Biodiversity of wood-decaying fungi in French Guiana sequences of the small subunit (SSU) of ribosomal (r) DNA and the two primer pairs SR6/SR10R and SR7/SR1R
2019 - IRG/WP 19-10936
Fungi from tropical regions are currently under-represented in the classification system. Indeed, difficult access to tropical forests makes it complicated to study fungus species in such environments, unlike in European zones where fungal diversity and taxonomy are much better known. The purposes of this work were: a) to enhance classification by integrating new data that would bring out the impo...

Characterization of tropical wood-decaying fungi by RFLP analysis of PCR amplified rDNA
1998 - IRG/WP 98-10251
Five brown-rot fungi (Tyromyces palustris, Gloeophyllum trabeum, Antrodia sp., Poria placenta, Coniophora puteana) and three white-rot fungi (Coriolus versicolor, Pycnoporus sanguineus, Lentinus squarrosulus) registred as representative wood-decaying fungi for international standards of wood durability tests have been characterized using molecular tools (PCR/RFLP). The Internal Transcribed Spacer ...

Molecular characterization of M’jej, decaying agent of cedar forests in Morocco
2006 - IRG/WP 06-10593
Cedar wood is well appreciated since thousand years even though its economical importance is limited because of its world distribution restricted to some Mediterranean countries and Himalaya. The most important species, Cedrus atlantica have its biggest population in Morocco (130 000 ha) where it is submitted to fungal diseases. Among them, the locally named “M’jej” reduced notably saw mile ...

NGS analysis of fungal OTUs in Aquilaria sp. from French Guyana, Cambodia, Laos and Thailand
2017 - IRG/WP 17-50328
Aquilaria is a tree species belonging to the Thymeleaceae family. When Aquilaria sp. is injured, it produce agarwood. Agarwood is characterized by a darker wood colour than the healthy one and by a strong perfume that is much esteemed by perfumers and some oriental religious communities. The production of agarwood is presumed to depend of environmental factors, among them fungi. The aim of this wo...

Chemical composition of agarwood of Aquilaria crassna Pierre ex. Lecomte induced by Basidiomycetes from French Guiana
2022 - IRG/WP 22-10988
Aquilaria trees subjected to stress induce the formation of a transformed wood named agarwood. The formation of agarwood is a plant defense mechanism that occur in complex interactions with environmental microorganisms. Agarwood chemical compounds are mainly chromones and oxygenated sesquiterpenes such as eudesmol, agarospirol, jinkoh-eremol and valerianol, which are valued in perfumery. Its deriv...

Chemotaxonomy of the genus Aquilaria (Thymelaeaceae)
2022 - IRG/WP 22-20687
The genus Aquilaria Lam. (Thymelaeaceae) comprises 21 tree species and is mostly found in Southeast Asia. When the tree is infected (fungi, bacteria, etc.), its wood turns brownish or blackish (called agarwood) due to the secretion of an oleoresin in reaction to the infection. The resin is very fragrant and has been sought after and used for centuries by Buddhists, Hindus and Muslims to make incen...

Characterization of the fungal communities associated with Aquilaria crassna Pierre ex Lecomte plantations in French Guiana
2023 - IRG/WP 23-11001
Aquilariais a tree species belonging to the family of the Thymeleaceae. When the tree is wounded, it can produce a blackened wood, also known as agarwood. The blackened wood has a darker colour than healthy wood and gives off a strong fragrance greatly appreciated by perfumers and by certain oriental religious communities. Production of this blackened wood is deemed to depend on environmental fact...
