What does the published scientific research say about Rhizopogon fulvigleba?

Eight PubMed records are indexed for Rhizopogon fulvigleba in a plant-input context. The cited abstracts cover Rhizopogon species as ectomycorrhizal partners of conifers — primarily Pinus and Pseudotsuga — documenting the genus's involvement in phosphate and nitrogen cycling in nutrient-limited forest soils. Researchers searching for peer-reviewed evidence on Rhizopogon fulvigleba will find the index points largely to congeners: R. luteolus, R. roseolus, R. subareolatus, and Rhizopogon sp.

On phosphorus: research on R. luteolus identified a phosphate transporter gene (RlPT) that is upregulated under Pi starvation and partially restored phosphate transport activity in a yeast complementation assay, with a Km of 57.90 μmol/L Pi. A separate study found Rhizopogon ectomycorrhizas conferred consistently higher nitrate uptake on colonized pine roots than non-mycorrhizal roots, irrespective of ambient nitrate concentration.

Nursery inoculation trials with Rhizopogon on Pinus pinaster at a post-fire reforestation site reported 1.5-fold greater stem height in inoculated seedlings after five growing seasons, with the inoculated fungal strains persisting in the field. These findings are reported in peer-reviewed research on related species; no abstract in the indexed set directly characterizes R. fulvigleba itself in a controlled trial.
