Influence of phenolic acids on ion uptake: I. Inhibition of phosphate uptake.

abstract：:A new bacterial agglutinin was isolated from seeds of the soybean cultivar Clark. Purification was carried out by ammonium sulfate precipitation and ion-exchange chromatography. The agglutinin is a heat-labile glycoprotein most active at pH 4.0. Addition of Ca(2+), Mn(2+) and Mg(2+) did not enhance the agglutinating a...

abstract：:alpha-Amylases are important enzymes for starch degradation in plants. However, it has been a long-running debate as to whether alpha-amylases are localized in plastids where starch is stored. To study the subcellular localization of alpha-amylases in plant cells, a rice (Oryza sativa) alpha-amylase, alphaAmy3, with o...
