Volume 1 • Issue 5 • 1000e117 J Plant Biochem Physiol ISSN: 2329-9029 JPBP, an open access journal The versatility of fungi allows them to associate with plants in many ways. When interacting with a live organism, a fungus will invade its plant host and manipulate its metabolisms either detrimentally or beneficially, depending on whether the fungus is a pathogen or a symbiote. Many crop disease...

the effects of arbuscular mycorrhizal (am) fungi on growth and phosphorus (p) inflow into two species of clover plant with different root morphology were studied. the experiment was arranged as a randomized complete block design consisting of a 2×3×3 factorial combination of two clover species (trifolium alexandrinum l. and trifolium pratense l.), three mycorrhiza states (without mycorrhiza, gl...

This study characterizes the molecular and phylogenetic identity of fungi involved in arbuscular mycorrhizal (AM) associations in extant Huperzia and Lycopodium (Lycopodiaceae). Huperzia and Lycopodium are characterized by a life cycle with long-lived autotrophic sporophytes and long-lived mycoheterotrophic (obtain all organic carbon from fungal symbionts) gametophytes. 18S ribosomal DNA was is...

The present paper analyses the community structure of ectomycorrhiza (ECM) and arbuscular mycorrhiza (AM) fungi associated with seven different poplar clone types growing in a patch system on soil from four different former land use types, originating from spruce forest, poplar stand, grassland and cornfield. We determined the extent to which ECM and AM play a role on the studied factors (genot...

Arbuscular mycorrhizal (AM) fungi colonize roots improving plant water status and tolerance to drought. However, it is not clear whether the presence of AM would affect the photosynthesis and antioxidant gene-enzymes response, which help to alleviate drought stress of the host plant. Here, pot experiments were performed to investigate the effects of Rhizophagus irregularis, an AM fungus, on the...

Arbuscular mycorrhiza (AM) fungi (Glomeromycota) form symbiosis with and deliver nutrients via the roots of most angiosperms. AM fungal hyphae are taken up by living root epidermal cells, a program which relies on a set of plant common symbiosis genes (CSGs). Plant root epidermal cells are also infected by the plant growth-promoting fungus Piriformospora indica (Basidiomycota), raising the ques...

During arbuscular mycorrhizal (AM) colonization, a focal accumulation of organelles occurs in root epidermal cells, prior to fungal penetration, beneath adhering hyphopodia. This is followed by the appearance of the prepenetration apparatus (PPA), a transcellular column of cytoplasm connected to the nucleus and rich in cytoskeleton and secretory endomembranes. This apparatus appears to be respo...

The effects of two Bacillus strains (Bacillus pumillus and B. licheniformis) on Medicago sativa plants were determined in single or dual inoculation with three arbuscular-mycorrhizal (AM) fungi and compared to P-fertilization. Shoot and root plant biomass, values of thymidine and leucine incorporation as well as ergosterol and chitin in rhizosphere soil were evaluated to estimate metabolic acti...

Plant biostimulants such as arbuscular mycorrhizal (AM) fungi and humic substances (HS) can be used as an appropriate alternative to chemical fertilizers, as regards to environmental problems of chemicals. The effects of Funneliformis mosseae as an AM fungus, HS (foliar spray and topdressing application), and chemical fertilizer (NK), separately or interacting, on biochemical responses in Menth...

Effect of constant and diurnally fluctuating temperatures on arbuscular mycorrhizal (AM) fungi [Glomus etunicatum (GE) and Gigaspora margarita (GM)] infection and the promotion of infected seedling growth through asparagus-AM fungus symbiosis were investigated. 1. At constant temperatures, spore germination rate became maximum at 25 •Ž in GE, and at 25•Ž and 30•Ž in GM. Hyphal growth was enhanc...
