Nitric oxide (NO) plays a key role in plant diseases resistance. Here we have first time demonstrated that begomovirus infection in susceptible H. cannabinus plants, results in elevated NO and reactive nitrogen species production during early infection stage not only in infected leaf but also in root and shoot. Production of NO was further confirmed by oxyhemoglobin assay. Furthermore, we used Phenyl alanine ammonia lyase as marker of pathogenesis related enzyme. In addition evidence for protein tyrosine nitration during the early stage of viral infection clearly showed the involvement of nitrosative stress.Key words: nitric oxide, mesta yellow vein mosaic virus, protein nitration 相似文献

The preparation of boronated triaryl and tetraaryl phosphonium salts of the type [PPh3CH2R]Br [R is 4-boronophenyl (1), 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-yl)phenyl (2), 3-boronophenyl (3), 3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-yl)phenyl (4), 2-boronophenyl (5), 2-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-yl)phenyl (6), and closo-1,2-carboran-1-yl (7)] is described. These compounds were prepared by the reaction of triphenylphosphine with benzylic bromides or 1-bromomethyl-closo-1,2-carborane in acetonitrile solution at 85 °C. The zwitterionic nido-7,8-carborane derivative PPh3CH2C2B9H11 (8) was prepared by treatment of 7 with cesium fluoride in refluxing ethanol. All compounds were fully characterized by multinuclear (1H, 11B, 13C, and 31P) 1D- and 2D-NMR spectroscopy, electrospray ionization mass spectrometry, and elemental analysis, and single-crystal X-ray
structures were determined for compounds 1, 3, 7, and 8. The cytotoxicities and boron uptake of selected derivatives were investigated in vitro using human glioblastoma (T98G) and
canine kidney tubule (MDCK II) cells. The zwitterionic species 8 was found to be the least cytotoxic agent while also delivering the greatest amount of boron to the T98G cells, peaking at
9.15 ± 2.65 μg B/mg protein. 相似文献

Cellular morphology, macromolecular composition, (DNA, RNA and Protein content) marker enzyme activities for neurons [neuron specific enolase (NSE)] and astrocytes [glutamine synthetase (GS)] and plasma membrane protein profiles in the bulk isolated neurons and astrocytes from control and ethanol treated rats were studied. One month aged Wistar rats were given ethanol as sole drinking fluid for 10 weeks. Scanning electron microscopy revealed a characteristic cell surface smoothening in astrocytes due to ethanol treatment. DNA levels were unaltered, while RNA and Protein contents were decreased in astrocytes and neurons. Further,3H-leucine incorporation into proteins was decreased in neurons and astrocytes derived from ethanol treated rats indicating reduced protein synthesis in neurons and astrocytes. GS activity was affected severely suggesting impairment in astrocytic functions. Plasma membrane protein composition was analyzed by 2-D electrophoresis. The analysis indicated several protein defects in the plasma membranes of neurons and astrocytes, which might be involved in membrane disorder during ethanol challenge.125I-Wheat Germ agglutinin binding studies showed three prominent proteins (160, 116 and 97 kDa) in astrocyte membrane fraction suggesting the possible involvement of N-terminal glycoproteins in altered astrocyte morphology during ethanol ingestion. Impairment in the astrocyte cell functions, protein changes in plasma membrane and cellular morphology studies suggest that astrocytes may be more vulnerable than neurons for ethanol effects. 相似文献

Chalcogenide semiconductor quantum dots are emerging as promising nanomaterials due to their size tunable optoelectronic properties. The commercial synthesis and their subsequent integration for practical uses have, however, been contorted largely due to the toxicity and cost issues associated with the present chemical synthesis protocols. Accordingly, there is an immediate need to develop alternative environment‐friendly synthesis procedures. Microbial factories hold immense potential to achieve this objective. Over the past few years, bacteria, fungi and yeasts have been experimented with as eco‐friendly and cost‐effective tools for the biosynthesis of semiconductor quantum dots. This review provides a detailed overview about the production of chalcogen‐based semiconductor quantum particles using the inherent microbial machinery. 相似文献

Summary Water potential () measurements of Atriplex canescens at the base of the Red Desert near Tipton in Wyoming, revealed a range between-15.5 to-45.1 bars. Minimum values coincided with the lowest air and soil temperatures, maximum with the greatest atmospheric evaporative demand. Change in exceeded 12 bars h-1 during periods of rapidly moving storm systems. Changes in appeared to be independent of plant size, age, sex, and the spatial location of plants. Chemical analyses revealed that xylem sap was up to three times more concentrated at high than at low . It was observed that the flow rate of sap was greater at lower than at higher and that the increase in water movement accounted for the dilution of the baseline concentration of sap solutes. Together, Ca, Mg, K and Na contributed 58% of the mean osmolality of the xylem sap; the dominant ions, however, were K and Cl. We suggest that the ability of the species to respond rapidly to changing atmospheric conditions affords it a distinct advantage in a harsh environment. 相似文献
