Loss of DET1 in High Pigment 2 Tomato Prevents High Temperature Repression of Anthocyanin Biosynthesis in Fruit Through HY5 Stabilization

Plant, Cell &Environment, EarlyView.
ABSTRACT Global warming impacts several aspects of plant physiology, with important negative effects on crop yield and production of secondary metabolites, such as anthocyanins. The anthocyanin content of vegetables and fruits has attracted public interest in the last two decades due to its health benefits, leading to the development of novel ...

Synthesis of Prussian blue-embedded porous polymer for detection and removal of Cs ions [PDF]

, 2018
A Prussian blue (PB)​-​embedded coordination polymer (COP) was prepd. by simple incorporation of PB into a COP composed of 1,​1,​2,​2-​tetrakis(4-​carboxyphenyl)​ethane and the Zn ion during the synthesis of COP. The PB-​COP was prepd.

DET1 and HY5 Control PIF4-Mediated Thermosensory Elongation Growth through Distinct Mechanisms

Cell Reports, 2017
Summary: Plant growth and development are defined by environmental cues. The transcription factor PHYTOCHROME INTERACTING FACTOR 4 (PIF4) is the central signaling hub that integrates environmental cues, including light and temperature, to regulate growth

Time‐ and space‐resolved transcriptional regulation in Arabidopsis thaliana

Plant Biology, EarlyView.
Transcript abundance patterns in time and space of kinases, E3 ligases and transcription factors in Arabidopsis thaliana demonstrate ample room for dynamic and specific regulation of metabolism and stress responses. Abstract General metabolism and responses to internal or external signals are tightly regulated in plants.

Daytime temperature is sensed by phytochrome B in Arabidopsis through a transcriptional activator HEMERA. [PDF]

, 2019
Ambient temperature sensing by phytochrome B (PHYB) in Arabidopsis is thought to operate mainly at night. Here we show that PHYB plays an equally critical role in temperature sensing during the daytime.

COP1 Contributes to UVB-Induced Signaling in Human Keratinocytes [PDF]

Journal of Investigative Dermatology, 2010
UVB irradiation has been shown to trigger a broad range of changes in gene expression in human skin; however, factors governing these events are still not well understood. In this study, we show that human constitutive photomorphogenic protein-1 (huCOP1), an E3 ligase, contributes to the orchestration of UVB response of keratinocytes.

CUL4B-DDB1-COP1-mediated UTX downregulation promotes colorectal cancer progression

Experimental Hematology & Oncology, 2023
Background UTX (encoded by KDM6A), a histone demethylase for H3K27me2/3, is frequently mutated in human cancers. However, its functional and regulatory mechanisms in colorectal cancer (CRC) remain unclear.

Reduction in Synaptic Vesicle Protein Abundance but Increased Amounts of Nsg2 and Lpcat1 in Cerebral Cortices Without the Endosomal SNARE Proteins Vti1a and Vti1b

PROTEOMICS, Volume 26, Issue 5, Page 86-97, May 2026.
ABSTRACT Absence of the endosomal SNAREs vti1a and vti1b results in perinatal death and severe neuronal phenotypes in mice, while lack of one of these proteins results in minor phenotypes. Proteomic differences were investigated to obtain a deeper insight into processes in which vti1a and vti1b are involved.

COP1 E3 ligase protects HYL1 to retain microRNA biogenesis [PDF]

Nature Communications, 2014
Constitutive photomorphogenic 1 (COP1) is a RING-finger E3 ligase that plays a central role in photomorphogenesis by destabilizing many light-regulated transcription factors and photoreceptors. Here, we reveal a novel function for COP1 E3 ligase in controlling global miRNA biogenesis in Arabidopsis thaliana.

Photoactivated UVR8-COP1 module determines photomorphogenic UV-B signaling output in Arabidopsis. [PDF]

PLoS Genetics, 2014
In Arabidopsis, ultraviolet (UV)-B-induced photomorphogenesis is initiated by a unique photoreceptor UV resistance locus 8 (UVR8) which utilizes its tryptophan residues as internal chromophore to sense UV-B. As a result of UV-B light perception, the UVR8
