Transcriptome and metabolome analyses reveal the promoting effects of arbuscular mycorrhizal fungi on selenium uptake in grapevines.

To improve the selenium (Se) uptake in grapes, the effects of arbuscular mycorrhizal fungi (AMF) on the Se accumulation in grapevines were studied under a soil Se concentration of 5 mg/kg, and the transcriptome and metabolome sequencing were used to elucidate the regulatory mechanism of AMF on Se accumulation. AMF initially decreased the biomass of grapevines, but later increased the biomass. Moreover, AMF enhanced the activities of Se metabolism enzymes (adenosine triphosphate sulfurylase, adenosine 5'-phosphosulfate reductase, serine acetyltransferase, and cysteine methyltransferase) and the Se concentration in grapevines.

In Situ Column Modification of Silica Monoliths With Pentafluorophenyl Ligands for the HPLC Separation of Eight Tocochromanols.

Silica-based monoliths offer higher separation efficiency per unit pressure drop compared to particle-packed columns. Their application is limited by the commercial availability of different column chemistries. Pentafluorophenyl ligands enable hydrogen bonding, dipole-dipole, π-π, and hydrophobic interactions, facilitating the separation of various compounds.

In recent years, its cultivation areas have changed significantly, resulting in mixed quality of the medicinal herbs. In this study, Gongju cultivated in Anhui, Yunnan, Chongqing, and other places were selected as research objects.

Impact of conventional and innovative processing conditions on organoleptic and nutritional properties of applesauce from organic and conventional production systems.

The impact of cultivar and production system was studied over two years on organoleptic and nutritional characteristics of apple fruits and then, on purees processed with both conventional convection cooking under vacuum and fast innovative microwave cooking. The main factors affecting the content and composition of sugars, organic acids, volatiles, polyphenols, and fibre were in the decreasing order, cultivar, year, and production system. Regarding processing, the fast innovative microwave cooking led to puree with a higher viscosity but with a lower polyphenol content compared to the convection cooking.

Enhancing Antimicrobial Efficacy of Sandalwood Essential Oil Against for Food Preservation.

The growing emphasis on food safety and healthier lifestyles, driven by industrial expansion and scientific priorities, has highlighted the necessity of managing harmful microorganisms to guarantee food quality.

Essential oils, renowned for their antibacterial properties, present a promising natural alternative for food preservation.

Evaluation of Quality of Nitrite-Free Fermented Roe Deer () Sausage with Addition of Ascorbic Acid and Reduced NaCl.

This study aimed to investigate the possibility of producing fermented roe deer sausages using acid whey without the addition of sodium nitrite. Additionally, ascorbic acid was added to improve the oxidative stability of the product, and sodium chloride (NaCl) was partially replaced by potassium chloride (KCl) (7:3). The sausages were analyzed after fermentation (on day 30) and during post-production aging (i.

gene integration into regulatory networks via interaction with conserved genes in peach.

genes can evolve "from scratch" from noncoding sequences, acquiring novel functions in organisms and integrating into regulatory networks during evolution to drive innovations in important phenotypes and traits. However, identifying genes is challenging, as it requires high-quality genomes from closely related species. According to the comparison with nine closely related genomes, we determined at least 178 genes in "baifeng".

OHDLF: A Method for Selecting Orthologous Genes for Phylogenetic Construction and Its Application in the Genus .

Accurate phylogenetic tree construction for species without reference genomes often relies on de novo transcriptome assembly to identify single-copy orthologous genes. However, challenges such as whole-genome duplication (WGD), heterozygosity, gene duplication, and loss can hinder the selection of these genes, leading to limited data for constructing reliable species trees. To address these issues, we developed a new analytical pipeline, OHDLF (Orthologous Haploid Duplication and Loss Filter), which filters orthologous genes from transcript data and adapts parameter settings based on genomic characteristics for further phylogenetic tree construction.
