In this research, have been investigated the effects of endophytic fungi from Neotyphidum genius that has mandatory symbiosis with tall fescue (Festuca arundinacea schreb) and drought stress on changes in the protein profile of the tall fescue species. This process requires changes in the gene and protein expression profiles. Since these proteins have not been reported for tall fescue species. ...

Despite its economic importance, not much information exists on growth and productivity of durum wheat in Iran and Isfahan. In order to evaluate growth, grain yield, and attributes in three durum wheat genotypes, Osta/Gata, Dipper-6, and PI40100, with five planting densities of 200, 275, 350, 425 and 500 seeds/m2, a four-replicate RCBD field study with a spilt-plot layout was carried out in win...

As salinity is becoming a major threat to the agricultural production in the arid and semi-arid parts of the world, exploring salt resistant genotypes for different crop plants, including chickpea (Cicer arietinum L.), is a very important task. Thus, in a 3-replicated completely randomized factorial pot experiment, six chickpea genotypes (i.e. Arman, Khorram-Abad, Nour-Abad, Hashem, Azad and IL...
