To prevent the exploitation of wild agarwood, the development of artificial agarwood through fungal inoculation is a promising method, but finding species that produce efficient high-quality agarwood remains difficult. In this study, a fungal inducer was prepared using wild agarwood containing fungi and high-throughput sequencing was performed to determine its species makeup. Subsequently, it was used to inoculate Aquilaria sinensis(Lour.) Spreng. The induced agarwood (IA), wild agarwood (WA), and nonresinous whitewood (WW) were analyzed for the extract content. In addition, liquid and gas chromatography–mass spectrometry was used to determine the chemical composition of the samples. The results were used to evaluate the quality of the IA. Mortierella humilisLinnem. ex W.Gams, Oidiodendron maius(Barron), and Tolypocladium album(W. Gams) Quandt, Kepler, and Spatafora were the fungal inducers that were discovered to produce agarwood. The extracts from the IA and WA contained 64 and 69 2-(2-phenylethyl)chromones, respectively, while there were none in the WW. Furthermore, 20 (relative content 36.19%) and 27 (relative content 54.92%) sesquiterpenes were identified in the essential oils of the IA and WA, respectively, and none were identified in the WW. The fungal inducer that was prepared from the WA effectively improves the quality of the agarwood, which is extremely similar to that of the WA.

真菌沉香与野生沉香品质的相似性

为了防止野生沉香的开发，通过真菌接种开发人工沉香是一种很有前景的方法，但寻找能够生产高效优质沉香的物种仍然很困难。在本研究中，利用含有真菌的野生沉香制备真菌诱导剂，并进行高通量测序以确定其物种组成。随后，它被用来接种沉香(Aquilaria sinensis (Lour.) Spreng)。分析了诱导沉香 (IA)、野生沉香 (WA) 和无树脂白木 (WW) 的提取物含量。此外，还使用液相和气相色谱-质谱法来确定样品的化学成分。结果用于评估 IA 的质量。矮被孢霉。ex W.Gams、Oidiodendron maius (Barron) 和Tolypocladium album (W. Gams) Quandt、Kepler 和 Spatafora 是被发现用于生产沉香的真菌诱导剂。IA 和 WA 的提取物分别含有 64 和 69 个 2-(2-苯乙基)色酮，而 WW 中则不含。此外，在IA和WA的精油中分别鉴定出20种（相对含量36.19%）和27种（相对含量54.92%）倍半萜，而在WW中未鉴定出倍半萜。由WA制备的真菌诱导剂有效提高了沉香的品质，与WA极为相似。
