Characterization of development and artemisinin biosynthesis in self-pollinated Artemisia annua plants

PLANTA, 234(4), 685–697.

By: F. Alejos-Gonzalez n, G. Qu n, L. Zhou n, C. Saravitz n, J. Shurtleff n & D. Xie n 

author keywords: Artemisinin; Artemisia annua; HPLC-MS; Metabolic profiling; Self-pollination; Genetic engineering
MeSH headings : Alkyl and Aryl Transferases / genetics; Antimalarials / isolation & purification; Antimalarials / metabolism; Artemisia annua / anatomy & histology; Artemisia annua / chemistry; Artemisia annua / enzymology; Artemisia annua / physiology; Artemisinins / isolation & purification; Artemisinins / metabolism; Chromatography, High Pressure Liquid; Cytochrome P-450 Enzyme System / genetics; Flowers / anatomy & histology; Flowers / chemistry; Flowers / enzymology; Flowers / physiology; Lactones / isolation & purification; Lactones / metabolism; Plant Leaves / anatomy & histology; Plant Leaves / chemistry; Plant Leaves / enzymology; Plant Leaves / physiology; Plant Proteins / genetics; Plants, Medicinal; Pollination / physiology; Seedlings / anatomy & histology; Seedlings / chemistry; Seedlings / enzymology; Seedlings / physiology; Self-Fertilization / physiology; Spectrometry, Mass, Electrospray Ionization; Time Factors
TL;DR: High performance liquid chromatography–mass spectrometry-based metabolic profiling analyses showed that leaves, flowers, and young seedlings of F2 plants produced artemisinin, and RT-PCR analysis showed that progeny of self-pollinated plants expressed the amorpha-4, 11-diene synthase (ADS) and cytochrome P450 monooxygenase 71 AV1 (CYP71AV1) genes, which are involved in art Artemisia annua (via Semantic Scholar)

Signature amino acids enable the archaeal L7Ae box C/D RNP core protein to recognize and bind the K-loop RNA motif

RNA, 16(1), 79–90.

By: K. Gagnon n, X. Zhang n, G. Qu n, S. Biswas n, J. Suryadi *, B. Brown n, E. Maxwell n

author keywords: box C/D snoRNA; snoRNP; kink-turn; L7Ae/L30 proteins; RNA-protein interaction
MeSH headings : Amino Acid Motifs / physiology; Amino Acid Sequence; Archaea / genetics; Archaea / metabolism; Archaeal Proteins / chemistry; Archaeal Proteins / genetics; Archaeal Proteins / metabolism; Base Sequence; Binding Sites / genetics; Conserved Sequence; Models, Biological; Models, Molecular; Molecular Sequence Data; Mutagenesis, Site-Directed; Nucleic Acid Conformation; Protein Binding / genetics; RNA, Archaeal / chemistry; RNA, Archaeal / metabolism; Ribonucleoproteins / chemistry; Ribonucleoproteins / genetics; Ribonucleoproteins / metabolism; Sequence Homology, Amino Acid
TL;DR: These five signature amino acids are distinct for each of the L7Ae/L30 family members, suggesting an evolutionary continuum of these RNA-binding proteins for recognition of the various K-turn motifs contained in their cognate RNAs. (via Semantic Scholar)
