Volatile organic compounds (VOCs) have well-documented roles in plant-plant communication and directing animal behavior. In this study, we examine the less understood roles of VOCs in plant-fungal relationships. Phylogenetically and ecologically diverse strains of Fusarium oxysporum, a fungal species complex that often resides in the rhizosphere of assorted plants, produce volatile compounds th...

some possible effects of exogenous application of salicylic acid (sa) and bacillus subtilis on infection potential of root and stem rot disease and on induction of resistance against this pathogen were investigated in laboratory and as well under greenhouse conditions. in vitro, the effectiveness of sa concentrations (2-8mm) on growth of b. subtilis was observed as negative, while sa applicatio...

Background: Epigenetic modifications, such as methylation can occur in multiple myeloma. SMG1is an important gene involved in cell growth which defect in methylation of its promoter leads to reduction of cell apoptosis and uncontrolled proliferation. In this study, we identified the methylation status of the SMG1 gene promoter in patients with multiple myeloma. Methods: Methylation status of S...

We recently isolated the AtBI-1 (Arabidopsis Bax Inhibitor-1) gene, the expression of which suppressed Bax-induced cell death in yeast. To determine whether the same is true in the plant system, transgenic Arabidopsis plants overexpressing Bax protein under a dexamethasone (DEX)-inducible promoter were generated. On DEX treatment, such transgenic plants exhibited marked cell death at the whole-...

Abstract A field study was carried out to determine the influence of foliage applied plant growth promoter and retardant in improving soil sulphur fertilizer use efficiency cotton during two consecutive summers 2014 2015. Experimental trial comprised three different sources (ammonium sulphate, potassium sulphate elemental sulphur) foliar spray including tap water taken as control. Among treatme...

Sclerotinia sclerotiorum is a phytopathogenic fungus which causes serious yield losses in canola. A pathogen inducible-promoter can facilitate the production of Sclerotinia-resistant transgenic canola plants. Inthis study, the “gain of function approach” was adopted for the construction of a pathogen-inducible promoter.The synthetic promoter technique was used, which involved the in...
