Adapted molecular methods to unravel the recalcitrant mycorrhizal associations of Aucoumea klaineana Pierre.

Understanding the role of root microbiota is crucial in sustainable forest management but remains challenging, especially for tropical trees. We developed an efficient and low-toxicity method to extract and amplify the fungal DNA associated with Aucoumea klaineana Pierre fine roots. To improve DNA quality, we optimized a commercial extraction kit by incorporating activated charcoal and modifying incubation periods.
