Electrophoretic variation and inheritance of four novel enzyme systems were studied in maize (Zea mays L.). A minimum of 10 genetic loci collectively encodes isozymes of aconitate hydratase (ACO; EC 4.2.1.3.), adenylate kinase (ADK; EC 2.7.4.3), NADH dehydrogenase (DIA; EC 1.6.99.-), and shikimate
Adenylate kinase (EC 2.7.4.3) from leaves of maize (Zea mays) was purified to homogeneity using (NH(4))(2)SO(4) fractionation, followed by chromatography on DEAE-cellulose, hydroxyapatite, Sephadex G-75SF, and Green A dye-ligand columns. The purified enzyme had specific activity of about 1,550
Corn plants (Zea mays L. cv Pioneer 3906) were grown in a glass house on control and saline nutrient solutions, in winter and summer. There were two saline treatments, both with osmotic potential = -0.4 megapascal but with different Ca(2+)/Na(+) ratios: 0.03 and 0.73. Root tips and shoot meristems
Recently, a nonaqueous fractionation method of obtaining highly purified mesophyll chloroplasts from maize leaves was established. This method is now used to determine adenine nucleotide levels, the redox states of the NADP system, Pi levels and dihydroxyacetone phosphate/3-phosphoglycerate ratios
