Roots of intact olive seedlings, axenically cultured, were alternatively placed in contact with Rhizophagus irregularis (mycorrhizal) or Verticillim dahliae (pathogenic) fungi. MeJA treatments were also included. In vivo redox activities in the apoplast of the intact roots (anion superoxide generation, superoxide dismutase and peroxidase activities) were measured. All our results showed that ap...

The aim of the study was to investigate species diversity AM fungi in different parts North Caucasus, biodiversity hotspot, center world’s biological diversity. Samples were taken from 5 locations (stationary trial plots, STPs) ecosystems and at various altitudes. Identification performed using sequencing for ITS1 ITS2 regions, amplified with universal primers, Illumina MiSeq employed. 19 gener...

Plant and fungal partners in arbuscular mycorrhizal symbiosis trade mineral nutrients for carbon, with the outcome of this relationship for plant growth and nutrition being highly context-dependent and changing with the availability of resources as well as with the specific requirements of the different partners. Here we studied how the model legume Medicago truncatula, inoculated or not with a...

Maize (Zea mays) is the most widely grown crop species in the world and a classical model organism for plant research. The completion of a high-quality reference genome sequence and the advent of high-throughput sequencing have greatly empowered re-sequencing studies in maize. In this study, plants of maize inbred line B73 descended from two different sets of seed material grown for several gen...

1. Accumulating evidence indicates that plant resistance against aboveground herbivores can be affected by the presence of arbuscular mycorrhizal fungi (AMF) in association with the host plant. Little is known, however, about how AMF composition can influence herbivore choice to feed on a particular plant. 2. Unravelling the preference–performance hypothesis in a multitrophic context is needed ...

Nicotianamine is an essential molecule for Fe homeostasis in plants, its primary precursor is the S-containing compound methionine, and it is biosynthesized by the enzyme family of nicotianamine synthases (NASs). In maize, a graminaceous plant that follows Strategy II for Fe uptake, ZmNAS genes can be subgrouped into two classes, according to their roles and tissue specific expression profiles....

Horizontal gene transfer (HGT) is an important mechanism in the evolution of many living organisms particularly in Prokaryotes where genes are frequently dispersed between taxa. Although, HGT has been reported in Eukaryotes, its accumulative effect and its frequency has been questioned. Arbuscular mycorrhizal fungi (AMF) are an early diverged fungal lineage belonging to phylum Glomeromycota, wh...

Arbuscular mycorrhizal fungi (AMF) are widespread endosymbionts in terrestrial ecosystems and their exudates have important effects on soil properties. A greenhouse experiment was conducted with six AMF treatments including four exotic species inoculums (Funneliformis mosseae ,Claroideoglomus claroideum  and Rhizophagus irregularis and a mixed isolate of three species), one mixed native AMF spe...

   مایکوریزا می‌تواند به عنوان ابزاری کارآمد در جهت افزایش بهره­وری مصرف عناصر غذایی در راستای کشاورزی پایدار استفاده ‌شود. این آزمایش با هدف بررسی برهم‌کنش سطوح فسفر و قارچ مایکوریزا بر شاخص­های رشدی و تولید ریزغده و جذب عناصر غذایی گیاهچه­های سیب­زمینی در گلخانه، به صورت فاکتوریل بر پایه طرح کاملا تصادفی در سه تکرار در سال 1393 در مرکز تحقیقات کشاورزی و منابع طبیعی استان همدان اجرا گردید. عام...
