After functional category enrichment analysis of differential expression genes (DEGs), 25 genes were selected as the candidate genes related to anthocyanin accumulation. Furthermore, the expression patterns of some selected DEGs were verified by quantitative real-time PCR (qRT-PCR), and the correlation between expression levels of relevant genes involved in anthocyanin biosynthesis and anthocyanin content was determined. Taken together, the results compose a transcriptomic analysis to investigate the differences in purple flesh formation in the storage roots among different sweetpotato varieties, with the notable outcome that several key genes can now be closely linked to anthocyanin biosynthesis.Lotus is an important aquatic ornamental plant, whose flower color is one of the key horticultural traits that determines its ornamental value. Previous studies revealed that anthocyanins largely determined the red color of lotus flower, which are also the main component that has beneficial effects on human health. However, the regulation mechanism of flower pigmentation in lotus flower remains unclear. In the present study, in order to further understand the regulatory mechanism underlying the anthocyanin biosynthesis, a bHLH gene NnTT8 was characterized to be phylogenetically close to AtTT8 and the bHLH proteins from other plant species that have been indicated to be involved in the positive regulation of anthocyanin biosynthesis. Complementation analysis in Arabidopsis tt8 mutant showed that NnTT8 could function similarly to AtTT8 in regulating anthocyanin and proanthocyanin biosynthesis. An MYB transcription factor capable of interacting with NnTT8 was also characterized from lotus. The identification of a bHLH transcription factor playing regulatory roles in anthocyanin biosynthesis is crucial, as it might help to obtain more in-depth insight into the coloration of lotus and help in breeding high anthocyanin content lotus variety that can be explored for lotus flower beverages.A novel method for hierarchical screening of illegal adulterants in Fur seal ginseng pills (FSGP) products was developed by microwave-assisted extraction (MAE) coupled to salting-out assisted liquid-liquid extraction (SALLE) with multi-dimensional fingerprint profiling analysis. Using a homogeneous system formed by dimethyl carbonate (DMC) and water as the extractant, the MAE conditions were investigated to maximize extraction recoveries, followed by addition of ammonium sulfate to induce DMC phase separation for SALLE enrichment of 16 potentially illegal adulterants such as phosphodiesterase type-5 inhibitors, androgens, α receptor antagonists and yohimbine etc. By means of high-performance liquid chromatography (HPLC) with diode array detection (DAD) and fluorescence detection (FLD), multi-dimensional fingerprints were acquired by multi-wavelength detection to highlight the signals of the potentially illegal adulterants and reduce or remove interferences from the sample matrix. For high accuracy and reliability, a hierarchical screening strategy was designed by multi-dimensional fingerprinting profiling analysis (MDFPA). The method exhibited proper identification and quantification performance, and it was successfully applied to screening of illegal adulterants in 18 batches of the samples through the step-by-step MDFPA. Also, the results were further confirmed by ultra high-performance liquid chromatography-quadrupole-orbitrap mass spectrometry (UHPLC-Q-Orbitrap/MS). The proposed method was proved to be a green, efficient and reliable alternative to monitoring aphrodisiac health products.The study of insect-associated microbial communities is a field of great importance in agriculture, principally because of the role insects play as pests. In addition, there is a recent focus on the potential of the insect gut microbiome in areas such as biotechnology, given some microorganisms produce molecules with biotechnological and industrial applications, and also in biomedicine, since some bacteria and fungi are a reservoir of antibiotic resistance genes (ARGs). To date, most studies aiming to characterize the role of the gut microbiome of insects have been based on high-throughput sequencing of the 16S rRNA gene and/or metagenomics. However, recently functional approaches such as metatranscriptomics, metaproteomics and metabolomics have also been employed. Besides providing knowledge about the taxonomic distribution of microbial populations, these techniques also reveal their functional and metabolic capabilities. This information is essential to gain a better understanding of the role played by microbes comprising the microbial communities in their hosts, as well as to indicate their possible exploitation. This review provides an overview of how far we have come in characterizing insect gut functionality through omics, as well as the challenges and future perspectives in this field.Protein binding determination for highly-bound compounds using equilibrium dialysis remains a challenge in drug discovery. The reasons are mainly three-fold; 1. due to their slow diffusion rate, highly-bound compounds require a much longer incubation time to reach dialysis equilibrium than typically needed; 2. highly-bound compounds are often hydrophobic and prone to non-specific binding in dialysis; 3. free drug concentration in the post incubation dialysate is too low for reliable analytical quantification. LY3023414 cell line Modified equilibrium dialysis approaches include using diluted plasma for dialysis, or pre-saturating the non-specific binding sites in the dialysis device with compounds of interest prior to dialysis. In this study, we developed a customized equilibrium dialysis assay with an extended incubation time of 24 h, followed by microflow (μF) LC-MS/MS for bioanalysis, for direct and definitive free fraction determination of highly protein-bound compounds. The extended incubation time ensured the dialysis to reach equilibrium and saturating the non-specific binding sites, while μFLC-MS/MS provided far better sensitivity than the conventional LC-MS/MS typically used for post incubation bioanalysis. For a group of commercially available, highly protein-bound compounds, the free fraction data generated by the developed assay correlated very well with the literature values generated with diluted plasma method or pre-saturation method. This novel assay approach has been successfully used to generate protein binding results for highly-bound compounds to support ongoing drug discovery research.
