Light signaling plays an essential role in controlling higher plants' early developmental process termed as photomorphogenesis. Transcriptional regulation is a vital mechanism that orchestrated by transcription factors and other regulatory proteins working concert to finely tune gene expression. Although many factors/regulators have been characterized the light-signaling pathway, their interregulation remains largely unknown. Here, we show PHYTOCHROME-INTERACTING FACTOR3 (PIF3) PIF1 directly...
Abstract 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 remains largely unknown. Here, we identify ENHANCED PHOTOMORPHOGENIC1 (EPP1), previously known as PICKLE (PKL), an ATP-dependent chromatin remodeling factor chromodomain/helicase/DNA binding family, repressor photomorphogenesis in Arabidopsis...
Chloroplasts are the site of numerous biochemical reactions including photosynthesis, but they also produce reactive oxygen species (ROS) that negatively affect chloroplast integrity. The chaperone-like CDC48 complex plays critical roles in ubiquitin-dependent protein degradation yeast and mammals, its function plants is largely unknown. Here, we show defects CDC48A cofactors UFD1 NPL4 lead to accumulation ubiquitinated proteins Arabidopsis thaliana. We reveal two plastid genome-encoded...
Summary Arabidopsis gain‐of‐resistance mutants, which show HR‐like lesion formation and SAR‐like constitutive defense responses, were used well as tools to unravel the plant mechanisms. We have identified a novel mutant, designated expresser of PR genes 30 ( cpr30 ), that exhibited dwarf morphology, resistance bacterial pathogen Pseudomonas syringae dramatic induction defense‐response gene expression. The ‐conferred growth defect morphology responses are dependent on ENHANCED DISEASE...
Summary Full‐length cDNAs are very important for genome annotation and functional analysis of genes. The number full‐length from maize ( Zea mays L.) remains limited. Here we report the construction a enriched cDNA library osmotically stressed seedlings by using modified CAP trapper method. From this library, 2073 (accession numbers DQ244142 – DQ246214 ) were collected further analyzed sequencing both 5′‐ 3′‐ends. A total 1728 (83.4%) sequences did not match known mRNA in GenBank database...
Abstract Light and temperature are 2 major environmental factors that affect the growth development of plants during their life cycle. Plants have evolved complex mechanisms to adapt varying external environments. Here, we show JASMONATE ZIM-domain protein 3 (JAZ3), a jasmonic acid signaling component, acts as factor integrate light in regulating seedling morphogenesis. JAZ3 overexpression transgenic lines display short hypocotyls under red, far-red, blue warm (28 °C) conditions compared...
Abstract Light is a key environmental signal that regulates plant growth and development. While posttranscriptional regulatory mechanisms of gene expression include alternative splicing (AS) pre-messenger RNA (mRNA) in both plants animals, how light signaling affects AS largely unknown. Here, we identify DExD/H helicase U2AF65-associated protein (UAP56) as negative regulator photomorphogenesis Arabidopsis thaliana. UAP56 encoded by the homologs UAP56a UAP56b. Knockdown led to enhanced...
Small ubiquitin-like modifier (SUMO) post-translational modification (SUMOylation) plays essential roles in regulating various biological processes; however, its function and regulation the plant light signaling pathway are largely unknown. SEUSS (SEU) is a transcriptional co-regulator that integrates temperature pathways, thereby growth development Arabidopsis thaliana. Here, we show SEU substrate of SUMO1, substitution four conserved lysine residues disrupts SUMOylation SEU, impairs photo-...
Plants have evolved light signaling mechanisms to optimally adapt developmental patterns the ambient environments. CONSTITUTIVE PHOTOMORPHOGENIC1 (COP1) and LONG HYPOCOTYL5 (HY5) are two critical components in pathway Arabidopsis thaliana . COP1 acts as an E3 ubiquitin ligase that targets positive regulators, such HY5, leading their degradation darkness. However, functional analysis of COP1‐HY5 module maize ( Zea mays ) has not been reported. Here, we investigated expression roles HY5...
