Microbial endophytes, which make one of the most important classes of soil microorganisms, induce genetic, physiological and ecological alterations in their host plant and thus increase its unit yield and enable its cultivation in saline or dry soils or in climates facing biotic and abiotic stresses. The endophyte fungus Piriformospora indica exhibits a high effect in plant growth and increased resistance against environmental tensions like drought and salinity, as well as against phytopathogens. The project is about ability of Piriformospora indica to improve growth and resistance of Hordeum vulgare L. on salt and drought stress. Also, identification of genes and mechanisms involved in this process is the other goal of this project. Former results showed that P. indica causes to increase aerial parts and root biomass of inoculated plants on stress situation compared with control plants. Findings of the project (that was done in ABRII-Iran) illustrated, beside of growth stimulation by P. indica, It has the effective role on improve the biomass in drought and salt stress. Proteome study presents inoculated plants in salt stress caused to overexpress of some proteins such as Ascorbate peroxidase و Glutathion- s- transferase that are responsible to reduce oxidative stress. We want to complete the result of proteome study and investigate the mechanisms involved in this tolerance. IPK institute is a big institute with facilities and equipments that is desirable for my work. Also, because some of these experiments like Microarray analysis have already been done in IPK institute, I want to join the project “Molecular mechanisms of salt tolerance in Barley” in IPK to complete the results.
