A novel strategy for detoxification of deoxynivalenol via modification of both toxic groups.

Deoxynivalenol (DON) is the most abundant mycotoxin in cereal crops and derived foods and is of great concern in agriculture. Bioremediation strategies have long been sought to minimize the impact of mycotoxin contamination, but few direct and effective enzyme-catalyzed detoxification methods are currently available. In this study, we established a multi-enzymatic cascade reaction and successfully achieved detoxification at double sites: glutathionylation for the C-12,13 epoxide group and epimerization for the C-3 hydroxyl group.

Fhb7-GST catalyzed glutathionylation effectively detoxifies the trichothecene family.

Trichothecene (TCN) contamination in food and feed is a serious challenge due to the negative health and economic impacts. Here, we confirmed that the glutathione S-transferase (GST) Fhb7-GST could broadly catalyze type A, type B and type D TCNs into glutathione epoxide adducts (TCN-13-GSHs). To evaluate the toxicity of TCN-13-GSH adducts, we performed cell proliferation assays in vitro, which demonstrated decreased cytotoxicity of the adducts.

Gut metagenomic characteristics of ADHD reveal low -associated host cognitive impairment.

Attention-deficit/hyperactivity disorder (ADHD) is a highly heterogeneous psychiatric disorder that can have three phenotypical presentations: inattentive (I-ADHD), hyperactive-impulsive (HI-ADHD), and combined (C-ADHD). Environmental factors correlated with the gut microbiota community have been implicated in the development of ADHD. However, whether different ADHD symptomatic presentations are associated with distinct microbiota compositions and whether patients could benefit from the correction of aberrant bacterial colonization are still largely unclear.

Wheat genomic study for genetic improvement of traits in China.

Bread wheat (Triticum aestivum L.) is a major crop that feeds 40% of the world's population. Over the past several decades, advances in genomics have led to tremendous achievements in understanding the origin and domestication of wheat, and the genetic basis of agronomically important traits, which promote the breeding of elite varieties.

Wheat- Substitution Lines Imprint Compensation Both From Recipients and Donors.

Even frequently used in wheat breeding, we still have an insufficient understanding of the biology of the products distant hybridization. In this study, a transcriptomic analysis was performed for six - substitution lines in comparison with the host plants. All the six disomic substitution lines showed much stronger "transcriptomic-shock" occurred on alien genomes with 57.

Correlation between the salivary microbiology and H S concentration of the oral cavity.

Genome-wide identification, characteristics and expression of the prolamin genes in Thinopyrum elongatum.

Background: Prolamins, unique to Gramineae (grasses), play a key role in the human diet. Thinopyrum elongatum (syn. Agropyron elongatum or Lophopyrum elongatum), a grass of the Triticeae family with a diploid E genome (2n = 2x = 14), is genetically well-characterized, but little is known about its prolamin genes and the relationships with homologous loci in the Triticeae species.

Nutrigenomics reveals potential genetic underpinning of diverse taste preference of Chinese men.

Background: Taste preference varies geographically in China. However, studies on Chinese people's taste preference in different regions of China are limited, and are lack of research on the mechanism of differences in taste preference, especially in genetics.

Objective: This study aims to investigate the characteristics of taste preference of Chinese men, and estimate whether diverse taste preference in Chinese have genetic underpinning.

Comparative Analysis of the Glutathione S-Transferase Gene Family of Four Species and Transcriptome Analysis of GST Genes in Common Wheat Responding to Salt Stress.

Glutathione S-transferases (GSTs) are ancient proteins encoded by a large gene family in plants, which play multiple roles in plant growth and development. However, there has been little study on the GST genes of common wheat () and its relatives (, , and ), which are four important species of . Here, a genome-wide comprehensive analysis of this gene family was performed on the genomes of common wheat and its relatives.

Metabolomics and gene expression analysis reveal the accumulation patterns of phenylpropanoids and flavonoids in different colored-grain wheats (Triticum aestivum L.).

Colored-grain wheats have received increasing attention owing to their high nutritional values. In this study, we compared the metabolomes of four pigmented wheat cultivars with conventional yellow wheat using an ultra-performance liquid chromatography-electrospray ionization-tandem mass spectrometry (UPLC-ESI-MS/MS)-based metabolomics approach. A total of 711 metabolites were identified, and considerable differences were observed in the flavonoid and phenylpropanoid metabolites among five samples by orthogonal signal correction and partial least squares-discriminant analysis (OPLS-DA) analysis.

Distinct nucleotide patterns among three subgenomes of bread wheat and their potential origins during domestication after allopolyploidization.

Background: The speciation and fast global domestication of bread wheat have made a great impact on three subgenomes of bread wheat. DNA base composition is an essential genome feature, which follows the individual-strand base equality rule and [AT]-increase pattern at the genome, chromosome, and polymorphic site levels among thousands of species. Systematic analyses on base compositions of bread wheat and its wild progenitors could facilitate further understanding of the evolutionary pattern of genome/subgenome-wide base composition of allopolyploid species and its potential causes.

Horizontal gene transfer of from fungus underlies head blight resistance in wheat.

head blight (FHB), a fungal disease caused by species that produce food toxins, currently devastates wheat production worldwide, yet few resistance resources have been discovered in wheat germplasm. Here, we cloned the FHB resistance gene by assembling the genome of , a species used in wheat distant hybridization breeding. encodes a glutathione S-transferase (GST) and confers broad resistance to species by detoxifying trichothecenes through de-epoxidation.

Molecular Dissection of TaLTP1 Promoter Reveals Functional Cis-Elements Regulating Epidermis-Specific Expression.

Plant epidermis serves important functions in shoot growth, plant defense and lipid metabolism, though mechanisms of related transcriptional regulation are largely unknown. Here, we identified elements specific to shoot epidermis expression by dissecting the promoter of Triticum aestivum lipid transfer protein 1 (). A preliminary promoter deletion analysis revealed that a truncated fragment within 400 bp upstream from the translation start site was sufficient to confer conserved epidermis-specific expression in transgenic and .

High-throughput sequencing reveals the diversity of TCR β chain CDR3 repertoire in patients with severe acne.

Acne is a common chronic inflammatory skin disease, and the inflammation immune response runs through all stages of acne lesions. In this study, we use a combination of multiplex-PCR and high-throughput sequencing technologies to analyze T cell receptor β chain CDR3 (complementarity-determining region 3) in peripheral blood isolated from severe acne patients. Once compared with healthy controls, we propose to identify acne-relevant CDR3 peptides.

A Clostridia-rich microbiota enhances bile acid excretion in diarrhea-predominant irritable bowel syndrome.

An excess of fecal bile acids (BAs) is thought to be one of the mechanisms for diarrhea-predominant irritable bowel syndrome (IBS-D). However, the factors causing excessive BA excretion remain incompletely studied. Given the importance of gut microbiota in BA metabolism, we hypothesized that gut dysbiosis might contribute to excessive BA excretion in IBS-D.
