Metabolomics Analysis Reveals Major Differential Metabolites and Metabolic Alterations in Tea Plant Leaves (Camellia sinensis L.) Under Different Fluorine Conditions

Tea plant (Camellia sinensis L.) is capable of accumulating a large amount of fluorine (F) in leaves without showing toxicity symptoms and thus offers a good model for exploring F tolerance mechanisms. Here, gas chromatography time-of-flight mass spectrometry (GC-TOF?MS) was used to investigate metabolic changes in leaves of tea seedlings under control (0?mM), low F (0.2?mM) and high F (0.8?mM) conditions. Differentially changed metabolites such as galacturonic acid, lactose, fructose, malic acid, alanine were identified by the comparison among the three F treatment groups. A pathway map depicted based on the KEGG database reflected the involvement of pectin biosynthesis metabolism in F stress response. The gene expression and enzyme activity of key enzymes involved in pectin biosynthesis pathway and the content of pectic polysaccharides were increased by exogenous F treatments, indicating the promotion effect of F on the pectin biosynthesis. Pectin was also immunochemically stained in vivo using monoclonal antibody (2F4), which confirmed the increment. The increased pectin might contribute to combining the exogenous F in tea leaves. This research provided some novel insights into further research on F detoxification of plants.

Simple and Efficient Generation of Aryl Radicals from Aryl Triflates: Synthesis of Aryl Boronates and Aryl Iodides at Room Temperature

Despite the wide use of aryl radicals in organic synthesis, current methods to prepare them from aryl halides, carboxylic acids, boronic acids, and diazonium salts suffer from limitations. Aryl triflates, easily obtained from phenols, are promising aryl radical progenitors but remain elusive in this regard. Inspired by the single electron transfer process for aryl halides to access aryl radicals, we developed a simple and efficient protocol to convert aryl triflates to aryl radicals. Our success lies in exploiting sodium iodide as the soft electron donor assisted by light. This strategy enables the scalable synthesis of two types of important organic molecules, i.e., aryl boronates and aryl iodides, in good to high yields, with broad functional group compatibility in a transition-metal-free manner at room temperature. This protocol is anticipated to find potential applications in other aryl-radical-involved reactions by using aryl triflates as aryl radical precursors.

Halogenated indoles eradicate bacterial persister cells and biofilms

The emergence of antibiotic resistance has necessitated new therapeutic approaches to combat recalcitrant bacterial infections. Persister cells, often found in biofilms, are metabolically dormant, and thus, are highly tolerant to all traditional antibiotics and represent a major drug resistance mechanism. In the present study, 36 diverse indole derivatives were investigated with the aim of identifying novel compounds that inhibit persisters and biofilm formation by Gram-negative Escherichia coli and Gram-positive Staphylococcus aureus. 5-Iodoindole and other halogenated indoles, 4-fluoroindole, 7-chloroindole, and 7-bromoindole, eradicated persister formation by E. coli and S. aureus, and 5-iodoindole most potently inhibited biofilm formation by the two bacteria. Unlike other antibiotics, 5-iodoindole did not induce persister cell formation, and 5-iodoindole inhibited the production of the immune-evasive carotenoid staphyloxanthin in S. aureus; hence, 5-iodoindole diminished the production of virulence factors in this strain. These results demonstrate halogenated indoles are potentially useful for controlling bacterial antibiotic resistance.

3D tailored design as a bioremediation strategy for a lagoon in Matanza-Riachuelo basin

A native strain of the microalgae Chlorella vugaris was shown to be effective for the reduction of several chemical and microbial contaminants present in polluted streams from the Matanza-Riachuelo Basin (M-R, 1). The microalgae immobilization in calcium alginate beads protects the cells from the toxic effects of numerous substances and from extreme pH and temperatures, allowing better survival and greater efficiency in the production of biomass [2, 3]. However, cells trapped in the matrix are easy to be devoured by the fauna existent. Saladita Norte lagoon is part of M-R, this watercourse exhibits a wide range of contaminants levels along the year, mainly depending on the seasonal regime. At certain periods of the year, these levels usually exceed the limits established in international standards of water quality [4-6]. Similarly to that observed in other streams of M-R, several nitrogenated compounds, phosphorus, metals, and saprophytic and pathogenic bacteria are the main contaminants of Saladita Norte. In order to protect the alginate beads from the birds and fishes predation, a 3D-printed PLA (polylactic acid) device was designed. PLA is a biocompatible and biodegradable material that has been described as suitable for biotechnological applications. [7]. Bioprocesses carried out with this material must be checked for mechanical stability and optimal pore size to allow an effective bioremediation process. For this purpose, we used a stirredtank bioreactor supplied with a marine propeller and aeration during 6 days. Growth index and biomass production were compared between algae immobilized in alginate beads versus immobilized in alginate beads placed into a complex 3D printed PLA device. As previously observed, our native isolate of C. vulgaris could grow inside the alginate beads based on the consumption of several of the above-mentioned contaminants, such as phosphorus and nitrogenated ions [1]. The results obtained in control treatments with immobilized cells in alginate beads were: A- MS synthetic culture media supplemented with sucrose (3% w/v) and indolacetic acid (1 mg/L) as growth regulator [1] (mu=0.737, dt= 24 h) and B- as A- but growing in Saladita Norte water (mu=0.668, dt= 24 h). Also, treatments using 3D-device were: C- like B, but Chlorella cultures immobilized in alginate beads growing into a PLA3D scaffold coloured red (mu=0.341, dt= 2 d); D- like C, but coloured white (mu=0.206, dt= 3 d); and E- like C, but uncoloured (mu=0.342, dt= 2 d) were effective and successful to bioremediation in vitro. All cultures were kept at 24¡À2C, with a photoperiod of 16 h under PAR (above 400 mumol photon m-2 s-1). The data obtained were complemented with standardized cytotoxicity tests using Allium cepa and Lactuca sativa seeds. Germination rate and mitotic index of onion seeds and germination rate and length of lettuce seeds using polluted water or bioremediated water were compared. The results obtained demonstrate the potential of this technology to be used in integrated processes that seek removal of xenobiotics.
