Résumé
OBJECTIVE: To characterize the fungal communities in agarwood wood from Hainan province and Guangdong province. METHODS: Fungal ITS genes in the agarwood wood were analyzed by high-throughput pyrosequencing using Illumina HiSeq system and bioinformatically. RESULTS: The fungal microbiomes exhibited much similarity among the samples from different regions in each province. And there were notable differences between Guangdong province and Hainan province. Moreover, the fungal communities in the agarwood wood from Hainan Province showed higher diversity and richness than that in the agarwood wood from Guangdong province. At the phylum level, Ascomycota most dominated in the agarwood wood, followed by Basidiomycota. Ascomycota dominated in the agarwood wood from Haikou, Wanning, Ledong, Danzhou and Dongguan regions. Basidiomycota dominated in the agarwood wood from Huazhou region. At the class level, agaricomycetes dominated in the agarwood wood from Huazhou region. Sordariomycetes dominated in the agarwood wood from Dondguan and Danzhou regions, Dothideomycetes dominated in the agarwood wood from Haikou, Ledong and Wanning regions. At the order level, Pleosporales dominated in the agarwood wood from Haikou, Ledong, Wanning and Dondguan regions. Trechisporales and Polyporales dominated in the agarwood wood from Huazhou and Danzhou regions, respectively. At the genus level, Lignosphaeria dominated in the agarwood wood from Haikou and Wanning regions, Perenniporia and Pyrigemmula dominated in the agarwood wood from Ledong and Danzhou regions, respectively. Phaeoacremonium dominated in the agarwood wood from Huazhou and Dondguan regions. Agarwood wood from different regions contained different dominate fungal populations. CONCLUSION: The fungi in the agarwood wood from Hainan province has higher diversity and richness than that in the agawood wood from Guangdong province. Agarwood wood from different regions has distinct fungal communities.
