Pea (Pisum sativum) is an important grain legume crop whose cultivation in the Mediterranean basin and West Asia is severely constrained by infection by the weedy root parasite Orobanche crenata (crenate broomrape). Pea is a false host of other species such as O. minor, O. foetida and Phelipanche aegyptiaca. In the present experiments, we demonstrate that seed germination of the Orobanche and P...

Abstract Purpose Silicon (Si) accumulation by grasses alleviates diverse biotic and abiotic stresses. Despite this important functional role, we have limited understanding of how root microbial symbionts, such as arbuscular mycorrhizal (AM) fungi, affect Si uptake even less about supply AM fungal colonisation. Our objective was to determine the nature two–way interaction in model grass, Brachyp...

Arbuscular mycorrhizal (AM) fungi form mutualistic interactions with the majority of land plants, including some of the most important crop species. The fungus takes up nutrients from the soil, and transfers these nutrients to the mycorrhizal interface in the root, where these nutrients are exchanged against carbon from the host. AM fungi form extensive hyphal networks in the soil and connect w...

Restoration quality of native prairie can be improved by reintroducing key organisms from the plant microbiome such as arbuscular mycorrhizal (AM) fungi. Here, we assess whether positive effects a inoculation observed during first growing season remained at end fourth season. In 2016, an experiment was initiated that assessed response restored tallgrass to density gradient fungi ranging 0 8,192...

Koch Departments of Environmental Sciences, Biological Sciences, and the Merriam-Powell Center for Environmental Research, Northern Arizona University, Flagstaff, AZ 86001-5694, USA *Correspondence: E-mail: [email protected] Abstract We examined plant community responses to interactions between arbuscular mycorrhizal (AM) fungi and availabili...

An investigation was carried out to study the AM fungal association in Sida cardifolia from different parts of Karnataka. AM colonization in the roots, spore load and Phosphatase activity in the root zone soil collected from different parts of Karnataka were determined. AM root colonization was more in the roots of Sida cardifolia collected from Kolar and least in case of root samples collected...

Most higher plants have the ability to form arbuscular endomycorrhiza (AM); a symbiotic association of the plant root with fungi belonging to the order of Glomales. These fungi grow towards the inner cortical cells of the root where they differentiate into highly branched structures, the arbuscules (Figure 1). In AM symbiosis, the fungus also forms hyphae outside the plant and these provide a c...

appropriate management of soil phosphorus (p) fertility in highly calcareous soils of iran as around the world should rely upon sound knowledge about the phosphorus reserve and its bioavailability. despite numerous reports on the positive effects of vesicular arbuscular mycorrhizae (vam) fungi on phosphorus uptake which is associated to ectomycorrhiza as a branch of two major branches of group ...

Arbuscular mycorrhizal fungi (AMFs) play an important role in soil improvement, leading to the enhanced growth and yield of host plants. The diversity, abundance, richness AMFs were evaluated eight coffee plantations (Coffea arabica L.) with different erosion degrees. results indicated that 26 morphotypes scattered across four genera recovered included five species. Funneliformis species most d...
