Regulation of arabidopsis flowering by the histone mark readers MRG1/2 via interaction with CONSTANS to modulate FT expression.

PLoS Genet

September 2014

State Key Laboratory of Genetic Engineering, Collaborative Innovation Center for Genetics and Development, Institute of Plant Biology, School of Life Sciences, Fudan University, Shanghai, China.

Day-length is important for regulating the transition to reproductive development (flowering) in plants. In the model plant Arabidopsis thaliana, the transcription factor CONSTANS (CO) promotes expression of the florigen FLOWERING LOCUS T (FT), constituting a key flowering pathway under long-day photoperiods. Recent studies have revealed that FT expression is regulated by changes of histone modification marks of the FT chromatin, but the epigenetic regulators that directly interact with the CO protein have not been identified.

State Key Laboratory of Freshwater Ecology and Biotechnology, Institute of Hydrobiology, Chinese Academy of Sciences, Wuhan, Hubei 430072, China. Electronic address:

Peptidoglycan recognition proteins (PGRPs), which are evolutionarily conserved pattern recognition receptors from insects to mammals, recognize bacterial PGN and function in antibacterial innate immunity. The existence of alternative splicing is a common feature for PGRP family. Here the splicing pattern from the splicing at the 5' end of PGRP6 gene was identified in a teleost fish, the grass carp (Ctenopharyngodon idella).

Identification of conserved and novel microRNAs in the Pacific oyster Crassostrea gigas by deep sequencing.

PLoS One

October 2015

National & Local Joint Engineering Laboratory of Ecological Mariculture, Institute of Oceanology, Chinese Academy of Sciences, Qingdao, China.

MicroRNAs (miRNAs) play important roles in regulatory processes in various organisms. To date many studies have been performed in the investigation of miRNAs of numerous bilaterians, but limited numbers of miRNAs have been identified in the few species belonging to the clade Lophotrochozoa. In the current study, deep sequencing was conducted to identify the miRNAs of Crassostrea gigas (Lophotrochozoa) at a genomic scale, using 21 libraries that included different developmental stages and adult organs.

A genome-wide search for quantitative trait loci affecting the cortical surface area and thickness of Heschl's gyrus.

Genes Brain Behav

September 2014

Institute of Psychology, Chinese Academy of Sciences, Beijing, China; Max Planck Institute for Psycholinguistics; Donders Institute for Brain, Cognition and Behaviour, Radboud University Nijmegen, Nijmegen, The Netherlands; Graduate University of Chinese Academy of Sciences, Beijing, China.

Heschl's gyrus (HG) is a core region of the auditory cortex whose morphology is highly variable across individuals. This variability has been linked to sound perception ability in both speech and music domains. Previous studies show that variations in morphological features of HG, such as cortical surface area and thickness, are heritable.

Achieving solar overall water splitting with hybrid photosystems of photosystem II and artificial photocatalysts.

Nat Commun

Solar overall water splitting is a promising sustainable approach for solar-to-chemical energy conversion, which harnesses solar irradiation to oxidize water to oxygen and reduce the protons to hydrogen. The water oxidation step is vital but difficult to achieve through inorganic photocatalysis. However, nature offers an efficient light-driven water-oxidizing enzyme, photosystem II (PSII).

Saurogobio gracilicaudatus, originally described from the middle Yangtze River (Chang-Jiang in Chinese) basin at Yichang and Guanghua (now Laohekou), Hubei Province, South China, is here re-described, with particular concern for oromandibular structures in the mouth. It is uniquely distinguishable from all other species of Saurogobio in having a rostral cap with a slightly crenulated median portion, lips covered with brush-like, conical papillae, and a lower lip with a small, smooth and protruded central pad anteriorly free and posteriorly confluent with lateral lobes. The generic classification of this species is also discussed on the basis of oromandibular structures, which are of taxonomic importance in generic classification of gudgeons.

Guangdong Key Laboratory of Agricultural Environment Pollution Integrated Control, Guangdong Institute of Eco-Environmental and Soil Sciences, Guangzhou 510650, PR China. Electronic address:

The reduction of nitroaromatic compounds (listed as a priority pollutant) in natural subsurface environments typically coexists with dissimilatory reduction of iron oxides effected by dissolved organic matter (DOM). Investigating the impact of the DOM that influences those reduction processes is crucial for understanding and predicting the geochemical fate of these environmental species. This study investigated the impact of different molecular weight DOM fractions (DMWDs) on the 2-nitrophenol (2-NP) reduction by S.

Mo-modified Pd/Al₂O₃ catalysts for benzene catalytic combustion.

J Environ Sci (China)

July 2014

Chengdu Institute of Organic Chemistry, Chinese Academy of Sciences, Chengdu 610041, China. Electronic address:

Mo-modified Pd/Al₂O₃ catalysts were prepared by an impregnation method and tested for the catalytic combustion of benzene. The catalysts were characterized by N₂ isothermal adsorption, X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), temperature-programmed desorption of NH₃ (NH₃-TPD), H₂ temperature-programmed reduction (H₂-TPR), and high-angle annular dark-field scanning transmission electron microscopy (HAADF-STEM). The results showed that the addition of Mo effectively improved the activity and stability of the Pd/Al₂O₃ catalyst by increasing the dispersion of Pd active components, changing the partial oxidation state of palladium and increasing the oxygen species concentration on the surface of catalyst.

Based on various GPCR identification methods and classification systems, several evolutionary presumptions of different GPCR families have been reported. However, the prototype of GPCR still limits our knowledge.

Universal quantum logic gates are important elements for a quantum computer. In contrast to previous constructions on one degree of freedom (DOF) of quantum systems, we investigate the possibility of parallel quantum computations dependent on two DOFs of photon systems. We construct deterministic hyper-controlled-not (hyper-CNOT) gates operating on the spatial-mode and the polarization DOFs of two-photon or one-photon systems by exploring the giant optical circular birefringence induced by quantum-dot spins in one-sided optical microcavities.

Understanding the microscopic elementary process of chemical reactions, especially in condensed phase, is highly desirable for improvement of efficiencies in industrial chemical processes. Here we show an approach to gaining new insights into elementary reactions in condensed phase by combining quantum chemical calculations with a single-molecule analysis. Elementary chemical reactions in liquid-phase, revealed from quantum chemical calculations, are studied by tracking the fluorescence of single dye molecules undergoing a reversible redox process.

It is generally accepted that the high phenotypic diversity of mammals is a combined result of developmental constraint and ecological adaptation, although the influence of these endogenous and exogenous factors varies in different mammal groups. The rodent family Sciuridae represents an ideal candidate for examining phenotypic diversity in relation to phylogeny and ecological adaptations. In the present study, we investigate the effects of phylogeny and lifestyle on the skull shape in different species of Sciuridae by applying geometric morphometric methods.

The average concentrations of chromium, lead, copper, nickel, and zinc were generally lower in paddy rice soil relative to corn field soil. Soil under corn field production was slightly contaminated with lead (22-100 mg/kg), copper (31-64 mg/kg), and nickel (22-76 mg/kg) and moderately contaminated with zinc (112-635 mg/kg).
