Mechanisms by which fungicides increase grain sink capacity and yield of spring barley when visible disease severity is low or absent

Fungicides are a central component of disease management programmes in many cereal production systems worldwide, but intensive use has led to problems with the evolution of resistance in pathogen populations, harmful effects on non-target organisms and residues in the food chain and environment. Better targeting of fungicide applications, according to the likely response of the crop, would help improve the sustainability of disease management, but decision making is hindered by our poor understanding of the mechanisms by which fungicides influence crop yield. This study investigated possible mechanisms responsible for yield increases following fungicide treatment of spring barley with little or no visible disease. Field experiments conducted over six site-years in the UK quantified the effects of the protectant fungicide chlorothalonil (Chl), and systemic fungicides prothioconazole (Pro) and pyraclostrobin (Pyr), applied on their own or in combination. The severity of visible disease in the absence of fungicide treatments was minimised by growing varieties with good disease resistance. Contrasting fungicide chemistries led to different effects on yield. There were two components to the yield increases. The first involved an increase (4.3-7.5 %) in grain number m(-2) and was elicited by Pro and Pyr, but not Chl. The second was a smaller increase (3.7-4.6%) in mean grain weight (MGW) and was elicited by each of the fungicides tested. The effect of the triazole (Pro) and strobilurin (Pyr) on grain number was not the result of the control of visible disease pre-anthesis or an increase in photosynthetically active radiation (PAR) interception. Nor was it the result of the control of asymptomatic pathogen infection or possibly leaf surface saprophytes, because Chl gave equivalent control without increasing grain number. Our results are consistent with the hypothesis that triazoles and strobilurins can increase grain sink capacity through direct physiological effects in the field. These apparent physiological effects differ from those reported for wheat as they occur pre-anthesis and are not associated with delayed leaf senescence and resulting increased PAR interception. Application of Pro + Pyr increased radiation use efficiency (RUE), estimated over the whole season, by around 10 % compared to untreated controls and 6 % compared to Chl treated crops. Evidence is presented to show that whilst the average yield response to Pro + Pyr in the absence of disease was around 3 %, the response varied widely between sites and years. Where effects on grain number do occur, they can be elicited in a range of varieties by a single application made at booting. We argue that benefiting from physiological effects of triazole and strobilurin fungicides on spring barley yield, through appropriate timing of application, is compatible with strategies to target and reduce fungicide use in this crop.

Very thermostable energetic materials based on a fused-triazole: 3,6-diamino-1H-[1,2,4]triazolo[4,3-b][1,2,4]triazole

3,6-Diamino-1H-[1,2,4]triazolo[4,3-b][1,2,4]triazole (1) and its energetic salts (2-9) were designed and synthesized based on a fused-triazole backbone with two C-amino groups as substituents. Their physicochemical and energetic properties were measured or calculated. Among them, compound 1 exhibits superior thermostability (T-d (onset): 261 degrees C), surpassing its analogues 3,7-diamino-7H-[1,2,4]triazolo[4,3-b][1,2,4]triazole (DATT, 219 degrees C) and 3,6,7-triamino-7H-[1,2,4]triazolo[4,3-b][1,2,4]triazole (TATOT, 245 degrees C). The differences in thermal stabilities were further investigated by determining the lowest bond dissociation energies (BDE) where a positive correlation between the stability of the molecules and the lowest BDE values is observed. The results show that 1 with the highest value for the lowest BDE has a superior thermostability in comparison to DATT and TATOT. The energetic salts (2-9) also exhibit remarkable thermal stabilities as well as low impact and friction sensitivities. The fused-triazole backbone 1H-[1,2,4]triazolo[4,3-b][1,2,4]triazole with two C-amino groups as substituents is shown to be a promising building block for construction of very thermally stable energetic materials.

