Wastewater treatment processes are of growing interest as a potential means to limit the dissemination antibiotic resistance. This study examines response nine representative resistance genes (ARGs) encoding sulfonamide (sulI, sulII), erythromycin (erm(B), erm(F)), and tetracycline (tet(O), tet(W), tet(C), tet(G), tet(X)) various laboratory-scale sludge digestion processes. The class I integron gene (intI1) was also monitored an indicator horizontal transfer multiple Mesophilic anaerobic at...

Summary Moso bamboo is a large, woody with the highest ecological, economic and cultural value of all types accounts for up to 70% total area grown. However, spatiotemporal variation role moso shoot during growth period still unclear. We found that can be divided into three distinct periods, including winter growth, early late based on gene expression anatomy. In period, lateral buds germinated from top joint in tip. Intercalary meristems grew vigorously but mitosis intercalary decreased....

Summary Microbial populations provide nitrogen cycling ecosystem services at the nexus of agriculture, environmental quality and climate change. Denitrification, in particular, impacts socio‐environmental systems both positive negative ways, through reduction aquatic atmospheric pollution, but also soil fertility production greenhouse gases. However, denitrification rates are quite variable time space, therefore difficult to model. ecology is working improve predictive denitrifiers by...

Salinity is a major environmental factor that adversely affects plant growth and production. Cuticular wax protects plants against external stress. The relationship between cuticular biosynthesis salt tolerance remains unclear in Salicornia europaea. This study examined the cuticle thickness, load, morphology, composition, expression of gene identification expression. results showed 600 mM NaCl treatment enhanced thickness total load; crystal structures were also observed after treatment....

This study investigated the response of antibiotic resistance genes (ARGs) to nanosilver (Ag) in lab-scale nitrifying sequencing batch reactors (SBRs), compared Ag+-dosed and undosed controls. Quantitative polymerase chain reaction (q-PCR) targeting sul1, tet(O), ermB class I integron gene intI1 corresponding RNA expression did not indicate measureable effects nanoAg or Ag+ on abundance these genes. However, high-throughput based metagenomic analysis provided a much broader profile responses...

Salicornia europaea is a halophyte that has very pronounced salt tolerance. As cell wall manipulating enzyme, xyloglucan endotransglycosylase/hydrolase (XTH) plays an important role in plant resistance to abiotic stress. However, no systematic study of the XTH gene family S. well known. PacBio Iso-Seq transcriptome sequence data were used for bioinformatics and expression analysis using real-time quantitative polymerase chain reaction (RT-qPCR).Transcriptome sequencing (PacBio system)...

This study assesses the oxidative potential, cytotoxicity, and genotoxicity of particulate matter produced from incineration a variety nanomaterials in waste.

MADS-box genes are transcription factors which play fundamental roles in flower development and regulation of floral organ identity. However, till date, identification functions remain largely unclear Phyllostachys edulis. In view this, we performed a whole-genome survey identified 34 P. edulis, based on phylogeny, they were classified as MIKCC, MIKC*, Mα Mβ. The detailed analysis about gene structure motifs, phylogenetic classification, comparison divergence duplication provided....

Lignin is a plant heteropolymer composed of phenolic subunits. Because its heterogeneity and recalcitrance, the development efficient methods for valorization still remains an open challenge. One approach to utilize lignin chemical deconstruction into mixtures monomeric compounds followed by biological funneling single product. Novosphingobium aromaticivorans DSM12444 has been previously engineered produce 2-pyrone-4,6-dicarboxylic acid (PDC) from depolymerized simultaneously metabolizing...

Abstract Background: The microbial symbionts of macrofungal fruiting body have been shown to play momentous roles in host growth, development, and secondary metabolism. Nevertheless, there is no report on the fungal diversity Sanghuangporus , a medicinal edible homologous macrofungus as “forest gold”, which has good effects antioxidation, boosting immunity curing stomachache. Here, functional group fungi associated with most widely applied S. vaninii were characterized by high-throughput...

Fruit development in Lycium ruthenicum Murr. involves a succession of physiological and biochemical changes reflecting the transcriptional modulation thousands genes. Although recent studies have investigated dynamic transcriptomic responses during fruit ripening L. ruthenicum, most been limited scope, thus systematic data representing structural genes transcription factors involved anthocyanin biosynthesis are lacking. In this study, transcriptomes three stages associated with accumulation,...

The Dof transcription factor (TF) family belongs to a class of plant-specific TFs and is involved in plant growth, development, response abiotic stresses. However, there are only very limited reports on the characterization moso bamboo (Phyllostachys edulis). In present research, PheDof showed specific expression profiles based RNA-seq data analyses. co-expression network indicated that PheDof12, PheDof14, PheDof16 might play vital roles during flower development. Cis-regulatory element...

Lignin is the most abundant aromatic polymer on Earth and a resource that could eventually substitute for fossil fuels as source of compounds industrial biotechnological applications. Engineering microorganisms production aromatic-based biochemicals requires detailed knowledge metabolic pathways degradation aromatics are present in lignin.
