In a first experiment of soil contaminated with 137Cs, inoculation with a mixture of arbuscular mycorrhizae enhanced the uptake of 137Cs by leek under greenhouse conditions, while no effect on the uptake by ryegrass was observed. The mycorrhizal infection frequency in leek was independent of whether the 137Cs-contaminated soil was inoculated with mycorrhizal spores or not. The lack of mycorrhiz...

—Mycorrhizal fungi are ubiquitous components of terrestrial ecosystems that can influence plant performance, abundance and diversity. Patterns of allocation to specific mycorrhizal fungal structures could provide a useful context for understanding belowground dynamics in response to changing resources. Specifically, increased soil nutrient availability has been predicted to favor plants with lo...

Sodium stimulated ATPase activity in the nuclei of the meristematic cells, while potassium stimulated it in the mycorrhizae between root cap cells. The detection of these 2 mutually exclusive cation-stimulated ATPases, which both require magnesium-ATP in equivalents, which have a similar optimum pH of about 5.5, and which are located in entirely different parts of the root tip, suggests that pa...

Mycorrhizae are nearly ubiquitous symbioses formed between plants and fungi. Plants provide fungi with carbon captured through photosynthesis, while fungi provide plants with soil resources. Historically, research has focused on the effects of mycorrhizae on nutrient uptake and the fitness of individual plants. More recently, there has been a growing appreciation for the importance of mycorrhiz...

Rillig, M. C. 2004. Arbuscular mycorrhizae, glomalin, and soil aggregation. Can. J. Soil Sci. 84: 355–363. Arbuscular mycorrhizae are important factors of soil quality through their effects on host plant physiology, soil ecological interactions, and their contributions to maintaining soil structure. The symbiosis is faced with numerous challenges in agroecosystems; in order to inform sustainabl...

In a greenhouse trials, the effects of arbuscular mycorrhizae fungi (AMF) on growth and uptake of N, P, K and Pb by Eucalyptus rostrata L., grown with or without Phaseolus vulgaris, in lead (Pb) contaminated soil were investigated. Inoculation of the host plants with AMF, Glomus deserticola spores, significantly increased the dry weight, shoot length, total N, P and K as well as chlorophyll con...

Arbuscular mycorrhizal fungi [AMF] are soil fungi which form a mutualistic symbiosis with the roots of plants. A variety of benefits to the host have been ascribed to mycorrhizae, most often enhanced uptake of immobile nutrients from the soil, notably P. An understanding of the impacts of agronomic practices upon communities of these fungi would help to ensure an opportunity for the utilization...

Arbuscular mycorrhizae (AM) are benefi cial symbionts for plant growth. They are associated with higher plants by a symbiotic association, and benefi t plants in uptake of phosphorus nutrients, production of growth hormones, increase of proteins, lipids and sugars levels, helps in heavy metal binding, salinity tolerance, disease resistance, and even in the uptake of radionuclides. Mycorrhizal g...

Several types of orchids that are in great demand and cultivated by various groups Phalaenopsis sp. Dendrobium Mycorrhizae needed orchid plants to complete their life cycle. This is because mycorrhizae capable symbiosis with the root system host plant so plant's capacity absorb elements will increase. study aims determine extent which Ceratorhiza induction on amabilis discolour can suppress sym...

The ascomata and mycorrhizae of Tuber indicum s.l. were collected under the forest of broad-leaf species Populus yunnanensis and Quercus pannosa in the field respectively. The symbiotic relationships of both trees with T. indicum were examined and affirmed based on morphology and ITS-rDNA sequences. These two mycorrhizal combinations were successfully produced on artificially controlled substra...
