To acquire iron, many plant species reduce soil Fe(III) to Fe(II) by Fe(III)-chelate reductases embedded in the plasma membrane of root epidermal cells. The reduced product is then taken up by Fe(II) transporter proteins. These activities are induced under Fe deficiency. We describe here the FRO1 gene from pea (Pisum sativum), which encodes an Fe(III)-chelate reductase. Consistent with this pro...

A new oxyiminopyrazole-based ytterbium chelate enables NIR emission upon UV excitation in colorless single layer luminescent solar concentrators for building integrated photovoltaics.

Low availability of Fe significantly limits crop yields in many parts of the world. However, it is largely unknown which genes and alleles adjust plant growth in Fe limited environments. Using natural variation of a geographically restricted panel of Arabidopsis thaliana accessions, we identify allelic variation at the FRO2 locus associated with root length under iron deficiency. We show that n...

GadoTO, a MR contrast agent for the detection of cell death, consists of a nucleic acid-binding fluorophore attached to a gadolinium chelate.

in order to determine the effects of zinc foliar application on yield and its components single cross 704 under water stress condition, experiment was carried out at agricultural research center of varamin, in southeast of tehran, during 2007-2008. field experiment was conducted in split plot design based on randomized completely block at three replications. main plots included water stress at ...

S ince the initial description in early 2006 (1), a firm epidemiologic link has been established between gadolinium-based contrast (GBC) exposure and development of nephrogenic systemic fibrosis (NSF). When looking back in time, it is interesting to recall that GBC-magnetic resonance imaging (MRI) garnered increased use in patients with kidney disease in the early to mid-1990s based on a percei...

Abstract Segment drying is a severe physiological disorder of citrus fruit, and vesicles become granulated or collapsed. Aside from the hypothesis that alteration cell wall metabolism main factor granulation, little known about vesicle collapse. This study aimed to elucidate changes in pectin during collapse blood orange. Vesicle was characterized by decreased nutrients increased chelate- sodiu...
