Arabidopsis contains only one functional dihydroflavonol 4-reductase (DFR) gene, but several DFR-like genes encoding proteins with the conserved NAD(P)H binding domain. At4g35420, named DRL1 (Dihydroflavonol 4-reductase-like1), is a closely related homolog of the rice anther-specific gene OsDFR2 reported previously. Two T-DNA mutants (drl1-1 and drl1-2)(More)
3-Deoxyanthocyanidins are the unique phytoalexins synthesized by sorghum in response to fungal inoculation. They are structurally related to anthocyanins but the final steps of their pathogen-inducible biosynthesis are not fully understood. We have identified new flavonoid structural genes from the recently completed sorghum BTx623 genome sequence. The(More)
Rice is a model system for monocot but the molecular features of rice flavonoid biosynthesis have not been extensively characterized. Rice structural gene homologs encoding chalcone synthase (CHS), chalcone isomerase (CHI), flavanone 3-hydroxylase (F3H), flavonoid 3'-hydroxylase (F3'H), dihydroflavonol 4-reductase (DFR), and anthocyanidin synthase (ANS)(More)
*The bacterial protein YqeH is a circularly permuted GTPase with homologs encoded by plant nuclear genomes. The rice homolog OsNOA1/RIF1 is encoded by the single-copy gene Os02g01440. OsNOA1/RIF1 is expressed in different tissues and is light-inducible. The OsNOA1/RIF1-EYFP fusion protein was targeted to chloroplasts in transgenic Arabidopsis plants. In(More)
Lactoferrin (Mw=78 kDa) is a member of the transferrin family of iron-binding glycoproteins. Previous studies carried out primarily in vitro indicate that the protein has multifunctional properties and may be involved in regulation of iron homeostasis, inhibition of bacterial growth and regulation of immune responses. However, the significance and species(More)
Following inoculation with the anthracnose pathogen Colletotrichum sublineolum, seedlings of the sorghum resistant cultivar SC748-5 showed more rapid and elevated accumulation of luteolin than the susceptible cultivar BTx623. On the other hand, apigenin was the major flavone detected in infected BTx623 seedlings. Luteolin was demonstrated to show stronger(More)
In this study, the authors examine the effects of information systems/technologies (IS/T) on the performance of firms engaged in growth strategies based on mergers and acquisitions (M&A). A model derived from a resource-based theory of the firm is developed to predict the influence of IS/T on performance of firms. Data on the financial performance of 133(More)
C-Glycosylflavones are ubiquitous in the plant kingdom, and many of them have beneficial effects on human health. They are a special group of flavonoid glycosides in which the sugars are C-linked to the flavone skeleton. It has been long presumed that C-glycosylflavones have a different biosynthetic origin from O-glycosylflavonoids. In rice (Oryza sativa),(More)
