Abstract Microbes are sources of a diverse array of phytotoxic compounds. These compounds are generally structurally different from commercial herbicides, targeting different molecular sites of action within the plant. These novel structures and sites can be excellent leads for the discovery and development of safer synthetic herbicides. Microbial phytotoxins are often more environmentally benign than synthetic herbicides. Examples of phytotoxins from fungi (AAL‐toxin, cornexistin, cyperin, and tentoxin) with novel structures and sites of action are discussed. AAL‐toxin is toxic to a wide variety of weeds at very low dose rates. AAL‐toxin and many of its analogues kill plants by inhibiting a ceramide synthase‐like enzyme, causing rapid accumulation of free sphingoid bases that disrupt membranes. Cornexistin appears to be metabolically cnverted to an inhibitor of certain aspartate amino transferase isoenzymes. Its activity can be reversed by feeding aspartate and glutamate or with tricarboxylic acid cycle intermediates. Its activity is much like that of (aminooxy)acetate. Cyperin is a diphenylether phytotoxin that inhibits protoporphyrinogen oxidase, but does not kill plants by this mechanism. It appears to have other effects on porphyrin metabolism. Tentoxin is toxic by two mechanisms. It disrupts chloroplast development by inhibiting the processing of a nuclear‐coded plastid protein, and it also inhibits photophosphorylation by acting as an energy transfer inhibitor of coupling factor 1 ATPase. Other examples of phytotoxins from microbes with promise as herbicides will be mentioned. 相似文献

AbstractThe impact of sub-lethal exposure to deltamethrin on the expression of hepcidin, ferroportin and transferrin genes in Wistar rats was studied. A dosage of 30?mg/kg per day for five days was found to modify the hepcidin-ferroportin axis that primarily governs iron homeostasis. Significant variations in erythrocyte, leukocyte, lymphocyte, platelet and monocyte counts, as well as the reduced serum protein profile, suggested anemia. The results collectively demonstrated the novel finding of deltamethrin’s disruptive effect on iron homeostasis. 相似文献

This study describes optimization of headspace solid phase microextraction followed by gas chromatography equipped with a flame ionization detector for toluene at trace level in spiked urine. The parameters affecting the extraction and gas chromatographic determination of analytes were studied: extraction time and temperature; desorption time and temperature; addition of NaCl; and pH, volume and agitation of the sample. Optimized headspace extraction was carried out at 30 °C for 6 min in the presence of 0.2 g-m-1of NaCl in the sample solution. Also, sample volume and sample pH were optimized at 5 ml and 7 (neutral pH), respectively. Desorption of the analytes was carried out at 250 °C for 60 s. The optimized procedure was validated with 3 different pools of spiked urine; it showed good reproducibility over 6 consecutive days and 6 within-day experiments. The study also determined the accuracy, linearity and detection limits of this method. 相似文献

The research examines the street's physical characteristics that are influenced by the culture in the city of Mashhad, Iran as a case study. It is evident that new developments in the traditional street have mostly eroded the cultural value of the urban environment. The techniques used for data collection include literature review, in-depth interview, questionnaire and field observation. The research outcome indicated, firstly, the street's physical characteristics which were influenced by culture and shaped the street form and function as a corridor to the Holy Shrine, a significant Iranian landmark. It is indicated that culture is a way of life influencing the physical appearance, activities and behavioural aspects that these are important to support human needs, therefore to create a sense of place. Secondly, culture, in line with the physical characteristics, would enhance the uniqueness of the street and its cultural value to support distinctiveness of the street environment. The third finding proves that cultural aspects have a significant role in activating public life and increasing the attractiveness of the street. 相似文献

The purpose of this study was to investigate the relationship between organizational and personal (individual) factors with the prevalence of musculoskeletal disorders (MSDs) in office workers of the Iranian Gas Transmission Company. The participants rated two questionnaires – the standardized Nordic Musculoskeletal Questionnaire to measure the prevalence of MSDs, and the Veterans Healthcare Administration All Employee Survey questionnaire (2004 version) – to measure psychosocial, organizational and individual aspects of job satisfaction and workplace climate. The highest prevalence of MSDs was found in the lower back (49.7%) and neck (49.0%) regions. Results of the logistic regression models showed that some psychosocial and organizational factors and also some individual factors were associated with prevalence of MSDs (p < 0.05).These ?ndings illustrate the need to consider all elements of the work system as a whole in future studies and in organizational planning. 相似文献
