In the last times, focus on plant research has increased all over the world. Euphorbia tirucalli L., a plant known popularly as Aveloz, and originally used in Africa, has been drawing attention for its use in the United States and Latin America, both for use as an ornamental plant and as a medicinal plant. E. tirucalli L. is a member of the family Euphorbiaceae and contains many diterpenoids an...

In this study, the relation of plasma levels of lathosterol (an indicator of whole body cholesterol synthesis) and plant sterols (indicator of cholesterol absorption) with age, sex, weight, height, plasma lipids, and lipoproteins, and with apolipoprotein (apo) E phenotype, was investigated in a group of 160 nuclear families consisting of twins living with their parents. Lathosterol was higher i...

In addition to the important role of abscisic acid (ABA) in abiotic stress signalling, basal and high ABA levels appear to have a negative effect on disease resistance. Using the ABA-deficient sitiens tomato (Solanum lycopersicum) mutant and different application methods of exogenous ABA, we demonstrated the influence of this plant hormone on disease progression of Erwinia chrysanthemi. This ne...

Involvement of an oxidative burst, usually related to incompatible plant/pathogen interactions leading to hypersensitive reactions, was investigated with Erwinia amylovora, the causal agent of fire blight of Maloideae subfamily of Rosaceae, in interaction with pear (Pyrus communis; compatible situation) and tobacco (Nicotiana tabacum; incompatible situation). As expected, this necrogenic bacter...

simulation optimization is a scientific tool that is widely used to design and optimize comminution circuits in mineral processing plants. In this research, first of all, in order to  determine the suitable d80 for cicuit hydrocyclone underflow, the requiremed parameters of simulator (residence time distribution, breakage function, selection function and Plitt’s model calibration) were determin...

boraginaceae family is known as a medicinal plant classified in dicotyledons.  it is originated from asia (middle east). the aim of this study was to evaluate ingredient between 4 species of boraginaceae family based on physiological & phytochemical traits as well as seed fatty acid contents.  4 species (e. russicum, e. italicum, e. amoenum, and b. officinalis ) were evaluated carefully. all se...

The significant increase in foodborne outbreaks caused by contaminated fresh produce, such as alfalfa sprouts, lettuce, melons, tomatoes and spinach, during the last 30 years stimulated investigation of the mechanisms of persistence of human pathogens on plants. Emerging evidence suggests that Salmonella enterica and Escherichia coli, which cause the vast majority of fresh produce outbreaks, ar...

Vegetation composition and reproduction of vascular plants were studied in relation to seven spatial structures: Betula pendula, Pinus sylvestris, Juniperus communis, Rosa dumalis, dung pats, grazing rejects and grazed patches. Th e study was performed in 14 unfertilized semi-natural pastures, with diff erent grazing intensities, in southcentral Sweden. Vegetation height diff ered between sites...

Some microbial symbionts of plants are maternally inherited and thus functionally increase genetic and phenotypic variation within plant populations. This variation, coupled with that of the host plant and environment, may alter abundances, diversity, and trophic structure of associated plant and animal communities. Fungal endophytes in the genus Neotyphodium are vertically transmitted, asexual...
