The present paper analyses the community structure of ectomycorrhiza (ECM) and arbuscular mycorrhiza (AM) fungi associated with seven different poplar clone types growing in a patch system on soil from four different former land use types, originating from spruce forest, poplar stand, grassland and cornfield. We determined the extent to which ECM and AM play a role on the studied factors (genot...

The arbuscular mycorrhiza (AM) brings together the roots of over 80% of land plant species and fungi of the phylum Glomeromycota and greatly benefits plants through improved uptake of mineral nutrients. AM fungi can take up both nitrate and ammonium from the soil and transfer nitrogen (N) to host roots in nutritionally substantial quantities. The current model of N handling in the AM symbiosis ...

Studies on Rhizobium-legume symbiosis show that trehalose content in nodules under drought stress correlates positively with an increase in plant tolerance to this stress. Fewer reports describe trehalose accumulation in mycorrhiza where, in contrast with rhizobia, there is no flux of carbohydrates from the microsymbiont to the plant. However, the trehalose dynamics in the Mycorrhiza-Rhizobium-...

Most of the farmers who grow cactus pear (Opuntia albicarpa) use manure as a fertilizer. This practice increases problems pests. The endomycorrhiza (Glomus intraradices) is almost unknown to farmers. Therefore, objective this research was study effect application with organic matter (OM) and inoculation in pear.

two ectomycorrhizal fungi, Pisolithus tinctorius (Pers.) Coker and Couch and Paxillus involutus (Batsch) Fr., was studied in vitro. Spermidine was the main polyamine in the mycelium of both fungi. Paxillus involutus also produced large amounts of the diamine putrescine, whereas Pisolithus tinctorius contained traces of the diamine cadaverine and released into the culture medium an unknown compo...

The production of maize has significant nutrient needs, notably for nitrogen. Considering the negative impact chemical fertilizer on ecosystem, alternative supply nutrients that is easily accessible and environmentally benign must be sourced. This study looked into effects inoculating mycorrhizae diazotrophs growth biomass output maize. treatments included three (3) levels mycorrhiza (without m...

The response of pea (Pisum sativum cv. Avola) to arbuscular micorrizal fungi (AM) species Glomus mosseae and Glomus intraradices and Rhizobium leguminosarum bv. Viciae, strain D293 regarding growth, nodulation and nitrogen fixing activity was studied. Pea plants (Pisum sativum cv. Avola) were grown in a glasshouse until flowering stage (35 days) in 4 kg plastic pots using leached cinnamonic for...

The tolerance of lettuce plants (Lactuca sativa L. cv. Romana) to drought stress differed with the arbuscular-mycorrhizal fungal isolate with which the plants were associated. Seven fungal species belonging to the genus Glomus were studied for their ability to enhance the drought tolerance of lettuce plants. These fungi had different traits that affected the drought resistance of host plants. T...

Arbuscular mycorrhiza fungi (AMF), obligate symbionts, are important in the majority of cultivated plant species colonizing roots and supporting growth adverse climatic conditions. However, abundance quality mycorrhizal colonization is affected by land-use types, cropping systems climate change. On other hand, rhizospheric mycorrhizae present soils can be isolated for enhancing performance. One...
