Previous studies have shown that the blast fungus, Magnaporthe oryzae, may experience nitrogen starvation during infection of its plant host (rice,Oryza sativa). Here, we studied the expression of seven genes encoding cysteine-rich proteins with N-terminal signal peptides during nitrogen limitation and throughout the infection process. Some genes were upregulated to a greater extent in weak pat...

Septic arthritis is the most rapidly destructive joint disease, but its early diagnosis remains challenging; delayed or inadequate treatment, even by expert physicians, can lead to irreversible joint destruction. Between 25% and 50% of patients develop irreversible loss of joint function, which is especially concerning in elderly patients. To understand the factors influencing the outcome of se...

Genetic analysis of host specificity in the rice blast fungus (Magnaporthe grisea) identified a single gene, PWL2 (for Pathogenicity toward Weeping Lovegrass), that exerts a major effect on the ability of this fungus to infect weeping lovegrass (Eragrostis curvula). The allele of the PWL2 gene conferring nonpathogenicity was genetically unstable, with the frequent appearance of spontaneous path...

Soil-borne diseases caused by pathogenic microorganisms are one of the main factors responsible for the decline in crop yields in farmlands. Pathogenic Fusarium oxysporum causes serious damage to various crops, and, thus, a feasible diagnostic method for soil-borne diseases is required. We herein examined a simple method to evaluate the suppressiveness of soil microorganisms against a pathogen ...

The lysin motif (LysM) containing proteins can bind chitin and are ubiquitous in various organisms including fungi. In plant pathogenic fungi, a few LysM proteins have been characterized as effectors to suppress chitin-induced immunity in plant hosts and therefore contribute to fungal virulence. The effector mechanism is still questioned in fungus-animal interactions. In this study, we found th...

in order to study the combined and separate effects of phosphorus fertilizer, phosphate-solubilizing bacteria and mycorrhizal fungus on adjusting and reducing the loss of yield resulting from drought stress during the stage of growth of grain corn (sc704) an experiment was performed in aboureihan campus of the university of tehran, iran, during 2007-2008. the experiment was conducted as split p...

Fungal agents, especially yeasts, are resident in digestive system as microflora and they can invade the mucosal tract in animals with predisposing factors. The prevalence of the resident fungal flora in the digestive tract of healthy broilers and layers during April to September 2008 was investigated. The samples were taken from the preventriculus, jejunum and cecum contents of 120 birds and c...

The most prevalent form of chronic dermatophytoses causing pathogenic fungus in humans is Trichophyton rubrum. Keratinocytes, the main epidermal cells, are crucial local immune interactions because they represent first line defense against microbial assaults, skin In response to varied stimuli, keratinocytes express a wide range receptors and create host peptides, cytokines, chemokines, this im...
