Abietic acid an activator of basidiospore germination in ectomycorrhizal species of the genus suillus boletaceae






Experimental Mycology 11(4): 360-363

Abietic acid an activator of basidiospore germination in ectomycorrhizal species of the genus suillus boletaceae

Germination of basidiospores from four ectomycorrhiza-forming Suillus species (S. granulatus, S. grevillei, S. luteus, and S. variegatus) was induced by exposing the spores to extracts or exudates from roots of Scotch pine (Pinus sylvestris L.). An active compound was contained in the lipophilic phase obtained by extraction of pine roots with chloroform/methanol. It was isolated and identified as abietic acid, a diterpene resin acid. With S. granulatus, the bioassay species, abietic acid caused germination at concentrations down to 10-7 M.
