BACKGROUND Understanding the mechanisms underlying biological phenomena, such as evolutionarily conservative trait inheritance, is predicated on knowledge of the natural relationships among organisms. However, despite their enormous ecological significance, many of the ubiquitous soil inhabiting and plant symbiotic arbuscular mycorrhizal fungi (AMF, phylum Glomeromycota) are incorrectly classif...

influence of arbuscular mycorrhizal fungi (amf) (glomus etunicatum, g. intraradices and glomus versiforme) and external phosphorus supplement (8 and 35 mg p kg-1 soil) on leaf p, zn, cu and fe nutrition of 4-month-old tea(camellia sinensis) was studied in an glass house pot experiment. the highest leaf p concentration (up to 59.43% increase) was found in g. versiforme inoculated seedlings gro...

Excessive salt accumulation in soil is a major ecological and agronomical problem, especially in arid and semiarid areas. Excessive soil salinity affects the establishment, development and growth of plants, resulting in major losses of production. A pot experiment was set up to examine the effects of arbuscular mycorrhizal fungus (Glomus etunicatum and Glomus versiforme) and salinity on the gro...

Roots and rhizomes of Salvia miltiorrhiza (S. miltiorrhiza) are widely used for the treatment of cardiovascular diseases. Arbuscular mycorrhizal fungi (AMFs) have been shown to enhance plant growth and increase secondary metabolites concentration in many plant species. However, effects of AMFs on S. miltiorrhiza have not been explored. A pot culture was designed as one control (non-AMF) treatme...

In order to study the effects of drought stress and mycorrhiza fungi on establishment rate and some growth-morphological traits ofZiziphora clinopodoides, pot experiments were conducted as factorial design based on a completely randomized design at the research greenhouse of agricultural faculty, Ferdowsi University of Mashhad in 2014; pots were combined as four levels of drought stress includi...

Using a high-affinity phosphate transporter gene of Arabidopsis thaliana, PHT1, as a probe, three Arabidopsis homologs were isolated, named PHT4, PHT5 and PHT6, in addition to the previously isolated PHT2 and PHT3. The amino acid sequences deduced from the three nucleotides were 32-42% homologous with microbial phosphate transporters of Saccharomyces cerevisiae (PHO84), Neurospora crassa (PHO-5...

Abstract Salinity stress is a major threat that negatively affects plant growth and production in arid semi- regions. Application of biofertilizers could mitigate this stress. Accordingly, pot experiment was conducted on rapeseed grown under salinity (0, 5, 10, 15 dS m −1 ) while considering the following additives: (1) AMF (non-inoculated inoculated with Glomus versiforme (2) PGPR Micrococcus ...
