Fungal Degradation of Extractives Plays an Important Role in the Brown Rot Decay of Scots Pine Heartwood

open access: yesFrontiers in Plant Science, 2022
Scots pine heartwood is known to have resistance to wood decay due to the presence of extractives, namely stilbenes and resin acids. However, previous studies have indicated that these extractives are degradable by wood decaying fungi.
