Abstract	The chemical composition of the secondary metabolites is of great significance to the quality control of agricultural products. The genus Dianthus is famous for its beautiful flowers in the cut flower trade and also used in the traditional Chinese medicinal system and food market. However, the chemical composition in Dianthus is still unknown. The current study examined the levels of different metabolites of the flowers in Dianthus caryophyllus, Dianthus chinensis and Dianthus superbus via the use of the widely targeted metabolomic strategy. We obtained the structure and content of 423 metabolites in Dianthus, which included the primary and secondary metabolites. The principal component analysis was able to clearly seperate Dianthus caryophyllus, Dianthus chinensis and Dianthus superbus based on the flower metabolites. The differential metabolites can be categorised into 11 different classes, the majority were flavonoids, amino acids and their derivatives, phenolic acids and lipids. The results of this study provide important information for the effective use of Dianthus flowers in edible, medicinal and therapeutic aspects.

Abstract	The crisis of arsenic (As) accumulation in rhizomes threatens the quality and safety of Panax notoginseng (Burk.) F.H. Chen, which is a well-known traditional Chinese herb with a long clinical history. The uptake of arsenate (AsV) could be suppressed by supplying phosphate (Pi), in which Pi transporters play important roles in the uptake of Pi and AsV. Herein, the P . notoginseng Pi transporter-encoding gene PnPht1;3 was identified and characterised under Pi deficiency and AsV exposure. In this study, the open reading frame (ORF) of PnPht1;3 was cloned according to RNA-seq and encoded 545 amino acids. The relative expression levels revealed that PnPht1;3 was significantly upregulated under phosphate deficiency and AsV exposure. Heterologous expression in Saccharomyces cerevisiae MB192 demonstrated that PnPht1;3 performed optimally in complementing the yeast Pi-transport defect and accumulated more As in the cells. Combined with the subcellular localisation prediction, it was concluded that PnPht1;3 encodes a functional plasma membrane-localised transporter protein that mediates putative high-affinity Pi/H+ symport activity and enhances the uptake of Pi and AsV. Therefore, a better understanding of the roles of the P . notoginseng Pi transporter could provide new insight for solving As accumulation in medicinal plants.

Abstract	Evidence accumulated in recent years supports the crucial role of remodeled cell walls (CWs) in enabling plants to adapt to environmental challenges. However, the metal tolerance and alleviation mechanisms involving the CWs by endophyte-plant interactions to toxic metals have not yet been elucidated. In the present study, these mechanisms are tested by exploring the maize (Zea mays) Cd tolerance by modifying its root CW structure via inoculation with a dark septate endophyte (DSE) fungus Exophiala pisciphila. Our present study demonstrates that the root CWs were the primary site for Cd accumulation, functioning as a sink for toxic Cd ions. Interestingly, E. pisciphila colonization significantly bioaugmented subcellular compartmentalization of maize roots and increased the Cd content of various CW subfractions through a significantly increased enzyme activity, e.g., pectin methylesterase, as well as an upregulated expression of genes involved in CW biosynthesis and changes in the contents of functional groups in pectin and hemicellulose 1 in response to Cd stress. Consequently, the enhanced Cd compartmentation in plant CWs by DSE lowers the entry of trace metals in the protoplast, thereby conferring the tolerant races of plants that can survive and thrive on metal-contaminated soils.

Abstract	The main purpose of this study was to reveal the nutritional value and antioxidant activity of 34 edible flowers that grew in Yunnan Province, China, through a comprehensive assessment of their nutritional composition and antioxidant indices. The results showed that sample A3 of Asteraceae flowers had the highest total flavonoid content, with a value of 8.53%, and the maximum contents of vitamin C and reducing sugars were from Rosaceae sample R1 and Gentianaceae sample G3, with values of 143.80 mg/100 g and 7.82%, respectively. Samples R2 and R3 of Rosaceae were the top two flowers in terms of comprehensive nutritional quality. In addition, the antioxidant capacity of Rosaceae samples was evidently better than that of three others, in which Sample R1 had the maximum values in hydroxyl radical (

Abstract	Enterovirus A71 (EV-A71) is a major pathogen that causes severe and fatal cases of hand-foot-and-mouth disease (HFMD), which is an infectious disease that endangers children's health. However, the pathogenic mechanisms underlying these severe clinical and pathological features remain incompletely understood. Metabolism and stress are known to play critical roles in multiple stages of the replication of viruses. Lipid metabolism and ER stress is an important characterization post viral infection. EV-A71 infection alters the perturbations of intracellular lipid homeostasis and induces ER stress. The characterizations induced by viral infections are essential for optimal virus replication and may be potential antiviral targets. In this study, we found that the addition of the chemical drug of ER stress, PKR IN, an inhibitor, or Tunicamycin, an activator, could significantly reduce viral replication with the decrease of lipid. The replication of viruses was reduced by Chemical reagent TOFA, an inhibitor of acetyl-CoA carboxylase (ACC) or C75, an inhibitor of fatty acid synthase (FASN), while enhanced by oleic acid (OA), which is a kind of exogenous supplement of triacylglycerol. The pharmacochemical reagent of carnitine palmitoyltransferase 1 (CPT1) called Etomoxir could knock down CPT1 to induce EV-A71 replication to decrease. This suggests that lipid, rather than ER stress, is the main factor affecting EV-A71 replication. In conclusion, this study revealed that it is the β-oxidation of lipid that plays a core role, not ER stress, which is only a concomitant change without restrictive effect, on virus replication.
