Regulation of Cytokinin Oxidase Activity in Callus Tissues of Phaseolus vulgaris L. cv Great Northern.

abstract：:Two isoforms of fructose 1,6-bisphosphatase are present in the green alga Selenastrum minutum. The isoenzymes can be separated with ionexchange chromatography or acid precipitation. The stability of the two isoenzymes differ largely. The acid insoluble enzyme exhibits properties similar to that of the enzyme from the ...
