Physiological and biochemical mechanisms of drought regulating the size and color of heartwood in Dalbergia odorifera.

Drought has been found to affect the size and color of precious heartwood of Dalbergia odorifera, but the mechanism remains unclear. For this purpose, we performed the measurement of heartwood size, color, and flavonoid content and composition in a 15-year-old mixed plantation of D. odorifera and Santalum album that had been subjected to two levels of rainfall exclusion and control treatments for seven years, and carbon isotope labeling and anatomical observation in 2-year-old potted D.

Anatomical, chemical and endophytic fungal diversity of a Qi-Nan clone of (Lour.) Spreng with different induction times.

Recently, some new Qi-Nan clones of (Lour.) Spreng which intensively produces high-quality agarwood have been identified and propagated through grafting techniques. Previous studies have primarily focused on ordinary and the differences in composition when compared to Qi-Nan and ordinary .

Effects of Drought and Host on the Growth of Seedlings in Pot Culture.

is a semi parasitic plant and its growth is often restricted due to a lack of a host or water during plantation establishment. In this study, the effects of water and the host on the growth of seedlings were studied in pot culture. The results showed that the net photosynthetic rate and height of seedlings decreased significantly under drought stress.

Changes in Non-Structural Carbohydrates, Wood Properties and Essential Oil During Chemically-Induced Heartwood Formation in .

The highly valuable heartwood of T. Chen, known as in traditional Chinese medicine, is formed very slowly, and there is a need to better understand the process and promote heartwood formation. Chemical induction is considered to be one of the promising methods to induce heartwood formation.

The chromosome-level draft genome of Dalbergia odorifera.

Background: Dalbergia odorifera T. Chen (Fabaceae) is an International Union for Conservation of Nature red-listed tree. This tree is of high medicinal and commercial value owing to its officinal, insect-proof, durable heartwood.

Characteristics of the soil microbial community in the forestland of .

Characterizing soil microbial community is important for forest ecosystem management and microbial utilization. The microbial community in the soil beneath , an important woody edible oil tree in China, has not been reported before. Here, we used Illumina sequencing of 16S and ITS rRNA genes to study the species diversity of microorganisms in forest land in South China.

Synergistic Roles of Biphasic Ethylene and Hydrogen Peroxide in Wound-Induced Vessel Occlusions and Essential Oil Accumulation in .

The heartwood of (), named "Jiang Xiang" in traditional Chinese medicine, is highly valuable. Mechanical wounding induced the production of "Jiang Xiang" in Ethylene and hydrogen peroxide (HO) are proposed to play vital roles in wound signaling. However, little is known about the role of ethylene or HO in the wound-induced formation of vessel occlusions and biosynthesis of "Jiang Xiang" in .

Surrogate analyte approach for quantitation of endogenous NAD(+) in human acidified blood samples using liquid chromatography coupled with electrospray ionization tandem mass spectrometry.

A high-performance liquid chromatography tandem mass spectrometry (LC-MS/MS) assay for the quantitative determination of NAD(+) in human whole blood using a surrogate analyte approach was developed and validated. Human whole blood was acidified using 0.5N perchloric acid at a ratio of 1:3 (v:v, blood:perchloric acid) during sample collection.

Molecular analysis and structure-activity relationship modeling of the substrate/inhibitor interaction site of plasma membrane monoamine transporter.

Plasma membrane monoamine transporter (PMAT) is a new polyspecific transporter that interacts with a wide range of structurally diverse organic cations. To map the physicochemical descriptors of cationic compounds that allow interaction with PMAT, we systematically analyzed the interactions between PMAT and three series of structural analogs of known organic cation substrates including phenylalkylamines, n-tetraalkylammonium (n-TAA) compounds, and β-carbolines. Our results showed that phenylalkylamines with a distance between the aromatic ring and the positively charged amine nitrogen atom of ∼6.
