The Arabidopsis NPF7.2 mediates coumarin uptake for root iron acquisition

New Phytologist, EarlyView.
Summary Iron (Fe) is a transition metal necessary for achieving essential physiological processes throughout the plant lifecycle. In Arabidopsis thaliana, secreting Fe‐mobilizing coumarins (FMC) is a key mechanism enabling roots to acquire nonbioavailable Fe present in soils.

Ab initio analysis of the x-ray absorption spectrum of the myoglobin-carbon monoxide complex: Structure and vibrations

, 2010
We present a comparison between Fe K-edge x-ray absorption spectra of carbonmonoxy-myoglobin and its simulation based on density-functional theory determination of the structure and vibrations and spectral simulation with multiple-scattering theory.

A Complete Expression Profile of Matrix-Degrading Metalloproteinases in Dupuytren’s Disease [PDF]

, 2007
Dupuytren’s disease (DD) is a common fibrotic condition of the palmar fascia, leading to deposition of collagen-rich cords and finger contractions. The metzincin superfamily contains key enzymes in the turnover of collagen and other extracellular matrix ...

Novel roles of sulfur metabolism in stress‐controlled stomata aperture regulation

New Phytologist, EarlyView.
Summary Stomatal closure allows plants to conserve water by reducing transpiration during drought. Surprisingly, the assimilation of the macronutrient sulfur is intimately connected to the drought stress response. This Tansley insight will only briefly touch on the general impact of sulfate assimilation on the production of drought‐response metabolites.

Green Tea Polyphenol Epigallocatechin Gallate Interactions with Copper-Serum Albumin

Molecules
Epigallocatechin gallate (EGCg), an abundant phytochemical in green tea, is an antioxidant that also binds proteins and complex metals. After gastrointestinal absorption, EGCg binds to serum albumin in the hydrophobic pocket between domains IIA and IIIA ...

Increased expression of matrix metalloproteinase-9 in patients with temporal lobe epilepsy [PDF]

, 2014
Aim: The molecular mechanism of epileptogenesis in temporal lobe epilepsy is still unclear. Experimental studies have suggested that matrix metalloproteinases have important roles in this process, but human studies are limited.

OsbHLH064, an IVb bHLH Transcription Factor, Regulates Iron Homeostasis and Enhances Grain Fe Accumulation in Rice

Plant Biotechnology Journal, EarlyView.
ABSTRACT Iron (Fe) is an essential micronutrient for plant growth and development. The maintenance of Fe homeostasis relies on sophisticated regulatory networks where bHLH transcription factors play a key role. However, how these factors coordinate to regulate this vital process is not fully understood.
