3. Diego Yoshikay, Jun Shigeto, Yusuke Yokoyama, Yuji Tsutsumi, The contribution of CWPO-C to primary stage of plant growth and organogenesis, 5th Symposium of Biotechnology Applied to Lignocelluloses, 2018.08, Cationic cell-wall-bound peroxidase (CWPO-C) from poplar has been believed as a lignification-specific peroxidase, but direct evidence that demonstrates the role of CWPO-C remained unachieved. To promote better understanding about CWPO-C functions, transcriptional analysis of CWPO-C using laser microdissection, gene expression quantification and reporter gene techniques were performed. The results showed that CWPO-C expressed in the most of young tissues including xylem of upper stem, but scarcely expressed in interfascicular fiber and undifferentiated tissue such as apical meristem and cambium. Heterologous overexpression of CWPO-C in Arabidopsis inhibited plant growth and caused stem curvature. In addition, CWPO-C expressed in the outer site of the curved stem that was subjected to gravity stress. These results indicate that CWPO-C plays a role in cell elongation and differentiation; suggesting a new aspect to the role of CWPO-C. CWPO-C may contribute to catabolism of plant hormones such as auxin, involved in cell elongation, differentiation and geotropism..

Yuji Tsutsumi, Jun Shigeto, Hiroki Honjo, Generation of lignin polymer models via dehydrogenative polymerization of coniferyl alcohol and sinapyl alcohol via plant peroxydase involved in lignification and analysis of the resulting DHPs by MALDI-TOF analysis, 29th International Conference of Polyphenols, 2018.07, The mechanism of lignin dehydrogenative polymerization (DHP), made by mean of horseradish peroxidase (HRP), has been studied. Interestingly, HRP is efficient for guaiacyl type polymer formation (G-DHPs), but is not efficient in case of syringyl type DHPs (S-DHPs). It was previously demonstrate that lignification-related Arabidopsis peroxidases, AtPrx2, AtPrx25 and AtPrx71, and cationic cell-wall-bound peroxidase (CWPO-C) from the poplar are successful to oxidize syringyl- and guaiacyl-type monomers and larger lignin-like molecules. This is the reason why in the present study the DHP formation by means of these recombinant peroxidases was tested, and all these enzymes were successful for formation of both G-DHP and S-DHP in acceptable yields. CWPO-C led to S-DHP molecular size distribution similar to that of isolated lignins..

10. Yuji Tsutsumi, Manami Takeuchi, Screening of monolignol transport protein in Arabidopsis thaliana, International Symposium on Wood Science and Technology 2015, 2015.03, Screening of monolignol transport protein in Arabidopsis thaliana

Monolignols are synthesized in the cytosol and transported to the cell wall to biosynthesize linign. It was reported that one of ATP-binding cassette (ABC) proteins, AtABCG29, is involved in the transportation of p-coumaryl alcohol, however, there have been no report on other monolignols for guaiacyl and syringyl lignin, which are major constitute units of angiosperm lignin. In this study, 9 genes including ABC proteins were selected as monoligol transport candidates among the genes those expressions were largely changed during the tracheary element differentiation of Arabidopsis cell culture, and T-DNA insert mutants of these genes were subjected to lignin analyses. There were no difference in both lignin content and S/G ratio between wild type and each knockout mutant. The expression analysis of each gene in the several organs did not show specificity in the stem unlike ABCG29. These results suggest that the candidate genes may not be involved in monolignol transportation in the Arabidopsis stem.
In the next screening we focus on evolutionally altered genes. Vascular plants have developed vascular bundle to conduct water and support their own body. Along with this evolution, lignin biosynthesis system had been also evolved. ABC transporter genes were compared between Arabidopsis thaliana as vascular plant and Physcomitrella patens as nonvascular plant, and 66 ABC proteins were found to be vascular plant specific. Further 28 ABCG subfamily genes among them were chosen as candidates, because some ABCG subfamily proteins have been reported to be related to secondary metabolism. The monolignol transport assay using transformed yeast with candidate gene is also performed to screen potential monolignol exporter.

