Mycorrhizal spores were found to be closely associated with bacteria on their spore wall surface known as mycorrhiza associated bacteria (MAB) and its play a major role in the plant growth promotion by production of many known and unknown metabolites, nutrient solubilization and suppression of many soil borne pathogens in rhizosphere of crop plants. The present study was carried out to understa...

in order to investigate the effect of rhizobium bacteria, mycorrhiza fungi and foliar application of urea on qualitative and quantitative traits of soybean an experiment was conducted based on randomized complete block design with four replications. the experiment included six treatments as: control (c), rhizobium bacteria (r), rhizobium bacteria + mycorrhiza fungi (r+m), rhizobium bacteria + f...

Abscissic acid (ABA) determines mycorrhiza functionality and arbuscule development. In this study, we performed transcriptome analysis in response to different mycorrhization status according to the ABA content in the root to identify genes that may play a role in arbuscule functionality. Affymetrix Tomato GeneChip (approximately 10,000 probes) allowed us to detect and compare the transcription...

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...

The diversity of arbuscular mycorrhizal fungi (AMF) in 10 Oregon vineyards was assessed by examining spores in soil and amplifying mycorrhizal DNA from roots. Seventeen spore morphotypes were found in soil, including seven species in the Acaulosporaceae. Eighteen phylotypes were amplified from grape roots with AM1 and NS31 primers, and clones were dominated by Glomus spp. (> 99%). A few clones ...

Sci., 20: 849-855 Mycorrhizal fungi’s Glomus spp. and Trichoderma spp. are natural components of the healthy vineyard soils. They have the ability to improve nutrition and root resistance to attack by pathogens, and contribute positivel...

An investigation has been made about the vesicular arbuscular mycorrhizal fungi colonization in some medicinal plants Catharanthus roseus, C. pusillus, Wrightia tinctoria, Thevetia peruviana, Nerium indicum and Alstonia scholaris belongs to family Apocyanaceae were screened for the occurrence and association of VA mycorrhizal fungi. All the plants screened in the study harbored VA mycorrhizal f...

Arbuscular mycorrhiza is a mutualistic plant-fungus interaction that confers great advantages for plant growth. Arbuscular mycorrhizal (AM) fungi enter the host root and form symbiotic structures that facilitate nutrient supplies between the symbionts. The gibberellins (GAs) are phytohormones known to inhibit AM fungal infection. However, our transcriptome analysis and phytohormone quantificati...

Mycorrhizal symbiosis is a mutually beneficial association very commonly found among most vascular plants. Formation of mycorrhiza happens only between compatible partners and predicting this is often accomplished through a trial and error process. We investigated the possibility of using expression of symbiosis specific genes as markers to predict the formation of ectomycorrhiza. We used antib...
