Arbuscular mycorrhizal fungi (AMF) protect host plants against diverse biotic and abiotic stresses, and promote biodegradation of various contaminants. In this study effect of Glomus mosseae/Medicago sativa mycorrhiza on atrazine degradation was investigated. It was observed that the atrazine degradation rates with any addition level in mycorrhizal treatments were all significantly higher than those in non- mycorrhizal treatments. When atrazine was applied at 20 mg kg−1, the removal efficiency… 

Proteomic analysis of the response of Funnelifor mismosseae/Medicago sativa to atrazine stress

The findings of this study show that AMF played an important role in easing atrazine stress in plants and contributed toAtrazine remediation and further contributed to the understanding of the molecular mechanism associated with atrazin stresses and potential mycorrhizal contributions in M.sativa.

Genetic diversity of the symbiotic fungus: Rhizophagus irregularis and its effect on a plant host and a plant community

This thesis found that ecologists probably underestimated the functional diversity of AMF and unraveled important plant genes and fungal genes that could partly explain how the AM symbiosis could switch from one extreme to another along the symbiosis continuum, parasitic to mutualist.

Benefits of arbuscular mycorrhizal fungi in reducing organic contaminant residues in crops: Implications for cleaner agricultural production

Abstract Arbuscular mycorrhizal (AM) fungi (AMF) can not only improve soil and plant health, but also alter the accumulation of contaminants in plants. Here, the effects of AMF on the contents of

Transcriptome analysis of the differential effect of the NADPH oxidase gene RbohB in Phaseolus vulgaris roots following Rhizobium tropici and Rhizophagus irregularis inoculation

This research provides substantial insights into the genetic interaction networks in the early stages of rhizobia and AM symbioses with P. vulgaris, as well as the differential roles that RbohB plays in processes related to ROS scavenging, cell wall remodeling, and phytohormone homeostasis during nodulation and mycorrhization in this legume.

Stressed out symbiotes: hypotheses for the influence of abiotic stress on arbuscular mycorrhizal fungi

It is concluded that abiotic stress can have effects on AM fungi independent of the effects on the host plant, and should allow the maintenance of the plant-AM fungal mutualism in the face of changing climates.

Stressed out symbiotes

will change in composition in response to abiotic stress, which may mean the loss of important individual species. This could alter feedbacks to the plant community and beyond. AM fungi will adapt to

Biodegradation of atrazine and ligninolytic enzyme production by basidiomycete strains

This study revealed a high potential for atrazine biodegradation among tropical basidiomycete strains and highlighted less explored ligninolytic enzymes and cell-bound mechanisms that could enlighten key aspects of theAtrazine fungal metabolism and the role of the nitrogen in the process.

Germination of Seeds and Seedling Growth of Amaranthus retroflexus L. Following Sublethal Exposure of Parent Plants to Herbicides

The results suggest that although herbicides have a carry-over inhibition effect on the F1 generation of invasive plants, they may have a more serious carry- over effect on native plants and cause changes in weed species composition and weed diversity.



Bacterial degradation of Aroclor 1242 in the mycorrhizosphere soils of zucchini (Cucurbita pepo L.) inoculated with arbuscular mycorrhizal fungi

It is shown that AM fungi could enhance PCB dissipation by stimulating bph gene abundance and the growth of specific bacterial groups in bulk soil.

Arbuscular mycorrhizal fungi restore normal growth in a white poplar clone grown on heavy metal-contaminated soil, and this is associated with upregulation of foliar metallothionein and polyamine biosynthetic gene expression.

Mycorrhizal plants of P. alba clone AL35 exhibit increased capacity for stabilization of soil HMs, together with improved growth and enhanced stress tolerance, which may derive from the transcriptional upregulation of several stress-related genes, and the protective role of PAs.

Effect of Arbuscular Mycorrhizal (AM) Fungi on Atrazine Degradation in Soil Planted Sorghum

GM is an ideal AM fungus in remediation of Atrazine contaminated soil and AM inoculation could enhance urease activity but not significantly to catalase activity in soil.

Arbuscule-containing and non-colonized cortical cells of mycorrhizal roots undergo extensive and specific reprogramming during arbuscular mycorrhizal development.

To obtain insight into cell-specific reprogramming during AM symbiosis, comparative analyses of various cell types were performed using laser capture microdissection combined with microarray hybridization and the most prominent transcriptome changes were observed in non-arbuscule-containing cells of mycorrhizal roots.
