Effects of organic fertilization on functional microbial communities associated with greenhouse gas emissions in paddy soils.

Soil microbial communities play a key role in the biochemical processes and nutrient cycles of the soil ecosystem and their byproducts, including greenhouse gases (GHGs). Organic fertilization influences bacterial soil biodiversity and is an essential emission source of GHGs in paddy soil ecosystems. However, the impact of organic fertilization on the functional microorganisms associated with the GHGs methane and nitrous oxide remains unknown.

The Modulatory Effect of Flavonoids on Intestinal Microbiota and Hypothalamus Clock Genes in a Circadian Rhythm Disorder Mouse Model.

Circadian rhythm disruption is detrimental and results in adverse health consequences. We used a multi-omics profiling approach to investigate the effects of flavonoid (CPF)-enriched diets on gut microbiota, metabolites, and hypothalamus clock genes in mice with induced circadian rhythm disruption. It was observed that CPF supplementation altered the specific composition and function of gut microbiota and metabolites induced by circadian rhythm disruption.

Research on the Operating Mechanism of E-Commerce Poverty Alleviation in Agricultural Cooperatives: An Actor Network Theory Perspective.

E-commerce poverty alleviation has become a new wisdom in China's rural poverty alleviation, but there are a few empirical researches on e-commerce poverty alleviation based on farmer cooperatives. Taking four typical poverty counties in Zhejiang Province as an example, based on the actor network theory (ANT), this paper defines the participants and their obligatory passage point (OPP) from the e-commerce poverty alleviation actor network (EPAAN), combs the roles and interest demands of various stakeholders, and constructs the EPAAN model based on farmer cooperatives according to the translation process. We found that the EPAAN is a heterogeneous network by constantly updating, which consists of human actors with cooperatives as the main body and non-human actors.

Genome-wide association studies and haplotype sharing analysis targeting the growth traits in Yandang partridge chickens.

The body size of a chicken is an economically important trait as it directly influences the benefits of the poultry industry, but the relevant genetic mechanisms have not yet been elucidated. In this study, we measured eight growth traits for 94 Yandang partridge chickens, then undertook genome-wide association studies (GWAS) for those traits in using a linear mixed model based on 10× whole genomic sequencing data to better understand the knowledge of the genetic architecture of growth traits. Ninety-four individuals and 7647883 SNPs remained after quality control and removal of the sex chromosomes, and these data were used to carry out a GWAS analysis.

Microplastics in the soil: A review of distribution, anthropogenic impact, and interaction with soil microorganisms based on meta-analysis.

Microplastics (MPs) are widespread anthropogenic pollutants that contaminate the terrestrial environment and serve as vectors of other contaminants. They trigger toxic effects during their migration and transmission, affecting the soil ecosystem and eventually presenting a serious threat to human health via the food chain. However, comprehensive studies on the distribution of MPs in soil and their correlation with human activities and terrestrial ecosystems are still lacking.

Sequential Production of ᴅ-xylonate and Ethanol from Non-Detoxified Corncob at Low-pH by via a Two-Stage Fermentation Strategy.

Improving the comprehensive utilization of sugars in lignocellulosic biomass is a major challenge for enhancing the economic viability of lignocellulose biorefinement. A robust yeast N-X showed excellent performance in ethanol production under high temperature and low pH conditions and was engineered for ᴅ-xylonate production without xylitol generation. The recombinant strain N-X/S1 was employed for sequential production of ᴅ-xylonate and ethanol from ᴅ-xylose, feeding on ᴅ-glucose without pH control in a two-stage strategy of aerobic and shifting micro-aerobic fermentation.

Nitrogen-doped biochar as peroxymonosulfate activator to degrade 2,4-dichlorophenol: Preparation, properties and structure-activity relationship.

Sheath blight resistance in rice is negatively regulated by WRKY53 via SWEET2a activation.

Sheath blight (ShB) is one of the most common diseases in rice that significantly affects yield production. However, the underlying mechanisms of rice defense remain largely unknown. Our previous transcriptome analysis identified that infection with Rhizoctonia solani significantly induced the expression level of SWEET2a, a member of the SWEET sugar transporter.

Physiological and transcriptional responses of Dictyosphaerium sp. under co-exposure of a typical microplastic and nonylphenol.

Microplastics (MPs) and nonylphenol (NP) are typical pollutants that are frequently detected in aquatic environments and can pose a risk to aquatic organisms. However, the responses of algae, the producers in aquatic ecosystems, to MP and NP co-exposure have not been extensively investigated. In this study, polystyrene (PS, 50 mg/L) was selected as a representative MP to evaluate its short-term effects on algae treated with NP (4 mg/L).

Nanoscale zero-valent iron alters physiological, biochemical, and transcriptomic response of nonylphenol-exposed algae (Dictyosphaerium sp.).

Nanoparticles and organic pollutants are two major contaminants found in aquatic environments. Algae are regarded as the model organism for the risk assessment of pollutants in water. In our previous study, we investigated the toxic effects of nonylphenol (NP), a typical organic water pollutant, on algae; however, it remains unclear how algae respond to the coexistence of NP and nanoparticles.

NB-LRR genes: characteristics in three Solanum species and transcriptional response to Ralstonia solanacearum in tomato.

Genetic dissection of heterosis of indica-japonica by introgression line, recombinant inbred line and their testcross populations.

The successful implementation of heterosis in rice has significantly enhanced rice productivity, but the genetic basis of heterosis in rice remains unclear. To understand the genetic basis of heterosis in rice, main-effect and epistatic quantitative trait loci (QTLs) associated with heterosis for grain yield-related traits in the four related rice mapping populations derived from Xiushui09 (XS09) (japonica) and IR2061 (indica), were dissected using single nucleotide polymorphism bin maps and replicated phenotyping experiments under two locations. Most mid-parent heterosis of testcross Fs (TCFs) of XS09 background introgression lines (XSILs) with Peiai64S were significantly higher than those of TCFs of recombinant inbred lines (RILs) with PA64S at two locations, suggesting that the effects of heterosis was influenced by the proportion of introgression of IR2061's genome into XS09 background.
