author keywords: Arabidopsis thaliana; Anthocyanin biosynthesis; Production of anthocyanin pigmentation 1; Nitrogen

MeSH headings : Anthocyanins / biosynthesis; Arabidopsis / cytology; Arabidopsis / genetics; Arabidopsis / metabolism; Arabidopsis Proteins / metabolism; Basic Helix-Loop-Helix Transcription Factors / metabolism; Biosynthetic Pathways; Gene Expression Regulation, Plant; Genes, Plant; Genetic Variation; Genotype; Nitrogen / metabolism; Pancreatitis-Associated Proteins; Transcription Factors / metabolism

TL;DR: Nitrogen regulation of anthocyanin biosynthesis in red cells undergoes a mechanism by which nitrogen controls the expression of genes encoding both main components of the TTG1–GL3/TT8–PAP1 complex and negative regulators. (via Semantic Scholar)

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)

author keywords: Cornus canadensis; Organogenesis; Regeneration; Rhizomes; Tissue culture

TL;DR: An efficient regeneration system is reported for a dwarf dogwood species C. canadensis through organogenesis from rejuvenated leaves, which facilitates developing a genetic transformation system to test candidate genes involved in the developmental divergence of inflorescences in Cornus.

author keywords: Anthocyanin; Callus; HPLC-mass spectrum; Metabolic profiling; Nicotiana tabacum; PAP1; Tobacco; Transgene

MeSH headings : 2,4-Dichlorophenoxyacetic Acid / pharmacology; Anthocyanins / biosynthesis; Anthocyanins / chemistry; Arabidopsis / drug effects; Arabidopsis / metabolism; Arabidopsis / radiation effects; Arabidopsis Proteins; Chromatography, High Pressure Liquid; Chromatography, Liquid; Indoleacetic Acids / pharmacology; Light; Mass Spectrometry; Nitrates / pharmacology; Pancreatitis-Associated Proteins; Plants, Genetically Modified; Potassium Compounds / pharmacology; Tissue Culture Techniques; Tobacco / cytology; Tobacco / drug effects; Tobacco / genetics; Tobacco / growth & development; Transcription Factors / metabolism

TL;DR: It is demonstrated that dark, nitrogen nutrients, and auxin apparently affect the anthocyanin profiles in PAP1 transgenic callus cultures; and it is suggested that these cell cultures are an appropriate system to study the regulatory function of P AP1 on the anthOCyanin biosynthesis at post-transcriptional level in vivo.
