Ultrastructural analysis of engineered rice lines reveals ferulate cross-linking as a key factor mediating lignocellulose supramolecular assembly in grass cell walls

Senri Yamamoto, Osama Ahmed Afifi, Pingping Ji, Ryosuke Kusumi et autres

Abstract Within the secondary cell walls of vascular plants, cellulose, hemicelluloses, and lignin associate via various covalent and non-covalent linkages to form an intricate supramolecular assembly. Although the chemical structures and cross-linking levels of the lignin– hemicellulose matrix exhibit substantial diversity in …

PtrSHR1 coordinates vascular cambium proliferation and xylem lignin biosynthesis to regulate wood formation in Populus trichocarpa

Jinfeng Zhao, Yanjie Chen, Xiufang Dai, Li‐Wei Su et autres

Vascular cambium produces cells to form xylem, or wood, in tree stems. Here, we explored transregulatory pathways in this cell lineage development. We tested 20 of the 95 putative vascular cambium-specific (VCS) transcription factor genes through gain-of-function transgenesis in Black cottonwood (Populus …

Engineering 2‐Pyrone‐4,6‐Dicarboxylic Acid Production Reveals Metabolic Plasticity of Poplar

Nidhi Dwivedi, Pingping Ji, Yang Tian, Dasmeet Kaur et autres

Woody biomass is a promising source of fermentable sugars for biofuels and bio-based chemicals, but its industrial use is limited by the costly biorefinery process. A viable strategy to reduce costs involves enhancing both biomass processability and the generation of high-value co-products. …

Stacked mutations disrupting syringyl and p ‐coumaroylated lignin biosynthesis result in lignin dominated by guaiacyl units in rice

Pingping Ji, Osama Ahmed Afifi, Senri Yamamoto, Yuriko Osakabe et autres

The aromatic composition of lignin significantly impacts the usability of lignocellulosic biomass. In eudicots, transgenic and mutant lines with elevated guaiacyl (G) or syringyl (S) lignin units have been successfully generated by manipulating the expression level of genes encoding CONIFERALDEHYDE 5-HYDROXYLASE (CAld5H). …

Essential yet dispensable: The role of CINNAMATE 4-HYDROXYLASE in rice cell wall lignification

Supatmi Supatmi, Pui Ying Lam, Senri Yamamoto, Osama Ahmed Afifi et autres

A comprehensive understanding of the intricate lignin biosynthesis in grasses could contribute to enhancing our ability to utilize grass biomass. CINNAMATE 4-HYDROXYLASE (C4H), in conjunction with PHENYLALANINE AMMONIA-LYASE (PAL), initiates the entry of phenylalanine into the cinnamate/monolignol pathway, leading to the production …

Yiman Luo, Qianya Su, Yang-li Zhu, Pingping Ji et autres

The histology of MCC varies. Rendering a correct diagnosis of MCC requires adequate sampling, close correlation with clinical history and rational use of immunohistochemical staining. The treatment requires standardized surgery, postoperative radiotherapy and multimodal chemotherapy. Immunotherapy may replace the traditional treatment in …

Protein kinase C regulates tyrosine phosphorylation of pp125FAK in platelets adherent to fibrinogen

Beatrice Haimovich, N Kaneshiki, Pingping Ji

Platelet adhesion to immobilized fibrinogen stimulates the induction of tyrosine phosphorylation of multiple proteins. However, platelet spreading and tyrosine phosphorylation of three proteins, the focal adhesion kinase pp125FAK and proteins of 101 and 105 kD (pp101 and pp105), require a second adenosine …
