In the Yangtze Valley of China, Pyrus pyrifolia is known by the name sand pear and often suffers abnormal, early leaf senescence and premature defoliation, which causes serious yield loss and poor fruit quality. In this study, the relationship of Alternaria alternata with abnormally senesced leaves (ASLs) was analyzed by physiological and molecular method. Using data from the P. pyrifolia cultivars ‘Huanghua’ and ‘Suisho’, we found that A. alternata inoculation caused early leaf senescence. Restricted foliar nutrient redistributions were observed in ASLs, such as nitrogen (N) and phosphorus (P). Higher abscisic acid (ABA) levels were induced in the tissues of the leaf mesophyll, veins and stalks of ASLs, and higher concentrations of indole-3-acetic acid (IAA) and H2O2 were induced in the tissues of leaf mesophylls and veins of ASLs, while an opposite trend was observed in the tissues of leaf veins. Quantitative real-time PCR (qRT-PCR) consistently demonstrated that ASLs upregulated the expression of ABA biosynthesis genes (e.g., PyNCED3, PyZEP and PyAAO3), and the catabolism gene (PyABA8 ‘ OH), whereas PyBG and PyDXS showed opposite trends. Based on the leaf senescence database (LSD) 3.0, 42 senescence-associated genes (SAGs) that induced differential expression by A. alternata inoculations were enriched for P. pyrifolia cv. ‘Hongfeng’, which has high susceptibility to A. alternata and readily exhibits early leaf senescence. These results showed that A. alternata infection is one of major factors for abnormal leaf senescence and ABA signaling involved in this pathogenic process.

In a article, author is Chen, Long, introduce new discover of the category.

A BrOnsted acid catalysed regiodivergent phosphorylation of 2-indolylmethanols with diarylphosphine oxides has been established, which provides a brand-new strategy for accessing highly functionalized phosphorus-containing indoles with structural diversity. Under the catalysis of HOTsH2O, 2-indolylmethanols undergo regioselective benzylic phosphorylation at room temperature to afford benzylic site phosphorylated indoles in good to high yields (29 examples, up to 98% yield), while C3-phosphorylated indoles are obtained in the presence of HOTf under heating conditions (16 examples, up to 83% yield). Preliminary mechanistic studies suggest that C3-phosphorylated indoles are possibly obtained partially from direct C3-phosphorylation and dominantly from a tandem benzylic phosphorylation/[1,3]-P migration/isomerization sequence from 2-indolylmethanols. Furthermore, the acidity of the BrOnsted acid and the reaction temperature play a vital role in the [1,3]-P migration of benzylic phosphorylated indoles to form C3-phosphorylated indoles. This protocol serves as a good example for regioselective benzylic functionalization of 2-indolylmethanols.

Biosurfactants are environment compatible surface-active biomolecules with multifunctional properties which can be utilized in various industries. In this study a biosurfactant producing novel plant growth promoting isolate Pseudomonas guariconensis LE3 from the rhizosphere of Lycopersicon esculentum is presented as biostimulant and biocontrol agent. Biosurfactant extracted from culture was characterized to be mixture of various mono- and di-rhamnolipids with antagonistic activity against Macrophomina phaseolina, causal agent of charcoal rot in diverse crops. Fourier transform infrared spectroscopy (FTIR) and proton nuclear magnetic resonance (H-1 NMR) analysis confirmed the rhamnolipid nature of biosurfactant. PCR analysis established the presence of genes involved in synthesis of antibiotics diacetylphloroglucinol, phenazine 1-carboxylic acid and pyocyanin, and lytic enzymes chitinase and endoglucanase suggesting biocontrol potential of the isolate. Plant growth promoting activities shown by LE3 were phosphate solubilization and production of siderophores, indole acetic acid (IAA), ammonia and 1-aminocyclopropane-1-carboxylate deaminase (ACCD). To assemble all the characteristics of LE3 various bioformuations were developed. Amendment of biosurfactant in bioformulation of LE3 cells improved the shelf life. Biosurfactant amended formulation of LE3 cells was most effective in biocontrol of charcoal rot disease of sunflower and growth promotion in field conditions. The root adhered soil mass of plantlets inoculated with LE3 plus biosurfactant was significantly higher over control. Biosurfactant amended formulation of LE3 cells caused maximum yield enhancement (80.80%) and biocontrol activity (75.45%), indicating that addition of biosurfactant improves the plant-bacterial interaction and soil properties leading to better control of disease and overall improvement of plant health and yield.

