Summary: This study investigates the effects of bio-organic fertilizers on the physiological characteristics and leaf nutrient content of Qi-Nan agarwood seedlings. It aims to provide a theoretical basis for the efficient cultivation of Qi-Nan. The experiment used a Randomized complete block design and found that the application of bio-organic fertilizer significantly enhanced plant growth, increased the contents of various nutrients, and reduced stress indices. Redundancy analysis revealed the main factors affecting seedling growth, while principal component analysis and membership function analysis showed significant variations among the fertilizer groups.

Summary: The taxonomic classification and chemical diversity of agarwood produced by three Chi-Nan germplasms were evaluated, confirming the origin species as A. sinensis. Compared to ordinary agarwood, Chi-Nan agarwood had higher levels of alcohol extract and more abundant sesquiterpenoids, but lower diversity of 2-(2-phenylethyl) chromones. It was proposed that there are two chemotypes in A. sinensis, Chi-Nan type and Ordinary type, providing a reference for molecular mechanism studies of agarwood formation.

Summary: This study investigated the differences between Qi-Nan and OA clones in agarwood formation and their correlation with morphological, anatomical, and physiological characteristics. The results showed that Qi-Nan had higher agarwood yield and essential oil content than OA, and it had a stronger photosynthetic basis, more efficient xylem structural basis, and higher carbon source utilization rate.

Summary: This study reveals the transcriptional response of Aquilaria sinensis to mechanical wounding during agarwood formation. The study shows that the response of A. sinensis to mechanical wounding includes secondary metabolic processes, signal transduction, and transcriptional regulation. Additionally, the study identifies key genes involved in lignin and sesquiterpene synthesis, providing resources for molecular breeding and shedding light on the molecular mechanisms of agarwood formation.

Summary: In this study, the JAZ family members in Aquilaria sinensis were characterized and their correlations with WRKY transcription factors were explored. Twelve potential AsJAZ proteins and sixty-four potential AsWRKY transcription factors were identified. Tissue-specific or hormone-induced expression patterns were observed for AsJAZ and AsWRKY genes. The study also found a potential relationship between AsJAZ4 and several AsWRKY transcription factors, which was confirmed by experiments.

Summary: By comparing ordinary A. sinensis and Chi-Nan germplasm, this study revealed the molecular mechanism underlying wounding stress in different A. sinensis germplasm resources and identified 13 candidate genes related to high agarwood-producing capacity. These findings are important for the development of functional molecular markers and the rapid breeding of highly responsive Aquilaria lines.

Summary: By comparing the chemical constituents and fragrant components of cultivated Qi-Nan (CQN) agarwood with wild harvested Qi-Nan (WQN) agarwood, significant differences were found between the two types, with WQN agarwood exhibiting higher chemical diversity and CQN agarwood having higher contents of (59) and (60). Additionally, guaiane-furans sesquiterpenes found only in WQN agarwood of A. sinensis may serve as a chemical marker for this specific type of agarwood.

Summary: Current artificial agarwood-inducing techniques have low yields and produce low-quality agarwood. This study used a novel agarwood-inducing method (Agar-Bit) to extract a complete agarwood column from cultivated Aquilaria sinensis trees and analyzed its chemical composition. The results showed that the resin and microstructure changed along the agarwood column, and six chromones varied in different layers. Volatile components were mainly distributed in the agarwood layer, but important chromones were also detected in the brown inner layer. The findings provide insights for optimizing production and efficiency in agarwood induction and understanding the formation mechanism.

Summary: Five new eudesmane-type sesquiterpenoids (aquisinenoids F-J (1-5)) and five known compounds (6-10) were isolated from Aquilaria sinensis. Their structures and absolute configurations were identified using spectroscopic analyses and computational methods. Although no anticancer or anti-inflammatory activities were observed, the study provided insights into the structure-activity relationships (SAR).

Summary: Research showed that fungi extracted from wild agarwood with high oil content can effectively improve the yield and quality of agarwood. Specific species of fungi have positive effects on agarwood formation. After a certain period of inoculation, agarwood produced from Aquilaria sinensis had higher quality with changes in content of different chemical components.
