The disease septoria leaf blotch of wheat, caused by fungal pathogen Septoria tritici, is of worldwide concern. The fungus exhibits a hemibiotrophic lifestyle, with a long symptomless, biotrophic phase followed by a sudden transition to necrotrophy associated with host necrosis. Little is known about the systematic interaction between fungal pathogenicity and host responses at specific growth s...

in iran, common bunt of wheat is one of the most important diseases of wheat and using resistant varieties is the best strategy against it. in order to find resistance sources against the disease for effective breeding programs, determining races of the pathogen is critical. in this study, spikes infected with common bunt of wheat were collected from different farms of khuzestan province in 200...

The wheat Tsn1 gene on chromosome 5B confers sensitivity to a host-selective toxin produced by the pathogens that cause tan spot and Stagonospora nodorum blotch (SNB) known as Ptr ToxA and SnToxA, respectively (hereafter referred to as ToxA). A compatible Tsn1-ToxA interaction is known to play a major role in conferring susceptibility of hexaploid (common) wheat to SNB. However, a recent study ...

Ficus religiosa L is one of the important medicinal plant widely used in pharmaceutical research. It is widely distributed in India and a religiously important host. In the present study, antibacterial activity of endophytic fungi isolated from Ficus religiosa was carried out. Organic extract of five dominant endophytic fungi viz Botryodiplodia theobromae, Colletotrichum gloeosporioides, Phomop...

ABSTRACT A major gene for resistance to wheat powdery mildew (Blumeria graminis f. sp. tritici = Erysiphe graminis f. sp. tritici) has been successfully transferred into hexaploid common wheat (Triticum aestivum, 2n = 6x = 42, AABBDD) from wild einkorn wheat (Triticum monococcum subsp. aegilopoides, 2n = 2x = 14, AA). NC96BGTA5 is a germ plasm line with the pedigree Saluda x 3/PI427662. The res...

During 2002-03 forty-four different barley growing regions in East Azarbaijanprovince of Iran were sampled for epiphytic fungi. Isolation of fungi was achieved using standard methods. As the result 374 hyphomycetous isolates were obtained that were placed in 22 genera and 49 species based on colony morphology and microscopic features (Table 1). Among these, Acremonium egyptiacum, A. sclerotigen...

Ochrobactrum tritici SCII24T is a highly As-resistant bacterium, with two previously described arsenic resistance operons, ars1 and ars2. Among a large number of genes, these operons contain the arsB and Acr3 genes that encode the arsenite efflux pumps responsible for arsenic resistance. Exploring the genome of O. tritici SCII24T, an additional putative operon (ars3) was identified and revealed...