A Cu(OAc)(2)-promoted oxidative cross-dehydrogenative coupling reaction of a-acylmethyl malonates with indole derivatives was developed. In the case of indoles, the regioselective coupling products were formed through a sequential dehydrogenation-addition-dehydrogenation process. When a second nucleophilic center was located in the 2-position of indoles, further successive nucleophilic cyclization occurred to give polycyclic indole derivatives. The Cu(OAc)(2) was proved to act as not only an oxidant but also a catalyst.

Different priming methods were developed to improve seed germination and the early growth of seedlings. This study aimed to examine the combined effect of bacterial inoculation and static magnetic field on white mustard (Sinapis alba L.) germination. A plant growth-promoting bacterial strain Bacillus amyloliquefaciens D5 ARV was used for biopriming. The static magnetic field of 90 mT was applied for 5 and 15 min. Analyses of abscisic acid, chlorophyll, anthocyanins, flavonoids content, nitrogen balance index, and bacterial indole-3-acetic acid were used to explain observed effects. Bacterial inoculation improved seed germination, whereas exposure to 90 mT for 15 min suppressed germination. Such an unfavorable effect was neutralized when the treatment with the static magnetic field was combined with bacterial inoculation. The highest germination percentage was a result of synergistic action of B. amyloliquefaciens D5 ARV and 15 min long exposure to 90 mT, which induced an increase of 53.20% in the number of germinated seeds. The static magnetic field induced the increase of bacterial indole-3-acetic acid production threefold times. Biomagnetic priming caused a metabolic shift from primary to secondary metabolism in the white mustard seedlings. An adequate combination of biological priming and static magnetic field treatment can be successfully used in old seed revitalization and germination improvements.

Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view. Like 51298-62-5, Name is L-NAME Hydrochloride. In a document, author is Wu, Liangqiang, introducing its new discovery. Formula: https://www.ambeed.com/products/51298-62-5.html.

By connecting 1,8-naphthalimide and indole sulfonate, a ratio fluorescent probe capable of differential detection of hydrogen sulfite and hypochlorite was synthesized for the first time. It was able to achieve the qualitative detection of HSO3- and ClO- with high sensitivity and selectivity, respectively. It provides a multi-purpose probe and is based on different emission channels without mutual interference. The probe has the advantages of larger Stokes shift (ClO-: 115 nm, HSO3-: 88 nm), longer lambda(em) (ClO-: 515 nm, HSO3-: 548 nm) and better water solubility (DMF/PBS = 1:99, v/v). In addition, the probe is a ratio fluorescence probe, which can detect fluorescence intensity with two different emission waves. It provides internal self-calibration, reduces interference from the background and increases detection accuracy. In vitro cytotoxicity and imaging experiments show that the probe can effectively perform the detection of exogenous HSO3- and ClO- in cells. It can also achieve the detection of HSO3- and ClO- in the plasma environment. Because the probe can detect endogenous ClO-, it also has a good prospect for biological application in identifying tumor cells.

One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, such as the rate of change in the concentration of reactants or products with time. 209216-23-9, Name is Entecavir Monohydrate, formurla is C12H17N5O4. In a document, author is Lin, Li Ping, introducing its new discovery. Recommanded Product: 209216-23-9.

Two new and rare bioactive indoles named dalesindoloids A (1) and B (3), along with 3-(1H-indole-3ylmethyl)-2-oxindole (2), were characterized from the indole-3-carbinol (I3C)-exposed culture of Daldinia eschscholzii. The absolute configuration of 2 was determined by quantum chemical calculations of the electronic circular dichroism (ECD) spectrum. Dalesindoloids A and B were cytotoxic against the leukemia HL-60 cell line with the IC50 values of 1.0 and 7.4 mol/L, respectively, with the former being inhibitory on Staphylococcus aureus (MIC: 9.1 mol/L). The simultaneous characterization of the alkaloids from the I3C-exposed fungal culture highlighted that the 2,3-epoxyindoline motif can be transformed into both lactam and indolin-3-one moieties. This is the first-time description of the 2,3-epoxyindoline chemical versatility and Wagner-Meerwein rearrangement (WMR) reaction in the microbial culture.
