Plant cell elongation is controlled by endogenous hormones, including brassinosteroid (BR) and gibberellin (GA), and by environmental factors, such as light/darkness. The molecular mechanisms underlying the convergence of these signals that govern cell growth remain largely unknown. We previously showed that the chromatin-remodeling factor PICKLE/ENHANCED PHOTOMORPHOGENIC1 (PKL/EPP1) represses ...

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...

The chromatin modifying Polycomb group (PcG) and trithorax group (trxG) proteins are central regulators of cell identity that maintain a tightly controlled balance between cell proliferation and cell differentiation. The opposing activities of PcG and trxG proteins ensure the correct expression of specific transcriptional programs at defined developmental stages. Here, we report that the chroma...

Dynamic regulation of chromatin structure is of fundamental importance for modulating genomic activities in higher eukaryotes. The opposing activities of Polycomb group (PcG) and trithorax group (trxG) proteins are part of a chromatin-based cellular memory system ensuring the correct expression of specific transcriptional programs at defined developmental stages. The default silencing activity ...

The small GTPases of the Rho family are intimately involved in integrin-mediated changes in the actin cytoskeleton that accompany cell spreading and motility. The exact means by which the Rho family members elicit these changes is unclear. Here, we demonstrate that the interaction of paxillin via its LD4 motif with the putative ARF-GAP paxillin kinase linker (PKL) (Turner et al., 1999), is crit...

Photomorphogenesis is a critical plant developmental process that involves light-mediated transcriptome changes, histone modifications, and inhibition of hypocotyl growth. However, the chromatin-based regulatory mechanism underlying this process remains largely unknown. Here, we identify ENHANCED PHOTOMORPHOGENIC1 (EPP1), previously known as PICKLE (PKL), an ATP-dependent chromatin remodeling f...

The L-II element (-149 to -126 bp) in the enhancer unit of the rat pyruvate kinase L (PKL) gene is required for cell-type-specific transcription and induction by carbohydrates. This element was found to bind multiple nuclear proteins with different heat stabilities. A heat-labile factor was shown to be hepatocyte nuclear factor (HNF) 4 by the electrophoretic mobility-shift assay (EMSA) using va...

The purpose of this study is to determine the existence Mataram City Regional Regulation No. 10/2015 concerning Street Vendors (PKL) in increasing potential for regional taxes and fees on PKL sector government city impact after Sector was designated as a Potential Tax Retribution Government City. research method used Normative Law method. While technique collecting legal materials use library r...

Active nuclear import of protein is controlled by nuclear localization signals (NLSs), but nuclear export is not understood well. Nuclear trafficking of the catalytic (C) subunit of cAMP-dependent protein kinase (cAPK) is critical for regulation of gene expression. The heat-stable inhibitor (PKl) of cAPK contains a nuclear export signal (NES) that triggers rapid, active net extrusion of the C-P...
