The first DNA sequences obtained from arbuscular endomycorrhizal fungi are reported. They were obtained by directly sequencing overlapping amplified fragments of the nuclear genes coding for the small subunit rRNA. These sequences were used to develop a polymerase chain reaction primer (VANS1) that enables the specific amplification of a portion of the vesicular-arbuscular endomycorrhizal fungu...

Th ere have been several reports of symbionts in the roots of plants that live in aquatic environments. Arbuscular mycorrhizal fungi (AMF) are the most common microsymbionts and possibly recolonized the aquatic environment together with plants; however, their functions and the extent of their benefi ts are unclear. Furthermore, the presence of other groups of fungi, such as dark septate fungi (...

Inoculation with arbuscular mycorrhizal (AM) fungi has often promoted increased growth of plants but very little work has been done in the tropics to evaluate the effects of inoculation on the establishment and development of seedlings in forests. Desmoncus orthacanthos Martius is a scandent palm present both in early and late succession, and consequently can be used in restoration processes. A...

Fungi interact directly with trees as biotrophs (obtaining nutrients from living cells/tissues) either parasites or mutualistic mycorrhizas, and as necrotrophs (obtaining nutrition from cells/tissues that they kill). Mycorrhizas are crucial to the health of the vast majority of plants in nature, supplying them with water and mineral nutrients, and protecting against root pathogens. Fungi affect...

In this study seven plant species were collected from the forest of Arasbaran located in the northwest of Iran. Sampling was conducted in May and August and roots were used for calculating vesicular arbuscular mycorrhizal colonization percentage during the same period. Fine roots were separated, washed and put in FAA solution as a fixative. Through the time, root colonization of all plant speci...

The response of plants to arbuscular mycorrhizal fungi involves a temporal and spatial activation of different defence mechanisms. The activation and regulation of these defences have been proposed to play a role in the maintenance of the mutualistic status of the association, however, how these defences affect the functioning and development of arbuscular mycorrhiza remains unclear. A number o...

Ericaceae are a group of plants with biotechnological and commercial importance. These establish symbiotic associations wide mycorrhizal fungi. National global studies have focused on two them: arbuscular endomycorrhizae ectomycorrhizae. The most recent type mycorrhiza recorded is the cavendishioid ectendomycorrhizae. one least-studied understood mycorrhizae, along monotropoid arbutoid mycorrhi...
