abstract in low-input cropping systems, the natural roles of microorganisms in maintaining soil fertility may be more important than conventional system. in order to investigate the effects of plant growth promoting fungi on improvement of growth and development in soybean (cv: jk) an experiment was conducted at the research farm of sari agricultural sciences and natural resources university du...

Abstract In order to study the effect of different soil amended and biological fertilizers on accumulation nitrogen phosphorous in wheat grain some physiological morphological characteristics wheat, this experiment was performed as a split factorial arranged randomized block design with 32 treatment three replication for 2 years. The treatments included mycorrhiza inoculation main factor (witho...

Symbiosis involves responses that maintain the plant host and symbiotic partner's genetic program; yet these cues are far from elucidated. Here we describe the effects of lumichrome, a flavin identified from Rhizobium spp., applied to lotus (Lotus japonicus) and tomato (Solanum lycopersicum). Combined transcriptional and metabolite analyses suggest that both species shared common pathways that ...

Two experiments were conducted over 2 years in commercial potato fields in Shropshire, UK, to evaluate the compatibility of the nematicide aldicarb with commercial inocula of arbuscular mycorrhizal fungi (AMF) in the control of the potato cyst nematode Globodera pallida. The AMF used were Vaminoc (mixed-AMF inoculum), Glomus intraradices (BioRize BB-E) and G. mosseae (isolate BEG 12). In the ab...

The diversity of arbuscular mycorrhizal fungi (AMF) in 10 Oregon vineyards was assessed by examining spores in soil and amplifying mycorrhizal DNA from roots. Seventeen spore morphotypes were found in soil, including seven species in the Acaulosporaceae. Eighteen phylotypes were amplified from grape roots with AM1 and NS31 primers, and clones were dominated by Glomus spp. (> 99%). A few clones ...

Pharmaceuticals and personal care products may enter the terrestrial environment through the amendment of agricultural soils with manure or biosolids with potential impacts on beneficial soil microbe populations. The beneficial symbiotic relationship between most plant species and arbuscular mycorrhizal fungi is a primary determinant of plant health and soil fertility. As such, there is increas...

Drought is one of the most critical environmental stresses that reduce agricultural production. This study aimed to examine effects individual and simultaneous inoculation Rhizophagus intraradices, Serendipita indica, Pseudomonas fluorescens on physical properties soil growth parameters single cross 704 maize under three levels drought stress (80%, 50%, 25% available water). It was found intrar...

BACKGROUND As one of the most widely used organophosphate insecticides in vegetable production, phoxim (C(12)H(15)N(2)O(3)PS) is often found as residues in crops and soils and thus poses a potential threat to public health and environment. Arbuscular mycorrhizal (AM) fungi may make a contribution to the decrease of organophosphate residues in crops and/or the degradation in soils, but such effe...

Members of the Brassicaceae are generally believed to be non-mycorrhizal. Pennycress (Thlaspi) species of this family from diverse locations in Slovenia, Austria, Italy and Germany were examined for their colonisation by arbuscular mycorrhizal fungi (AMF). Meadow species (T. praecox, T. caerulescens and T. montanum) were sparsely but distinctly colonised, as indicated by the occurrence of intra...
