Powdery mildew, caused by Leveillula taurica, is a major fungal disease affecting greenhouse-grown pepper (Capsicum annuum). Powdery mildew resistance has a complex mode of inheritance. In the present study, we investigated a novel powdery mildew resistance locus, PMR1, using two mapping populations: 102 'VK515' F2:3 families (derived from a cross between resistant parental line 'VK515R' and su...

in the framework of a study on the powdery mildew fungi in iran, several infected plant specimens were collected from around the country during 2001-2009. based on the results of the study erysiphe quercicola on quercus sp. and e. malvae on malva sp., golovinomyces ambrosiae on helianthus spp., golovinomyces fischeri on senecio glaucus, are the newly reported for iranian mycobiota. in addition,...

Wall lizards of the genus Podarcis (Sauria, Lacertidae) comprise 17 currently recognized species in southern Europe, where they are the predominant reptile group. The taxonomy of Podarcis is complex and unstable. Based on DNA sequence data the species of Podarcis falls into four main groups that have substantial geographical conherence (western island group, southwestern group, Italian group an...

Some dialkyl alkylphosphonates and dialkyl phenylphosphonates were synthesized by the reactions between trialkyl phosphite and alkyl/aryl halide in the presence of benzene. The synthesized compounds were characterized by elemental analysis, thin layer chromatography (TLC), fourier –transform infrared, ( 1 H, 13 C) nuclear magnetic resonance (NMR) spectroscopic techniques. In vitro fungicidal ac...
