Journal ArticleDOI
Auxin and ethylene induce flavonol accumulation through distinct transcriptional networks.
Daniel R. Lewis,Melissa V. Ramirez,Nathan D. Miller,Prashanthi Vallabhaneni,W. Keith Ray,Richard F. Helm,Brenda S.J. Winkel,Gloria K. Muday +7 more
TL;DR: These experiments demonstrate that auxin and ethylene regulate flavonol biosynthesis through distinct signaling networks involving TIR1 and EIN2/ETR1, respectively, both of which converge on MYB12.
Journal ArticleDOI
The Arabidopsis thaliana Myo-Inositol 1-Phosphate Synthase1 Gene Is Required for Myo-inositol Synthesis and Suppression of Cell Death
Janet L. Donahue,Shannon R. Alford,Javad Torabinejad,Rachel E. Kerwin,Aida Nourbakhsh,W. Keith Ray,Marcy Hernick,Xinyi Huang,Blair M. Lyons,Pyae P Hein,Glenda E. Gillaspy +10 more
TL;DR: MIPS1 has a significant impact on myo-inositol levels that is critical for maintaining levels of ascorbic acid, phosphatidyl inositol, and ceramides that regulate growth, development, and cell death.
Journal ArticleDOI
A missing link in the transformation from asymmetric to symmetric metallofullerene cages implies a top-down fullerene formation mechanism
Jianyuan Zhang,Faye L. Bowles,Daniel W. Bearden,W. Keith Ray,Timothy J. Fuhrer,Youqing Ye,Caitlyn Dixon,Kim Harich,Richard F. Helm,Marilyn M. Olmstead,Alan L. Balch,Harry C. Dorn +11 more
TL;DR: It is proposed that the unique asymmetric C1(51383)-C84 cage with destabilizing fused pentagons is a preserved 'missing link' in the top-down mechanism, and in well-established rearrangement steps can form many well-known, high-symmetry fullerene structures that account for the majority of solvent-extractable metallofullerenes.
Journal ArticleDOI
Characterization of a 12-kilodalton rhodanese encoded by glpE of Escherichia coli and its interaction with thioredoxin.
TL;DR: GlpE is the first among the 41 proteins in COG0607 (rhodanese-related sulfurtransferases) of the database Clusters of Orthologous Groups of proteins ( http://www.ncbi.nlm.nih.gov/COG/) for which sulfurtransferase activity has been confirmed.
Journal ArticleDOI
Amylin Amyloid Inhibition by Flavonoid Baicalein: Key Roles of Its Vicinal Dihydroxyl Groups of the Catechol Moiety
TL;DR: Evidence is provided that incubating baicalein and amylin leads to their conjugation, consistent with a Schiff base mechanism, and key roles of the vicinal hydroxyl groups on the A-ring are demonstrated for the first time.
