TL;DR: A series of broad-host-range expression and lac fusion vectors, based on RSF1010 derivatives, was constructed, allowing the identification and characterization of promoter-carrying cloned fragments on the translational level, whereas the transcriptional fusion vectors can be used to identify and to study promoters on cloned fragment.

TL;DR: The results clearly demonstrate a differential influence of MYB11, MYB12 and MYB111 on the spatial accumulation of specific flavonol derivatives in leaves, stems, inflorescences, siliques and roots and evidence that a separate Flavonol control mechanism might be at play in pollen is presented.
Abstract: The flavonol branch of flavonoid biosynthesis is under transcriptional control of the R2R3-MYBs production of flavonol glycoside1 (PFG1/MYB12, PFG2/MYB11 and PFG3/MYB111) in Arabidopsis thaliana. Here, we investigated the influence of specific PFG transcription factors on flavonol distribution in various organs. A combination of genetic and metabolite analysis was used to identify transcription factor gene-metabolite correlations of the flavonol metabolic pathway. Flavonol glycoside accumulation patterns have been analysed in wild-type and multiple R2R3-MYB PFG mutants in an organ- and development-dependent manner using high-performance thin-layer chromatography, supplemented with liquid chromatography-mass spectroscopy metabolite profiling. Our results clearly demonstrate a differential influence of MYB11, MYB12 and MYB111 on the spatial accumulation of specific flavonol derivatives in leaves, stems, inflorescences, siliques and roots. In addition, MYB11-, MYB12- and MYB111-independent flavonol glycoside accumulation was observed in pollen grains and siliques/seeds. The highly complex tissue- and developmental-specific regulation of flavonol biosynthesis in A. thaliana is orchestrated by at least four PFG transcription factors, differentially influencing the spatial accumulation of specific flavonol derivatives. We present evidence that a separate flavonol control mechanism might be at play in pollen.

TL;DR: In this article, the background-field Green functions are shown to possess very desirable theoretical properties and a consistent on-shell renormalization procedure retaining the full gauge symmetry is presented.
