Summary: This study investigated two cultivars of Brassica crops, purple flowering stalk and pakchoi, and found that the purple flowering stalk has a higher level of anthocyanin compared to pakchoi. The study also identified several structural genes and regulatory genes that are involved in the accumulation of anthocyanin, as well as the interactions between these genes. The findings lay a foundation for further research on anthocyanin accumulation in Brassica crops.

Summary: In this study, 157 anthocyanin biosynthesis related genes (ABGs) were identified in B. napus genome. Five anthocyanins were identified in the stem bark and leaves of purple B. napus PR01. The up-regulation of transcript factors BnaA07.PAP2 and BnaC06.PAP2 were identified as key to the up-regulation of most of anthocyanin synthesis genes in PR01.

Summary: In this study, a COP1-interacting protein-encoding gene, SmCIP7, was identified and characterized in eggplant. Silencing of SmCIP7 altered fruit coloration, size, flesh browning, and seed yield. The study showed that SmCIP7 promotes anthocyanin accumulation by regulating the transcription of SmTT8, and the up-regulation of the homologous gene SmYABBY1 may contribute to the fruit growth retardation in SmCIP7-RNAi eggplant.

Summary: Plants accumulate triacylglycerol in vegetative tissues under stress conditions by activating key transcription factors regulating seed triacylglycerol biosynthesis to enhance plant tolerance to environmental stresses. This metabolic reprogramming is driven by transcriptional regulation, involving both seed maturation program derepression and stress-induced transcription factors activation, linking TAG biosynthesis with plant survival in adverse environments.

Summary: Metabolome and transcriptome profiles of freezing-tolerant and freezing-sensitive kiwifruit genotypes were studied under cold stress, revealing specific upregulation of flavonoid metabolic pathways in the tolerant genotype KL and nucleotides metabolism pathways in the sensitive genotype RB. Key metabolism components were found to participate in the regulation of freezing tolerance in both genotypes.

Summary: Anthocyanins in purple shamrock were characterized, and the molecular mechanism of anthocyanin biosynthesis was investigated using RNA-seq and qRT-PCR. The study revealed that most of the anthocyanin biosynthetic and regulatory genes were up-regulated in purple shamrock, and both light and low temperature could induce anthocyanin biosynthesis.

Summary: A simple acetonitrile-based extraction method using HPLC-ESI-MS/MS was developed for the determination of 98 current-use pesticides in soil and herbaceous vegetation. The method exhibited good accuracy and precision, with percentage recoveries ranging from 71-125% (soil) and 70-117% (vegetation), and relative standard deviations of 1-14% (soil) and 1-13% (vegetation). Matrix-matched calibration curves showed excellent linearity (R-2 > 0.99). The method was successfully applied to agricultural sites in Germany, where 44 of the 98 pesticides were detected, indicating a high qualitative load compared to EU arable soils.

Summary: Anthocyanins were characterized in red cabbage, sweet potato, and Tradescantia pallida leaves. Various non-, mono-, and diacylated cyanidins were identified in red cabbage. Sweet potato leaves contained mono- and diacylated cyanidin- and peonidin glycosides, while T. pallida leaves mainly contained tetra-acylated anthocyanin tradescantin. The thermal stability of red cabbage and purple sweet potato extracts surpassed that of a commercial food dye, but still fell short compared to the stability of Tradescantia extract.

Summary: The distribution of Se and Hg in different protein fractions extracted from muscle tissues of tuna, swordfish, and salmon (wild vs. farmed) was investigated for the first time. The study revealed that Se and Hg were associated with proteins of specific molecular weights, with differences observed between farmed and wild salmon. Additionally, Se speciation studies showed SeMeSeCys as the primary selenium species found in the proteins analyzed.

Summary: This study investigated fifteen commonly consumed purple vegetables for their total anthocyanins, anthocyanidins, profile of anthocyanins, and antioxidant abilities. The results showed that black carrot had the highest antioxidant ability, followed by red cabbage, red cowpea, and purple cauliflower. Purple vegetables with high contents of total anthocyanins exhibited high antioxidant abilities.

Summary: An orthogonal L(16)4(3) x 2(2) test design was used to optimize the extraction of flavan-3-ols in grape seeds. The optimized HPLC method separated and identified fourteen flavan-3-ols, showing that the new wine grape - Beihong, had higher flavan-3-ols content and polymerization compared to classic wine grapes like Cabernet Sauvignon, Merlot, Semillon, and Riesling.

Summary: In this study, the photostability of felodipine (FL) medicine and its altered forms was evaluated. The residual amounts of FL after 24 h of UV irradiation were measured and two photoproducts were identified. The chemical structures of the photoproducts were determined using mass spectrometry analysis. The generation rates of the photoproducts were found to be dependent on the presence of aqueous media.
