| Résumé: | Copyright © 2025 Elsevier Masson SAS. All rights reserved. Fuling (Wolfiporia hoelen) is a widely used traditional Chinese herbal medicine. Pachymic acid is the representative bioactive lanosterol triterpenoid in Fuling, with the potential for developing anti-tumor drugs. However, the gene involved in the modification of lanosterol is unclear. In this study, the genome of W. hoelen XJ28 was sequenced and assembled at the chromosome level, and the CYP5035D1C31 is identified as the key enzyme responsible for lanosterol modification by CRISPR/Cas9 gene editing and heterologous expression. The genome of Chinese W. hoelen XJ28 is 59.87 Mb and may have diverged from American M. cocos MD104 about 48.5 million years ago. CYP5035D1C31 was selected as a candidate for lanosterol modification via co-localization and co-expression with lanosterol synthase. Gene editing of CYP5035D1C31 by CRISPR/Cas9 in W. hoelen confirmed that CYP5035D1C31 is the key enzyme responsible for lanosterol C-16 hydroxylation or C-20 methyl carboxylation in vivo of W. hoelen. Moreover, the pachymic acid was detected by HPLC-Q-TOF-MS after heterologous expression of CYP5035D1C31. This is the first study to functionally characterize the key CYP450 in Chinese herbal medicine W. hoelen, providing important insights for biological research, bioproduct improvement, and planting development of the Fuling industry |
