Establishing a Symbiotic Interface between Cultured Ectomycorrhizal Fungi and Plants to Follow Fungal Phosphate Metabolism

Bio-Protocol, 2017
In ectomycorrhizal plants, the fungal cells colonize the roots of their host plant to create new organs called ectomycorrhizae. In these new organs, the fungal cells colonize the walls of the cortical cells, bathing in the same apoplasm as the plant ...

A Method for Radioactive Labelling of Hebeloma cylindrosporum to Study Plant-fungus Interactions

Bio-Protocol, 2017
In order to quantify P accumulation and P efflux in the ectomycorrhizal basidiomycete fungus Hebeloma cylindrosporum, we supplied 32P to mycelia previously grown in vitro in liquid medium.

Oscillatory decay of a two-component Bose-Einstein condensate

, 2001
We study the decay of a two-component Bose-Einstein condensate with negative effective interaction energy. With a decreasing atom number due to losses, the atom-atom interaction becomes less important and the system undergoes a transition from a bistable

Projective moduli space of semistable principal sheaves for a reductive group [PDF]

, 2000
Let X be a smooth projective complex variety, and let G be an algebraic reductive complex group. We define the notion of principal G-sheaf, that generalises the notion of principal G-bundle.
