- Key message
- Promoter-GUS analysis of OsCAD2 (pCAD::GUS) in the internode, sheath, and roots revealed that GUS expression was strong in tissues that accumulated high levels of lignin
- Consistent with this finding, extracts from roots, internodes, hulls, and panicles of the gh2 plants exhibited drastically reduced CAD activity and undetectable sinapyl alcohol dehydrogenase activity
- OsCAD2 is the major CAD gene responsible for monolignol biosynthesis in rice culm
- Solid-state nuclear magnetic resonance (NMR) and X-ray diffraction analyses of rice cell walls revealed that and OsCAD2 deficiencies contributed to the disruptions of the cellulose crystalline network
- Further, OsCAldOMT1 deficiency contributed to the increase of the cellulose molecular mobility more prominently than OsCAD2 deficiency, resulting in apparently more loosened lignocellulose molecular assembly
- A set of rice mutants harboring knockout mutations in either or both OsCAldOMT1 and OsCAD2 was generated in part by genome editing and subjected to comparative cell wall chemical and supramolecular structure analyses
- Connection
- GH2~OsCAD2, OSHB4~OsHox32, The OsmiRNA166b-OsHox32 pair regulates mechanical strength of rice plants by modulating cell wall biosynthesis, OsHox32 binds to the promoters of OsCAD2 and OsCESA7 to suppress the expression levels of these two genes
- GH2~OsCAD2, OSHB4~OsHox32, The OsmiRNA166b-OsHox32 pair regulates mechanical strength of rice plants by modulating cell wall biosynthesis, The suppression of OsCAD2 is synergistic when OsHox32 is co-expressed with OSH15 (Oryza sativa homeobox 15)
- D6~OSH15~Oskn3~RLB, GH2~OsCAD2, The OsmiRNA166b-OsHox32 pair regulates mechanical strength of rice plants by modulating cell wall biosynthesis, The suppression of OsCAD2 is synergistic when OsHox32 is co-expressed with OSH15 (Oryza sativa homeobox 15)
- GH2~OsCAD2, OsCesA7, The OsmiRNA166b-OsHox32 pair regulates mechanical strength of rice plants by modulating cell wall biosynthesis, OsHox32 binds to the promoters of OsCAD2 and OsCESA7 to suppress the expression levels of these two genes
- GH2~OsCAD2, RLM1, RLM1, Encoding an R2R3 MYB Transcription Factor, Regulates the Development of Secondary Cell Wall in Rice., A series of experiments, including the transcription factor-centered technology, DNA-binding assay, and electrophoretic mobility shift assay, verified that RLM1 can bind to the promoter of OsCAD2, a key gene responsible for lignin biosynthesis in rice
- GH2~OsCAD2, OsNAC055, Transcription factor OsNAC055 regulates GA-mediated lignin biosynthesis in rice straw., Further ChIP-qPCR analysis and transient transactivation assays indicated that OsNAC055 directly activates rice lignin biosynthetic genes CINNAMOYL-CoA REDUCTASE 10 (OsCCR10) and CINNAMYL ALCOHOL DEHYDROGENASE 2 (OsCAD2) by binding to their promoters
