The factors that influence a plant’s ability to invade are not well understood. Many mechanisms are involved and the relative importance of different mechanisms depends on the specific invasion. Here we consider one factor—mycorrhizal symbioses. These symbioses are ubiquitous interactions involving the plants and soil fungi of most terrestrial ecosystems. We develop a conceptual framework for c...

introduction: herbicides, despite of their control of weeds, have the potential to affect sensitive crops in rotation and also beneficial non-targeted soil microbes including vesicular arbuscular mycorrhiza (vam) fungi (6). am fungi can increase the growth of crops through increasing uptake of phosphorus and insoluble micronutrients, and indirectly by improving soil quality parameters (30). how...

recent studies in scientific education as well as foreign and second language instruction suggest that thinking has rarely been an integral part of education and training in classroom. some scholars decried the lack of emphasis on thinking in the institutes and schools. they noted that memorization and drills were rewarded,while inquiry, reflection, and consideration of alternatives were frowne...

T he availability of reduced nitrogen and phosphate are limiting factors in the productivity of many terrestrial ecosystems. The majority of land plants increase phosphate nutrition by developing intimate associations with beneficial mycorrhizal fungi. Legumes are unusual among plants because they also establish a symbiosis with nitrogen-fixing bacteria, known generally as rhizobia. A high leve...

The increasing demand for medicinal plants has amplified the importance of the development of effective methods for enhancing the cultivation of these plants. The association of arbuscular mycorrhizal (AM) fungi with medicinal plants has been found to alter the level of secondary metabolites by affecting the plant metabolism. Lemon balm (Melissa officinalis L.), is an important medicinal plant ...

if the precise implementation of the principle of proportion and:balance between the violation and the penalty as well as the other dimensions could be considered as a stick yard for the imptementation of justice any lack of preciseness in carrying out such principle would not indeed be much too far from injustice . naturally ,if it would be imagined that the objective of balance between...

Mycorrhizal fungi channel significant amounts of recently fixed plant carbon (C) through the soil, affecting a number of soil processes including the composition and activity of microbial communities and soil organic matter (SOM) mineralization. Some of the mycorrhizal fungi (particularly those establishing ecto-, ericoid and orchid mycorrhizas) can directly mineralize SOM, although often they ...

Arbuscular Mycorrhizal Fungi (AMF) are a group of obligate biotrophs, to the extent that they must develop a close symbiotic association with the roots of a living host plant in order to grow and complete their life cycle [1]. The term “mycorrhiza” literally derives from the Greek mykes and rhiza, meaning fungus and root, respectively. AMF can symbiotically interact with almost all the plants t...

Drought stress is one of the most important environmental stresses affecting plant growth, yield and crop production around the world. It is believed that arbuscular mycorrhizal fungi are used for protecting plants against drought damage.Vesicular-arbuscular mycorrhizal fungi have been used in recent years to cope with water stress in many plants. In this study, the relationship between water d...