Experimental and Theoretical Investigations Regarding the Thione-Thiol Tautomerism in 4-Benzyl-5-(thiophene-2-yl)-2,4-dihydro-3H-1,2,4-triazole-3-thione

The title compound was synthesized by ring-closure reaction of thiophene-2-carbohydrazide with benzyl isothiocyanate and characterized using spectroscopic methods (NMR and FT-IR). Quantum chemical calculations at the B3LYP/6-311++G(d,p) level were carried out to examine its molecular and spectroscopic properties, thione-thiol tautomerism, and proton transfer reaction. The structural and spectroscopic results were well consistent with the experimental data. The solvent effect on the proton transfer reaction was examined using three solvents (acetone, ethanol, and dimethyl sulfoxide) through the polarizable continuum model (PCM) approximation (direct solvent effect) and solvent-assisted mechanism. A high energy barrier was determined for the interconversion of the thione and thiol forms in both gas and solution phases. Even though the presence of solvent molecules significantly reduced the barrier to proton transfer, it was insufficient for the reaction to occur. The corresponding thermodynamic parameters and the energy difference between the HOMO and LUMO of the thione and thiol tautomers were calculated.

4.8 nm Concave {M-72} (M=Co, Ni, Fe) metal-organic polyhedra capped by 18 calixarenes

Three 4.8 nm isostructural {M-72} (M=Co-II for CIAC-128, Ni-II for CIAC-129, Fe-II for CIAC-130) metal-organic polyhedra (MOPs) are constructed by eighteen M-4-p-tert-butylthiacalix[4]arene (M-4-TC4A) units bridged via sixteen four-connected 5,5 ‘-(1H-1,2,4-triazole-3,5-diyl) diisophthalic acid (H(4)TADIPA) linkers. These MOPs are featured with a rarely reported concave coordination cage, which can be simplified as a squeezed double-decker hexagonal prism pressed from the top and bottom hexagonal faces. Furthermore, CIAC-128, CIAC-129 and CIAC-130 are the highest nuclearity discrete clusters of Co, Ni and Fe reported so far. CIAC-128 has higher separation selectivity of C3H8 than CH4 under ambient conditions, and also exhibits separation selectivity for C2H6/CH4, C2H2/CH4, and C2H4/CH4. In addition, CIAC-128 can provide the cavity for the confined synthesis of noble metal nanoclusters such as Pd nanoclusters and the resulting Pd@CIAC-128 hybrids show higher electrocatalytic activity than commercial Pt/C towards hydrogen evolution reaction (HER).

Identifying and explaining the regioselectivity of alkylation of 1,2,4-triazole-3-thiones using NMR, GIAO and DFT methods

The regioselectivity of the alkylation of four 1,2,4-triazole-3-thiones with eight different organic halides was determined by the comparison of experimentally observed NMR chemical shifts of the product molecules to those predicted by density functional theory (DFT) calculations via gage independent atomic orbital (GIAO) method. The combination of the employed reactants resulted in ten different model alkylated triazoles, seven of which are new and not previously described. The reaction was performed in neutral and alkaline medium with the observation that S-alkylation occurs selectively and with slightly lower yields under neutral conditions. Highest occupied molecular orbitals, electron localization function, electrophilic Fukui function, and different types of partial charges were considered as reactivity descriptors to reveal the observed regioselectivity and to explain the structure of synthesized products. In conclusion, the comparison of the chemical shifts of H-1 and C-13 NMR of the alpha-methylene group of the products with those calculated by incorporating the GIAO DFT-computed isotropic chemical shielding gives an approach for the correct and reliable determination of the site of alkylation as the S-atom of the synthesized S-alkylated 1,2,4-triazoles.

Synthesis of ring-opened derivatives of triazole-containing quinolinones and their antidepressant and anticonvulsant activities

Based on the potent antidepressant and anticonvulsant activities of the triazole-containing quinolinones reported in our previous work, a series of ring-opened derivatives of them were designed, synthesized in this work. Their antidepressant and anticonvulsant activities were screened using the forced swimming test (FST) and the maximal electroshock seizure test (MES), respectively. The results showed that compounds 4a, 5a, 6c-6e, 6g-6i, and 7 led to significant reductions in the accumulated immobility time in the FST at a dose of 50 mg/kg. Especially compound 7 exhibited higher levels of efficacy than the reference standard fluoxetine in the FST and the tail suspension test. The results of an open field test excluded the possibility of central nervous stimulation of 7, which further confirmed its antidepressant effect. Meanwhile, compounds 6a-6i and 7 showed different degrees of anticonvulsant activity in mice at the doses range from 300 to 30 mg/kg in the MES. Among them, compounds 6e and 7 displayed the ED50 of 38.5 and 32.7 mg/kg in the MES, and TD50 of 254.6 and 245.5 mg/kg, respectively. No one showed neurotoxicity at the dose of 100 mg/kg. The preliminary investigation forward to their mechanism indicated that regulation of GABAergic system might contribute to their anticonvulsive and anti-depressive action.

