Translocation induced outgrowth of fungi in nutrient-free environments.

摘要: The study of alternatives to chemical methods nematode control in agriculture has received significant recent interest. One such method is biological using trapping fungi as Arthrobotrys superba. To understand how these can be implemented effective nematicides, it essential their outgrowth into soil from localized nutrient resources. In this paper, we use a mathematical model investigate the an environment essentially without available nutrients capable supporting net growth. By comparing solutions with experimental results, show that circumstances, continual mycelial expansion only obtained if internal metabolites are actively translocated through mycelium. Predictions made concerning maximal extension possible given quantity and testable functional relationship between two derived. Using modelling technique able map not biomass extent but also distribution at each stage. type environmental heterogeneity investigated here encountered by many species nature relevance for introduction specific or bioremediation purposes.
