Arbuscular mycorrhizal fungi (AMF) are microscopic fungi that occur naturally in soil and form a symbiosis with plant roots. By colonizing the roots, the fungus increases plant growth by making soil essential elements like zinc and phosphorus more ac

Lipids are the major form of carbon storage in arbuscular-mycorrhizal fungi. We studied fatty acid synthesis by Glomus intraradices and Gigaspora rosea . [ 14 C]Acetate and [ 14 C]sucrose were incorporated into a synthetic culture medium to test fatt

Over the past few years, there has been a greater study and understanding of the application of phytoremediation to remediate contaminated soil. The enhancement of phytoaccumulation of heavy metals—zinc (Zn), cadmium (Cd), arsenic (As), and seleniu

Arbuscular mycorrhizal fungi (AMF) are microscopic fungi naturally occurring in soil that form a symbiosis with plant roots, producing a highly elaborated hyphal mycelium network in soil.In vitro lab experiments were conducted to determine whether ex

Abundant data on the effect of flavonoids on spore germination, hyphal growth and root colonization by AMF are available. Moreover, the flavonoid pattern in mycorrhizal roots changes, thus flavonoids have been suggested as arbuscular mycorrhizal sign

Four commercial composts were added to soil to study their effect on plant growth, total rhizosphere microflora, and incidence of plant growth-promoting rhizobacteria (PGPR) in the rhizosphere of tomato plants. Three of the compost treatments signifi

The effect of some plant growth-promoting rhizobacteria (PGPR) on greenhouse tomato fruit yields was determined during a spring and a fall production. The bacteria were inoculated into commercial peat-based substrates. In the spring crop, the bacteri

The polymerase chain reaction was used to amplify the spacer region located between the 16S and 23S ribosomal RNA genes of strains of Pseudomonas fluorescens and Pseudomonas putida isolated from peat bog, canola field, or arctic plants. Some of these

The antifungal activity of 644 bacterial isolates obtained from soil and from the rhizosphere of some leguminous plants was studied with one hyperparasite and six pathogenic fungi frequently associated with leguminous or gramineous plants. More than

Bacteria were consistently isolated from the root and crown xylem of symptomless field-grown alfalfa plants. Most of the plants tested contained more than one bacterial genus. Pseudomonas spp. accounted for 52% of the 387 isolates identified and the
