چکیده مقاله:
To obtain a better understanding of the mycorrhizas as an elicitor, and precursor feeding effects on the protein content and TIAs biosynthesis in Catharanthus roseus L., foliar application of four concentrations of tryptophan (0, 150, 250 and 350 mg/l) on some growth parameters and chemical compositions of mycorrhizal plants were investigated. The results revealed that the total protein content in the shoots and roots was higher respectively in G. etunicatum and G. versiforme mycorrhizal plants treated by 350 mg/l tryptophan, and this enhancement was significant at 5% statistical level. The evaluation of SDS-PAGE obtained results showed that the application of mycorrhizas and tryptophan led to significant accumulation of a 50-55 kDa M.W protein in the shoots and roots which probably could be attributed to TDC enzyme. From this observation we could suggest that the treatment of both mycorrhizas and tryptophan may be resulted in high expression of TDC enzyme.

Caspian Coastal Forests: Arbuscular Mycorrhizal Fungi and Understory Vegetation
Moist and temperate Caspian forests are associated with a diversity of soil types and topography. Although, natural history and ecological attributes of the Caspian vegetation is well-documented, little is known about mycorrhizae of the Caspian (Hyrcanian) flora. Samples of herbaceous plant species were collected from 4 pre-determined altitudes (-13 upto about 1500m above sea level, appro...
متن کاملArbuscular Mycorrhizal Fungi and Alien Plant Species
The invasion success of alien plant species depends, amongst other things, on their functional traits [4] and the susceptibility of ecosystems. There is now increasing interest in including biotic interactions particularly mutualistic associations [5], into frameworks assessing alien plant invasions, as they help bridge the invisibility and invasiveness features. The great majority of terrestri...

The potential of three arbuscular mycorrhizal fungi (AMF) - Glomus mosseae, G. fasciculatum and G. intraradices- to enhance the production of essential oil and plant growth parameter was investigated in sweet basil (Ocimum basilicum). The AMF inoculation significantly increased plant height, fresh and dry matter yield, oil content and oil yield as compared to non-inoculated basil plants. Essent...

Cold stress is an important limiting factor for cereal production. Barley is a host species for arbuscular mycorrhizal fungi (AMF) with a high genetic diversity in response to cold stress. In order to explore the mechanisms for the ameliorative effect of AMF under cold stress, an experiment was undertaken using completely randomized block design with three factors including temperature treatme...

The effects of three Arbuscular Mycorrhizal Fungi (AMF) species (Glomus versiforme, Claroideoglomus etunicatum and Rhizophagus intraradices) were studied on the growth parameters and nutrient uptake of three apple rootstocks (M.9, M.7 and MM.106). The soil medium contained a high level of calcium carbonate (38.65%). The results showed that AMF inoculation could increase almost all growth parame...
