During AM formation, modulation of plant defense responses occurs, potentially through cross-talk between SA and JA dependent signalling pathways (Pozo and Azcon-Aguilar 2007). This modulation may also impact plant responses to potential enemies by priming the tissues for a more efficient activation of defense mechanisms in addition to conferring a balance between the AMF and the host. Although there is not much known in AM about cross talk of JA and SA, investigation on the reactions of plants...

Development and Morphology of Extraradical Arbuscular Mycorrhiza Hyphal Networks

Mycorrhizal Fungi Agar Plate

Though a network of AM fungal hyphae is present in almost every terrestrial ecosystem, knowledge about its morphology and development is still scarce. A major reason for this may lie in methodological difficulties to extract and observe AM mycelia from the soil. Blending, wet sieving, and decanting of soil samples is a common method to extract fungal hyphae (Hanssen et al. 1974 Li et al. 1991a Jakobsen et al. 1992), but particularly on soils rich in organic or porous particles, may not yield...

Effects of AM Fungal Mycelia on Chemical and Physical Mycorrhizosphere Properties and Implications for Mineral Element

The soil in the vicinity of a plant root is altered in its chemical, physical or biological properties by the activities of the root. Plant nutrient uptake may lead to decreased concentrations of some elements, while others may accumulate when their massflow towards the root surface exceeds plant uptake Marschner 1995 . Substances released by plant roots into the soil might feed certain soil bacteria, or mobilize mineral elements from sparingly soluble pools Walker et al. 2003 . The soil under...
