            Cellulolytic enzyme lignin (CEL) and milled wood lignin (MWL) were prepared by three different ball-milling methods. The structure of CEL at various yields was elucidated and compared with MWL using wet chemical analysis, FTIR and solution-state NMR techniques. Results show that ball milling of wood degrades β-O-4 structures in lignin. However, even after extensive ball milling, less than 25% of the β-O-4 structures were degraded. The extent of degradation was less for softwood than for hardwood lignin. Extractable lignin yield, either MWL or CEL, was the best way to assess the extent and effect of ball milling. CEL is preferred over MWL, as it can be isolated in higher yield with less degradation. CEL was isolated at yields ranging from 20% to 86%. Over this range the CEL had similar structures, suggesting that lignin in the secondary wall is uniform in structure. The residual enzyme lignin (REL) was structurally different from CEL and may originate mainly from the middle lamella. In this paper we propose a new procedure for the isolation of lignin for use in structural studies, whereby wood is sufficiently milled and successively extracted to produce three lignin fractions representing the total lignin in wood.}, number={4}, journal={HOLZFORSCHUNG}, author={Hu, Zhoujian and Yeh, Ting-Feng and Chang, Hou-min and Matsumoto, Yuji and Kadla, John F.}, year={2006}, month={Jul}, pages={389–397} }

            To better understand the within-tree variations between juvenile wood, mature wood, and compression wood, wood from a 35-year-old mature bent loblolly pine was separated into seven groups by different positions in the tree. Morphological and chemical structure analyses, including fiber quality, X-ray diffraction, sugar and lignin content analysis, as well as nitrobenzene oxidation, ozonation, and advanced NMR spectroscopy, were performed. Fiber properties were significantly different for tree-top juvenile normal wood and tree-bottom juvenile normal wood, juvenile normal and mature normal wood, juvenile compression and mature compression wood. However, differences in the chemical structure and composition were less significant within the specific tissues indicated above.}, number={1}, journal={HOLZFORSCHUNG}, author={Yeh, TF and Braun, JL and Goldfarb, B and Chang, HM and Kadla, JF}, year={2006}, month={Jan}, pages={1–8} }

            Genetic engineering of trees has generated a large amount of interest in the development of highly improved transgenic trees. To efficiently monitor and control the properties of the transgenic products, a rapid, mini-scale analytical method is required. Transmittance near-infrared (NIR) spectroscopy was chosen as a fast analysis tool for characterizing the chemical properties of the transgenic products. Pellets were prepared from 75 mg of wood meal and directly scanned using transmittance NIR spectroscopy. Very strong correlations were obtained between the NIR data and conventional wet-chemistry results for the lignin content, S/G ratio, cellulose and xylose content. The results indicate that transmittance NIR is a powerful tool for determining and screening the chemical properties of transgenic trees.}, number={1}, journal={HOLZFORSCHUNG}, author={Yamada, T and Yeh, TF and Chang, HM and Li, LG and Kadla, JF and Chiang, VL}, year={2006}, month={Jan}, pages={24–28} }

To determine whether JW and CW can be distinguished metabolically, we compared gas chromatographic profiles of 25 polar metabolites from rooted cuttings of a single loblolly pine (Pinus taeda L.) clone raised in controlled environment chambers and subject to three treatments: (1) grown erect with minimal wind sway (control); (2) swayed by wind from oscillating fans; and (3) with 30-cm growth increments successively bent at an angle of 45 degrees to the vertical. Profiles were compared by principal component analysis. Substantial increases in abundances of coniferin and p-glucocoumaryl alcohol separated immature JW-forming xylem tissues of the control trees from the CW-forming xylem of the bent and swayed trees.}, number={11}, journal={TREE PHYSIOLOGY}, author={Yeh, Ting-Feng and Morris, Cameron R. and Goldfarb, Barry and Chang, Hou-Min and Kadla, John F.}, year={2006}, month={Nov}, pages={1497–1503} }

            In conifers, juvenile wood (JW) is always associated with compression wood (CW). Due to their similar properties, there is a common belief that JW is the same as CW. To resolve whether JW is identical to CW, 24 rooted cuttings of one loblolly pine clone were planted in growth chambers under normal, artificial bending, and windy environments. The results show that the morphology of JW is significantly different from CW. Furthermore, chemical analyses revealed that JW and CW are significantly different in chemical composition. Our results indicate that JW is different from CW, and the wood formed under a controlled windy environment is a mild type of compression wood.}, number={6}, journal={HOLZFORSCHUNG}, author={Yeh, TF and Goldfarb, B and Chang, HM and Peszlen, I and Braun, JL and Kadla, JF}, year={2005}, pages={669–674} }
