Fecal microbial determinants of fecal and systemic estrogens and estrogen metabolites: a cross-sectional study

Journal of Translational Medicine, 2012
Background High systemic estrogen levels contribute to breast cancer risk for postmenopausal women, whereas low levels contribute to osteoporosis risk. Except for obesity, determinants of non-ovarian systemic estrogen levels are undefined.

Development of the HTRF assay to evaluate the auxin‐induced binding between TIR1 and IAA7

New Phytologist, EarlyView.
Summary Auxin plays diverse roles in plant growth and development, including sensing environmental changes. Quantifying the interaction between auxin coreceptors provides the molecular basis for cells to sense and adapt to environmental cues. Although several assays are available, a more high‐throughput method is necessary to efficiently evaluate the ...

Application of sonication-assisted Agrobacterium-mediated transformation in Chenopodium rubrum L

Plant, Soil and Environment, 2003
Chenopodium rubrum belongs to the plant species in which standard Agrobacterium-mediated transformation procedures remain inefficient. We demonstrate that the employment of sonication-assisted Agrobacterium-mediated transformation (SAAT) effectively ...

Engineering of the Flavone Rutinoside Biosynthetic Pathway Enables Production of Diosmin, a Venoactive Compound in Solanum lycopersicum and Nicotiana tabacum

Plant Biotechnology Journal, EarlyView.
ABSTRACT Diosmin is often used as a dietary supplement, and it is sometimes used to make phlebotropic drugs for venous diseases. Traditionally, diosmin is obtained by the dehydrogenation of the flavanone glycoside hesperidin through chemical semisynthesis.

Phage Display Derived Antibodies Against Antimicrobial Peptide FsPDF2 Reveal Stress Response in European Beech

Plant Biotechnology Journal, EarlyView.
ABSTRACT Plant defensins (PDFs) are cysteine‐rich antimicrobial peptides (AMPs) that are important components of plant immunity. They occur constitutively in various plant tissues but are also upregulated upon stress. Therefore, these molecules are of great interest as markers for the diagnosis of early forest stress response in plants at the molecular

Remote Sensing of Endogenous Pigmentation by Inducible Synthetic Circuits in Grasses

Plant Biotechnology Journal, EarlyView.
ABSTRACT Plant synthetic biology holds great promise for engineering plants to meet future demands. Genetic circuits are being designed, built and tested in plants to demonstrate the proof of concept. However, developing these components in monocots, which the world relies on for grain, lags behind dicot models, such as Arabidopsis thaliana and ...
