The CKH2/PKL chromatin remodeling factor negatively regulates cytokinin responses in Arabidopsis calli.
Cytokinins promote cell division and chloroplast development in tissue culture. We previously isolated two mutants of Arabidopsis thaliana, ckh1 (cytokinin-hypersensitive 1) and ckh2, which produce rapidly growing green calli in response to lower levels of cytokinins than those found in the wild type. Here we report that the product of the CKH2 gene is PICKLE, a protein resembling the CHD3 clas...
متن کاملPICKLE chromatin-remodeling factor controls thermosensory hypocotyl growth of Arabidopsis.
Temperature is a major signal that governs plant distribution and shapes plant growth. High ambient temperature promotes plant thermomorphogenesis without significant induction of heat-stress responses. Although much progress of warm temperature-mediated plant growth has been made during recent years, the thermomorphogenic signalling pathway is not well understood. We previously revealed that P...
متن کاملBap170, a subunit of the Drosophila PBAP chromatin remodeling complex, negatively regulates the EGFR signaling.
BAP and PBAP constitute the two different forms of the Drosophila melanogaster Brahma chromatin remodelers. A common multisubunit core, containing the Brahma ATPase, can associate either with Osa to form the BAP complex or with Bap170, Bap180, and Sayp to constitute the PBAP complex. Although required for many biological processes, recent genetic analyses revealed that one role of the BAP compl...
متن کاملPICKLE is a CHD3 chromatin-remodeling factor that regulates the transition from embryonic to vegetative development in Arabidopsis.
The life cycle of angiosperms is punctuated by a dormant phase that separates embryonic and postembryonic development of the sporophyte. In the pickle (pkl) mutant of Arabidopsis, embryonic traits are expressed after germination. The penetrance of the pkl phenotype is strongly enhanced by inhibitors of gibberellin biosynthesis. Map-based cloning of the PKL locus revealed that it encodes a CHD3 ...
متن کاملChromatin associated SETD3 negatively regulates VEGF expression
SETD3 is a member of the protein lysine methyltransferase (PKMT) family, which catalyzes the addition of methyl group to lysine residues. Accumulating data suggest that PKMTs are involved in the regulation of a broad spectrum of biological processes by targeting histone and non-histone proteins. Using a proteomic approach, we have identified 172 new SETD3 interacting proteins. We show that SETD...
