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...
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...
متن کاملLocalized expression of arbuscular mycorrhiza-inducible ammonium transporters in soybean.
The majority of land plants acquire soil nutrients, such as phosphorus and nitrogen, not only through the root surface but also through arbuscular mycorrhizal (AM) fungi. Soybean is the most important leguminous crop in the world. We found 16 ammonium transporter genes in the soybean genome, five of which are AM inducible. Among them, promoter-reporter analysis indicated that the most abundantl...
متن کاملPlant 9-lox oxylipin metabolism in response to arbuscular mycorrhiza.
The establishment of an Arbuscular Mycorrhizal symbiotic interaction (MA) is a successful strategy to substantially promote plant growth, development and fitness. Numerous studies have supported the hypothesis that plant hormones play an important role in the recognition and establishment of symbiosis. Particular attention has been devoted to jasmonic acid (JA) and its derivates, the jasmonates...
متن کاملGibberellin–Abscisic Acid Balances during Arbuscular Mycorrhiza Formation in Tomato
Plant hormones have become appropriate candidates for driving functional plant mycorrhization programs, including the processes that regulate the formation of arbuscules in arbuscular mycorrhizal (AM) symbiosis. Here, we examine the role played by ABA/GA interactions regulating the formation of AM in tomato. We report differences in ABA and GA metabolism between control and mycorrhizal roots. A...
