Thermo-mechanical Densification of Populus tomentosa var. tomentosa with Low Moisture Content
This study used thermo-mechanical densification technology to compress low-moisture content (3~5%) rapid-growth Populus tomentosa var. tomentosa trees to produce specimens with a low-compression ratio (small volume loss) and a uniform density profile and desirable properties. Furthermore, the densified specimens were subjected to post-heat treatment at 180, 190, and 200 °C for 2, 3, and 4 h, re...
متن کاملAntioxidative Low Molecular Weight Extractives from Triploid Populus Tomentosa Xylem
Triploid Populus tomentosa Carr. (Salicaceae) is a good alternative to meet the increasing need of the global pulp and paper industry. Meanwhile, the xylem of this species could be a useful bioresource to develop low molecular extractives with significant bioactive potential. In the present work, a phytochemical investigation on aqueous EtOH extractives of Triploid P. tomentosa xylem, by system...
متن کاملAssociation of Allelic Variation in PtoXET16A with Growth and Wood Properties in Populus tomentosa
Xyloglucan endo-transglycosylases (XETs) modify the xyloglucan-cellulose framework of plant cell walls and, thus, affect cell wall expansion and strength. Dissecting the mechanism by which natural variation in XETs affects wood properties can inform breeding efforts to improve wood quality and yield traits. To this end, we isolated a full-length PtoXET16A cDNA clone from Populus tomentosa. Real...
متن کاملIdentification and allelic dissection uncover roles of lncRNAs in secondary growth of Populus tomentosa
Long non-coding RNAs (lncRNAs) function in various biological processes. However, their roles in secondary growth of plants remain poorly understood. Here, 15,691 lncRNAs were identified from vascular cambium, developing xylem, and mature xylem of Populus tomentosa with high and low biomass using RNA-seq, including 1,994 lncRNAs that were differentially expressed (DE) among the six libraries. 3...
متن کاملCrystal structures of a Populus tomentosa 4-coumarate:CoA ligase shed light on its enzymatic mechanisms.
4-Coumaric acid:CoA ligase (4CL) is the central enzyme of the plant-specific phenylpropanoid pathway. It catalyzes the synthesis of hydroxycinnamate-CoA thioesters, the precursors of lignin and other important phenylpropanoids, in two-step reactions involving the formation of hydroxycinnamate-AMP anhydride and then the nucleophilic substitution of AMP by CoA. In this study, we determined the cr...
