Control of arbuscular mycorrhiza development by nutrient signals
Inorganic phosphate (Pi), the main form of phosphorus used by plants, is one of the most important limiting factors for plant growth. In the soil soluble Pi that is readily available for uptake, occurs at very low concentrations (Schachtman et al., 1998). One adaptation of plants to low Pi availability is the symbiosis with arbuscular mycorrhiza fungi (AMF) of the phylum Glomeromycota. The fung...
متن کاملArbuscular mycorrhiza-specific signaling in rice transcends the common symbiosis signaling pathway.
Knowledge about signaling in arbuscular mycorrhizal (AM) symbioses is currently restricted to the common symbiosis (SYM) signaling pathway discovered in legumes. This pathway includes calcium as a second messenger and regulates both AM and rhizobial symbioses. Both monocotyledons and dicotyledons form symbiotic associations with AM fungi, and although they differ markedly in the organization of...
متن کاملSignal transduction and signaling networks
Cellular signaling can be complex and dynamic. In the past several decades, it has become clear that many signal transduction pathways are not simple one-way transmissions of upstream stimuli, but are mediated through extremely complicated networks. Our next challenge is to move beyond the static biochemical description of networks into developing a functional quantitative understanding of thei...
متن کاملModelling 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...
متن کاملSulfur 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...