12. Yuji Tsutsumi, Jun Shigeto, Kaori Ohira, Ryunosuke Takao, Masaaki Kamada, Expression and subcellular localization analysis of poplar cationic cell-wall-bound peroxidase and its Arabidopsis putative homologs involved in lignification, Lignobiotech III, 2014.10, [URL], Genetic engineering of gene which encodes peroxidase responsible for lignin polymerization is expected as an effective technique to change lignin content and structure in plant, but it is still far from the industrial application. This is because of the lack of fundamental knowledge about physiological functions of peroxidases. Limited number of peroxidases involved in lignification were identified in some plants, and little is known about their tissue-specific expression and subcellular localization pattern.
Cationic cell-wall-bound peroxidase (CWPO-C) from poplar has been verified to serve oxidation of both monolignols and lignin polymer, for the first time [1, 2]. This oxidation property is good as the enzyme responsible for lignin polymerization. In addition, AtPrx-2, 25 and 71 which have high amino acid similarity to CWPO-C were shown to contribute to stem lignification of Arabidopsis [3], and have CWPO-C-like oxidation property. In this study, tissue-specific expression and localization of CWPO-C and its Arabidopsis putative homologs, AtPrx-2, 25 and 71, were investigated. Promoter assay using transgenic Arabidopsis line carrying a CWPO-C promoter driven β-glucuronidase construct revealed that CWPO-C expressed in young developing tissues including protoxylem, except root tip. We also generated transgenic Arabidopsis T87 cultured cell overexpressed CWPO-C-EGFP fusion protein, and the fluorescence was observed in helical cell wall thickening of the cell differentiated into tracheary element. This presentation will discuss about the role of each peroxidase in the lignification process from a viewpoint of expression and subcellular localization patterns of CWPO-C, AtPrx-2, 25 and 71.

14. 堤 祐司, 重藤 潤, OXIDATION ACTIVITIES OF PLANT PEROXIDASES INVOLVED IN LIGNIFICATION, Oxizymes, 2014.07, Lignin is a main component of vascular plant cell walls and possesses a complex and irregular structure. In angiosperms, lignins consist mainly of two monolignols, coniferyl (4-hydroxy-3-methoxycinnamyl) and sinapyl (3,5-dimethoxy-4-hydroxycinnamyl) alcohols, which polymerize through at least five different linkage types and result in 4-hydroxy-3-methoxyphenyl (guaiacyl) and 3,5-dimethoxy-4-hydroxyphenyl (syringyl) units, respectively. Monolignols are supplied to the cell wall and polymerized to fill, together with hemicellulose, the spaces between cellulose microfibrils; this polymerization proceeds through oxidative coupling catalyzed by plant peroxidases. Based on the ‘‘End-wise’’ polymerization process, monolignol radicals can be coupled to a growing lignin polymer to produce a lignin macromolecule [1].
However, most known plant peroxidases, including horseradish peroxidase (HRP) and AtPrx53, can only oxidize p-coumaryl and coniferyl alcohols. This characteristic difference has led to controversy regarding the oxidation mechanism of sinapyl alcohol, lignin oligomers and polymers by plant peroxidases. Until now, CWPO-C, a peroxidase isozyme from Populus alba L., has only been verified to serve combined oxidation activity for sinapyl alcohol, lignin ligomers and polymer [2].The tyrosine 74 and tyrosine 177 located on the surface of CWPO-C, instead of the heme pocket, take a central role in the oxidation of substrates [3].
Previously, we has focused on seven Arabidopsis plant peroxidases selected using amino acid similarities to CWPO-C as a probe and found that AtPrx2 or AtPrx25 deficiency led both decreased total lignin content and altered lignin structure, including cell wall thinning in the stem. In addition, AtPrx71 deficiency led an altered stem lignin structure, although the lignin content is not decreased. These results provided in vivo evidence that AtPrx-2, 25, and 71 are involved in Arabidopsis stem lignification [4].
The present study explored the oxidation activities of three plant peroxidases, AtPrx-2, 25, and 71, which have been already shown to be involved in lignification Arabidopsis stem. Recombinant proteins of these peroxidases (rAtPrxs) were produced in Escherichia coli as inclusion bodies and successfully refolded to yield their active forms. The specific activities of rAtPrx-2, 25 and 71 toward two syringyl compounds (2,6-dimethoxyphenol and syringaldazine) were higher than that of HRP-C and rAtPrx53. Interestingly, rAtPrx2 and rAtPrx71 oxidized syringyl compounds more efficiently than guaiacol. Moreover, assays with ferrocytochrome c showed that AtPrx2, AtPrx25, and AtPrx71 possessed the ability to oxidize large molecules. This characteristic presumably originate in a protein radical. These results provide the evidence that the plant peroxidases responsible for lignin polymerization are able to directly oxidize all lignin precursors. We will also present an assay of dehydrogenative polymer formed from monolignols with rAtPrxs.
