Journal ArticleDOI
Licodione Synthase, a Cytochrome P450 Monooxygenase Catalyzing 2-Hydroxylation of 5-Deoxyflavanone, in Cultured Glycyrrhiza echinata L. Cells.
TL;DR: The reaction mechanism of licodione synthase is likely to be 2-hydroxylation of the flavanone molecule and subsequent hemiacetal opening and is possibly the same as the previously suggested mechanism of flavone synthase II from soybean and, furthermore, closely related to isoflav one synthase from Pueraria lobata.
Journal ArticleDOI
Activation tagging approach in a model legume, Lotus japonicus.
Ryujiro Imaizumi,Shusei Sato,Nanako Kameya,Ikuo Nakamura,Yasukazu Nakamura,Satoshi Tabata,Shin-ichi Ayabe,Toshio Aoki +7 more
TL;DR: The transcripts of four genes adjacent to T-DNA out of 11 genes tested were increased in the T1 generation, demonstrating that gene and exon activation effects by the newly developed tagging vector are heritable.
Journal ArticleDOI
Efficient Agrobacterium-mediated transformation of Lotus japonicus with reliable antibiotic selection
TL;DR: A new procedure for transforming a model legume, Lotus japonicus, that yields transformed plants from transverse cotyledon segments without contamination from the presence of non-transformants that survived the antibiotic selection is developed.
Journal ArticleDOI
Transcriptional control of the dihydroflavonol 4-reductase multigene family in Lotus japonicus
TL;DR: Ectopic expression of a combination of the transcription factors MYB, bHLH, and WDR showed that only the DFR2 promoter was activated, indicating that each member of the D FR gene family is regulated independently.
Journal ArticleDOI
New scheme of the biosynthesis of formononetin involving 2,7,4'-trihydroxyisoflavanone but not daidzein as the methyl acceptor.
TL;DR: A novel pathway of formononetin biosynthesis involving 2,7,4′-trihydroxyisoflavanone as the methyl acceptor is proposed.