Dipeptides of S-Substituted Dehydrocysteine as Artzyme Building Blocks: Synthesis, Complexing Abilities and Antiproliferative Properties

Background: Dehydropeptides are analogs of peptides containing at least one conjugate double bond between alpha,beta-carbon atoms. Its presence provides unique structural properties and reaction centre for chemical modification. In this study, the series of new class of dipeptides containing S-substituted dehydrocysteine with variety of heterocyclic moieties was prepared. The compounds were designed as the building blocks for the construction of artificial metalloenzymes (artzymes). Therefore, the complexing properties of representative compounds were also evaluated. Furthermore, the acknowledged biological activity of natural dehydropeptides was the reason to extend the study for antiproliferative action of against several cancer cell lines. Methods: The synthetic strategy involves glycyl and phenylalanyl-(Z)-beta-bromodehydroalanine as a substrate in one pot addition/elimination reaction of thiols. After deprotection of N-terminal amino group the compounds with triazole ring were tested as complexones for copper(II) ions using potentiometric titration and spectroscopic techniques (UV-Vis, CD, EPR). Finally, the antiproliferative activity was evaluated by sulforhodamine B assay. Results and Conclusions: A simple and efficient procedure for preparation of dipeptides containing S-substituded dehydrocysteine was provided. The peptides containing triazole appeared to be strong complexones of copper(II) ions. Some of the peptides exhibited promising antiproliferative activities against number of cancer cell lines, including cell lines resistant to widely used anticancer agent.

Ameliorating effects of exogenous paclobutrazol and putrescine on mung bean [Vigna radiata (L.) Wilczek] under water deficit stress

Plant growth regulators play crucial roles in modulating plant response to environmental stresses. In this experiment, the effect of different doses of paclobutrazol (PBZ) and putrescine (Put), i.e., 0, 50, 100 and 150 mg/L on mung bean in two conditions of water deficit (WD) and well-watered (WW) was investigated. The seed yield decreased due to water deficit stress, while the PBZ and Put application alleviated the damage of drought stress through increasing proline and leaf chlorophyll content and improving membrane stability, and thus increased plant yield compared to untreated control plants. According to regression equations, the high PBZ levels (150 mg/L or more) and moderate levels of Put (about 90 mg/L) were determined as the optimal concentrations to maximise mung bean yield in WD conditions. In WW conditions, the mung bean responses to PBZ were inconsistent, whereas Put application positively affected some physiological traits and seed yield. In conclusion, the physiological attributes and, subsequently, the seed yield of drought-stressed mung bean plants could be improved by foliar application of PBZ and Put.

Coupling of N-tosylhydrazones with tetrazoles: synthesis of 2-beta-d-glycopyranosylmethyl-5-substituted-2H-tetrazole type glycomimetics

Coupling reactions of O-peracylated 2,6-anhydro-aldose tosylhydrazones (C-(beta-d-glycopyranosyl)formaldehyde tosylhydrazones) with tetrazoles were studied under metal-free conditions using thermic or microwave activation in the presence of different bases. The reactions proved highly regioselective and gave the corresponding, up-to-now unknown 2-beta-d-glycopyranosylmethyl-2H-tetrazoles in 7-67% yields. The method can be applied to get new types of disaccharide mimetics, 5-glycosyl-2-glycopyranosylmethyl-2H-tetrazoles, as well. Galectin binding studies with C-(beta-d-galactopyranosyl)formaldehyde tosylhydrazone and 2-(beta-d-galactopyranosylmethyl)-5-phenyl-2H-tetrazole revealed no significant inhibition of any of these lectins.
