Phytophthora species are considered as the major cause of several plant diseases resulting in huge yield losses in agricultural crops. Despite years of effort to develop Phytophthora resistance varieties, there is no reports of a resistant cucumber variety. In this study, the effect of concomitant application of potassium phosphite (KPhi) and chitosan on some physiological and molecular respons...

abstractbackground and objectives: the cultivated tobacco (nicotiana tabacum) is a tropical and annual plant, consisting of a number of species or hybrids belonging to the solanaceae family. bio-chemical reaction to viral infection is different for various plants .one of the most important defensive mechanisms of the host plant against pathogen agents, is biochemical defense and their related c...

To study the effect of chemical and biological fertilizers on growth and essential oil content of lavender (Lavandula angustifolia Mill.), the present work was conducted in 2012-2013 at the experimental field of Alborz Research Station of the Research Institute of Forests and Rangelands, Karaj, Iran. The experiment was conducted in factorial in the form of a randomized complete block design wit...

some research indicates that n2 fixation in soybean cannot provide adequate nitrogen for proper yield. therefore, the effect of nitrogen and bradyrhizobium japonicum bacteria on some agronomic characteristics and quality of soybean cultivars was examined based on split plot in a randomized complete blocks design with three replications in 2012 at kerman township. treatments including control (w...

seed inoculation by means of mycorrhizal fungi can alleviate the side-effects of fungicides on production of crops and their yields. an experiment was conducted in 2009 at the research field of islamic azad university, faculty of agriculture, mahdasht, karaj. in order to investigate the influence of different kinds of fungicides on colonization of mycorrhizal species and on grain yield in soybe...

From the past late blight is one of the most dreaded diseases of potato worldwide. In this study, microarray-based gene expression was analysed in a late blight resistant Indian potato cultivar Kufri Girdhari upon Phytophthora infestans infection. A comprehensive transcriptional analysis was performed using cDNA microarrays, containing 70,083 ESTs (expressed sequence tag libraries) from plant l...
