Diversity of Arbuscular Mycorrhizal Fungi in Distinct Ecosystems of the North Caucasus, a Temperate Biodiversity Hotspot.

Background: Investigations that are focused on arbuscular mycorrhizal fungus (AMF) biodiversity is still limited. The analysis of the AMF taxa in the North Caucasus, a temperate biodiversity hotspot, used to be limited to the genus level. This study aimed to define the AMF biodiversity at the species level in the North Caucasus biotopes.

The Effects of Inoculation on Transcriptome of Leaves at Early Vegetative and Flowering Stages of Plant Development.

The study is aimed at revealing the effects of inoculation on the transcriptome of leaves at the early (second leaf formation) and later (flowering) stages of plant development. A pot experiment was conducted under conditions of low phosphorus (P) level in the substrate. plants were characterized by high mycorrhizal growth response and mycorrhization parameters.

The Role of Interaction with in the Determination of Root Metabolome at Early Stages of AM Symbiosis.

The nature of plant-fungi interaction at early stages of arbuscular mycorrhiza (AM) development is still a puzzling problem. To investigate the processes behind this interaction, we used the MlS-1 line that forms high-efficient AM symbiosis with . AM fungus actively colonizes the root system of the host plant and contributes to the formation of effective AM as characterized by a high mycorrhizal growth response (MGR) in the host plant.

Mycorrhiza-Induced Alterations in Metabolome of Leaves during Symbiosis Development.

The present study is aimed at disclosing metabolic profile alterations in the leaves of the MlS-1 line that result from high-efficiency arbuscular mycorrhiza (AM) symbiosis formed with under condition of a low phosphorus level in the substrate. A highly effective AM symbiosis was established in the period from the stooling to the shoot branching initiation stage (the efficiency in stem height exceeded 200%). Mycorrhization led to a more intensive accumulation of phosphates (glycerophosphoglycerol and inorganic phosphate) in leaves.

Metabolic alterations in pea leaves during arbuscular mycorrhiza development.

Arbuscular mycorrhiza (AM) is known to be a mutually beneficial plant-fungal symbiosis; however, the effect of mycorrhization is heavily dependent on multiple biotic and abiotic factors. Therefore, for the proper employment of such plant-fungal symbiotic systems in agriculture, a detailed understanding of the molecular basis of the plant developmental response to mycorrhization is needed. The aim of this work was to uncover the physiological and metabolic alterations in pea ( L.
