin remodeling complexes play essential roles in plant development. In this issue, Dong et al. (pp. 928–937) show that the SLIDE domain of the ISWI is responsible for interacting with DDT-domain proteins. In Arabidopsis, at least 12 proteins carry a DDT domain, suggesting ISWI may achieve multiple functions via formation of different chromatin remodeling complexes with different DDT-domain proteins.
