Abstract

This article focuses on the degradation of seed mucilage from the desert shrub Artemisia sphaerocephala by the fungus Phanerochaete chrysosporium. The study demonstrates that P. chrysosporium not only effectively degrades seed mucilage under optimal conditions (30°C, pH 4.5) with a degradation rate exceeding 93% after 20 days but also produces iron carriers and solubilizes potassium and phosphorus, which may enhance nutrient availability in desert soils. Untargeted metabolomic analysis identified 300 significantly altered metabolites during degradation, with key changes in the biosynthetic pathway of the amino acids valine, leucine, and isoleucine. These findings contribute to understanding the ecological functions of seed mucilage and the role of plant–microbe interactions in desert adaptation.
