Molecular insights into the catabolism of dibutyl phthalate in Pseudomonas aeruginosa PS1 based on biochemical and multi-omics approaches.

A comprehensive understanding of the molecular mechanisms underlying microbial catabolism of dibutyl phthalate (DBP) is still lacking. Here, we newly isolated a bacterial strain identified as Pseudomonas aeruginosa PS1 with high efficiency of DBP degradation. The degradation ratios of DBP at 100-1000 mg/L by this strain reached 80-99 % within 72 h without a lag phase.

Multistable dynamics and attractors self-reproducing in a new hyperchaotic complex Lü system.

Multistable dynamics analysis of complex chaotic systems is an important problem in the field of chaotic communication security. In this paper, a new hyperchaotic complex Lü system is proposed and its basic dynamics are analyzed. Owing to the introduction of complex variables, the new system has some structurally distinctive attractors, such as flower-shaped and airfoil-shaped attractors.

Comprehensive profiling of alternative splicing landscape during secondary dormancy in oilseed rape ( L.).

Unlabelled: Alternative splicing is a general mechanism that regulates gene expression at the post-transcriptional level, which increases the transcriptomic diversity. Oilseed rape ( L.), one of the main oil crops worldwide, is prone to secondary dormancy.

Enhancing the quality of steamed oat cake by partially gelatinized starch in oat flour and its molecular mechanism.

The aim of this study was to investigate the effect and mechanism of partially gelatinized starch in oat flour on the rheological characteristics of the oat batter and the quality of steamed oat cakes. The results showed that an increase in the gelatinization degree of oat flour destroyed the starch granular structure and the long-range molecular order of starch, accompanied by a decrease of crystallinity from 22.28 % to 8.

Effects of gelatinization degree and boiling water kneading on the rheology characteristics of gluten-free oat dough.

The effects of gelatinization degree of oat flour and boiling water on the rheological characteristics of oat dough were investigated. Gelatinized oat flour had higher water absorption (2.25-3.

QTL mapping and candidate gene analysis of low temperature germination in rice ( L.) using a genome wide association study.

Low temperature germination (LTG) is a key agronomic trait in rice ( L.). However, the genetic basis of natural variation for LTG is largely unknown.

Similar Bacterial Communities among Different Populations of a Newly Emerging Invasive Species, (Meyrick).

Microorganisms in the guts of insects enhance the adaptability of their hosts with different lifestyles, or those that live in different habitats. is an invasive pest that is a serious threat to tomato production in China. It has quickly spread and colonized Xinjiang, Yunnan and other provinces and regions.

Fine-Tuning of the Grain Size by Alternative Splicing of GS3 in Rice.

Grain size is subtly regulated by multiple signaling pathways in rice. Alternative splicing is a general mechanism that regulates gene expression at the post-transcriptional level. However, to our knowledge, the molecular mechanism underlying grain size regulation by alternative splicing is largely unknown.

Functional Characterization of a Novel Heterozygous Mutation in the Glucokinase Gene That Causes MODY2 in Chinese Pedigrees.

Background: Glucokinase (GCK) plays a central role in glucose regulation. The heterozygous mutations of can cause a monogenic form of diabetes, maturity-onset diabetes of the young (MODY) directly. In our study, we aimed to explore the mechanism of the novel mutation p.

Changes of aggregation and structural properties of heat-denatured gluten proteins in fast-frozen steamed bread during frozen storage.

The aim of this research was to clearly clarify the deterioration mechanism of heat-denatured gluten proteins by exploring the change of aggregation and structural characteristics of heat-denatured gluten proteins in the steamed bread system and the steamed gluten system during frozen storage. An increase in the total SDS-soluble protein content was determined, which mainly attributed to the soluble monomer protein content increased. Combined with the significant increase of free sulfhydryl, from 3.

Bacterial diversity in ballast water and sediments revealed by 2b-RAD sequencing.

Despite that the ballast water management (BWM) convention has come into force to prevent the spread of harmful aquatic organisms, to date, very few bacteria can be identified through microbial culture method. In this study, we explored a reduced-representation sequencing of 2b-RAD approach to investigate the bacterial diversity in ballast water and sediments (BWS). Our results indicated a large amount of bacteria species (1496) detected in BWS up to now, including 13 pathogens that are seriously concerning in marine environment and aquaculture like the most harmful Vibrio harveyi and Aurantimonas coralicida.

Normal, novel or none: versatile regulation from alternative splicing.

Pre-mRNA splicing is a vital step in the posttranscriptional regulation of gene expression. Splicing is catalyzed by the spliceosome, a multidalton RNA-protein complex, through two successive transesterifications to yield mature mRNAs. In Arabidopsis, more than 61% of all transcripts from intron-containing genes are alternatively spliced, thereby resulting in transcriptome and subsequent proteome diversities for cellular processes.

Cerium-Based Metal-Organic Framework Nanocrystals Interconnected by Carbon Nanotubes for Boosting Electrochemical Capacitor Performance.

In this study, nanocrystals of a cerium-based metal-organic framework (Ce-MOF), Ce-MOF-808, are directly grown on the surface of carboxylic acid-functionalized carbon nanotubes (CNTs) by a facile one-step solvothermal synthesis method. Ce-MOF-CNT nanocomposites with various Ce-MOF-to-CNT ratios are synthesized, and their crystallinity, morphology, porosity, and electrical conductivity are examined. The redox-hopping and electrochemical behaviors of the pristine Ce-MOF in aqueous electrolytes are investigated, suggesting that the pristine Ce-MOF is electrochemically active but possesses a limited charge-transport behavior.

Selective Formation of Polyaniline Confined in the Nanopores of a Metal-Organic Framework for Supercapacitors.

In this study, a strategy that can result in the polyaniline (PANI) solely confined within the nanopores of a metal-organic framework (MOF) without forming obvious bulk PANI between MOF crystals is developed. A water-stable zirconium-based MOF, UiO-66-NH , is selected as the MOF material. The polymerization of aniline is initiated in the acidic suspension of UiO-66-NH nanocrystals in the presence of excess poly(sodium 4-styrenesulfonate) (PSS).
