Modelling Ammonium Transporters in Arbuscular Mycorrhiza Symbiosis

The Stochastic Calculus of Wrapped Compartments (SCWC) is a recently proposed variant of the Stochastic Calculus of Looping Sequences (SCLS), a language for the representation and simulation of biological systems. In this work we apply SCWC to model a newly discovered ammonium transporter. This transporter is believed to play a fundamental role for plant mineral acquisition, which takes place i...

Sulfur transfer through an arbuscular mycorrhiza.

Despite the importance of sulfur (S) for plant nutrition, the role of the arbuscular mycorrhizal (AM) symbiosis in S uptake has received little attention. To address this issue, 35S-labeling experiments were performed on mycorrhizas of transformed carrot (Daucus carota) roots and Glomus intraradices grown monoxenically on bicompartmental petri dishes. The uptake and transfer of 35SO4(2-) by the...

Suppression of plant defence response by a mycorrhiza helper bacterium.

The aim of the present study was to determine whether the mycorrhiza helper bacterium Streptomyces sp. AcH 505 could serve as a biocontrol agent against Heterobasidion root and butt rot. Bacterial influence on mycelial growth of Heterobasidion sp. isolates, on the colonization of wood discs and Norway spruce (Picea abies) roots was determined. The effect of AcH 505 on plant photosynthesis, pero...

Tools Towards Managing Mycorrhiza for Sustainable Agriculture

The arbuscular mycorrhizal (AM) fungi, in concert with other soil dwelling microorganisms such as the so-called “plant growth promoting rhizobacteria”, play a pivotal role for natural soil fertility and stability, hence, for sustainable crop production. Appropriate management of the AM fungal community is crucial, especially in the tropics where the cultivated soils are notoriously fragile and ...
