In this study, it was aimed to determine the antagonistic effect between and isolated from eggplant roots some root bacteria conditions. 24 were soil samples taken rhizosphere regions of infected non-infected plants in different production areas 22 them evaluated as candidate biocontrol agents. According results research, 13 out effective against, 14 9 against 40% 100%. The most 22B (100%) 11B ...

The present study was carried out to determine parasitic infection of sheep with gastrointestinal helminthes in a slaughterhouse in Fereidoonkenar city, Iran. A total number of 50 sheep were examined from April to September 2008. Nematodes were removed from abomasums, small and large intestines, and kept in A.F.A. solution (alcohol, formaldeyde, acetic acid, distilled water, and glycerine) for ...

Two different DNA fragments, one of 2.9 kilobases and the other of 5.1 kilobases, were cloned from Phytophthora citrophthora and showed no homology with DNA from plants and other related fungi. These DNA probes hybridized with DNA from 12 different P. citrophthora isolates obtained from a variety of hosts but did not hybridize with DNA from 6 P. citrophthora isolates obtained from cacao. Southe...

RAC/ROP proteins (ρ-related GTPases of plants) are plant-specific small G proteins that function as molecular switches within elementary signal transduction pathways, including the regulation of reactive oxygen species (ROS) generation during early microbial infection via the activation of NADPH oxidase homologs of plants termed RBOH (for respiratory burst oxidase homolog). We investigated the ...

Infected urachal cysts are a rare clinical manifestation in adults. We present the case of a female patient with an infected urachal cyst, discuss the embryology, clinical presentation, diagnostics and the therapeutic procedure and make a comparison with the literature.

Transcripts for two genes expressed early in alfalfa nodule development (MsENOD40 and MsENOD2) are found in mycorrhizal roots, but not in noncolonized roots or in roots infected with the fungal pathogen Rhizoctonia solani. These same two early nodulin genes are expressed in uninoculated roots upon application of the cytokinin 6-benzylaminopurine. Correlated with the expression of the two early ...

rhizomania (root madness) is caused by beet necrotic yellow vein virus (bnyvv). this disease was first reported fromitalyin 1959 and fromfars,iranin 1996. during the recent years, it has been increasingly developing across the country so that most beet production areas such as khorasan, fars, west azarbaijan,isfahanandkermanshahare now more or less affected by the disease. typically, the taproo...

The influences of Gaeumannomyces graminis var. tritici (which causes take-all of wheat), Rhizoctonia solani AG-8 (which causes rhizoctonia root rot of wheat), Pythium irregulare, P. aristosporum, and P. ultimum var. sporangiiferum (which cause pythium root rot of wheat) on the population dynamics of Pseudomonas fluorescens 2-79 and Q72a-80 (bicontrol strains active against take-all and pythium ...

The corn cyst nematode Heterodera zeae [1], was first detected on the roots of maize collected from Rajasthan, India [1-3]. The pest has subsequently been reported to be present in Pakistan [35], Thailand [2,6], Egypt [7], Greece [8]. Portugal [9] and Virginia and Maryland in the USA [2,10,11] Heterodera zeae is restricted to warmer tropical and sub-tropical areas. And its distribution can be s...

Picoa species are hypogeous desert truffles, which can be found in semi-arid ranges of North Africa, West Asian, South of Europe and Middle East, including Iran (Moreno et al. 2000, Jamali & Banihashemi 2012, 2013). Picoa species form symbiosis mainly on roots of annual and perennial herbaceous plants of the Helianthemum, including H. ledifolium and H. salicifolium var. salicifolium (Jamali & B...
