An investigation has been made about the vesicular arbuscular mycorrhizal fungi colonization in some medicinal plants Catharanthus roseus, C. pusillus, Wrightia tinctoria, Thevetia peruviana, Nerium indicum and Alstonia scholaris belongs to family Apocyanaceae were screened for the occurrence and association of VA mycorrhizal fungi. All the plants screened in the study harbored VA mycorrhizal f...

The halophytes Plantago maritima, Aster tripolium, Artemisia santonicum, Puccinellia limosa, Festuca pseudovina and Lepidium crassifolium from two different saline soils of the Hungarian steppe were examined for colonization by arbuscular mycorrhizal fungi (AMF). The salt aster (A. tripolium) and the sea plantain (P. maritima) were examined more thoroughly by recording root colonization paramet...

BACKGROUND AND AIMS Mycorrhizal associations are essential to the plant kingdom. The largest flowering plant family, the Orchidaceae, relies on mycorrhizal fungi for germination, growth and survival. Evidence suggests varying degrees of fungal-host specificity based on a single fungal isolate from a single plant. This paper shows for the first time the diversity of endophytes colonizing in a si...

The general objective of this study was to measure the mycorrhizal dependencies of Cupressus and Lavandula species, to assess the contribution of Lavandula species to the mycorrhizal soil infectivity (MSI) and to determine the main effects of the association between a Lavandula species (L. multifida) and Cupressus arizonica on the soil microbial activities, on the growth and the mycorrhizal sta...

The mycorrhizal colonisation of plants grown in unmanaged soils from two restoration sites with a fire history in Northern Portugal was evaluated from the perspective of supporting restoration programmes. To promote restoration of original tree stands, Quercus ilex L. and Pinus pinaster Ait. were used as target species on two sites, denoted Site 1 and 2 respectively. The aim of the study was to...

1. In England, the loss of lowland heathland, a habitat of global conservation importance, is primarily due to the invasion of birch and pine. This encroachment has been researched in depth from a plant perspective but little is known about the role of mycorrhizal fungi. In lowland heathlands the resident dwarf shrubs form ericoid mycorrhizas whereas invading trees form ectomycorrhizas. Therefo...

The conquest of the land by plants, c. 470 million years ago, was made possible by the arbuscular mycorrhizal symbiosis (Selosse et al., 2015). In fact, the evolution of that symbiosis was so successful that plant roots have to fit into an arbuscularmycorrhizal world. But that conclusion at the same time hides a paradox. If the arbuscular mycorrhizal symbiosis was so successful, which empty nic...

Mycoheterotrophic species have abandoned an autotrophic lifestyle and obtain carbon exclusively from mycorrhizal fungi. Although these species have evolved independently in many plant families, such events have occurred most often in the Orchidaceae, resulting in the highest concentration of these species in the tracheophytes. Studies of mycoheterotrophic species' mycobionts have generally reve...
