Arabidopsis boron transporter for xylem loading
Boron deficiency hampers the productivity of 132 crops in more than 80 countries. Boron is essential in higher plants primarily for maintaining the integrity of cell walls and is also beneficial andExpand

Selenate-resistant mutants of Arabidopsis thaliana identify Sultr1;2, a sulfate transporter required for efficient transport of sulfate into roots.
To investigate how plants acquire and assimilate sulfur from their environment, we isolated and characterized two mutants of Arabidopsis thaliana deficient in sulfate transport. The mutants areExpand

Fractionation of nitrogen isotopes by glutamine synthetase isolated from spinach leaves
The isotopic fractionation of nitrogen in the reaction in vitro of glutamine synthetase isolated from spinach leaves was calculated from the changes in natural 15 N abundance of ammonia and amide ofExpand

Identification of Zn-nicotianamine and Fe-2'-Deoxymugineic acid in the phloem sap from rice plants (Oryza sativa L.).
In higher plants, the supply of metals such as Zn and Fe via phloem is important for the growth and physiology of young organs. However, little information is available on the speciation (chemicalExpand

Nano scale proteomics revealed the presence of regulatory proteins including three FT-Like proteins in phloem and xylem saps from rice.
The main physiological roles of phloem and xylem in higher plants involve the transport of water, nutrients and metabolites. They are also involved, however, in whole plant events including stressExpand

Detection of nifH Sequences in Sugarcane (Saccharum officinarum L.) and Pineapple (Ananas comosus [L.] Merr.)
To detect N2-fixing bacteria in a plant without using culture methods, nifH gene segments were amplified with degenerate primers from DNA extracted from stems of sugarcane (Saccharum officinarum L.)Expand

Route and Regulation of Zinc, Cadmium, and Iron Transport in Rice Plants (Oryza sativa L.) during Vegetative Growth and Grain Filling: Metal Transporters, Metal Speciation, Grain Cd Reduction and Zn
Zinc (Zn) and iron (Fe) are essential but are sometimes deficient in humans, while cadmium (Cd) is toxic if it accumulates in the liver and kidneys at high levels. All three are contained in theExpand

Regulation of sulfur-responsive gene expression by exogenously applied cytokinins in Arabidopsis thaliana.
Effects of plant hormones on a sulfur-deficiency responsive element (betaSR) from the promoter region of the beta subunit gene of beta-conglycinin, a major seed storage protein of soybean, wereExpand

Effects of pH and Osmotic Stress on Cellular Polyamine Contents in the Soybean Rhizobia Rhizobium fredii P220 and Bradyrhizobium japonicum A1017.
Homospermidine is a polyamine present in its highest concentrations in root nodule bacteria. By using the soybean rhizobia Rhizobium fredii P220 and Bradyrhizobium japonicum A1017, the effects of theExpand

Starch-Related α-Glucan/Water Dikinase Is Involved in the Cold-Induced Development of Freezing Tolerance in Arabidopsis1
Cold-induced soluble sugar accumulation enhances the degree of freezing tolerance in various cold-hardy plants including Arabidopsis (Arabidopsis thaliana), where soluble sugars accumulate in only aExpand
