In this research, leaf area prediction model was developed for some leaf-used maize (Zea mays L.) cultivars namely Coluna, Luce, Maveric, Ranchero, TTM-813, Zamora and RX-788 grown in Black Sea region of Turkey. Lamina width, length and leaf area were measured without destroying the leaf to develop the models. The actual leaf areas of the plants were measured by PLACOM Digital Planimeter and mu...
Siderophore facilitates iron availability in soil, but its assistance in iron transportation to different plant parts is not reported till date. Therefore, it is worthwhile to study the effect of siderophore produced by Pseudomonas for iron acquisition in the presence and absence of iron. To study these effects, two siderophore-producing Pseudomonas aeruginosa strains RSP5 and RSP8 were selecte...
Rates of CO(2) assimilation and leaf conductances to CO(2) transfer were measured in plants of Zea mays during a period of 14 days in which the plants were not rewatered, and leaf water potential decreased from -0.5 to -8.0 bar. At any given ambient partial pressure of CO(2), water stress reduced rate of assimilation and leaf conductance similarly, so that intercellular partial pressure of CO(2...
A nonaqueous fractionation method to obtain highly purified mesophyll chloroplasts from lyophilized leaves of Zea mays L. is described. The levels of several metabolites including pyruvate were determined in the purified mesophyll chloroplast fractions which were prepared from leaves exposed to different light intensities. The role of pyruvate in the regulation of pyruvate,Pi dikinase in these ...
Lysine-ketoglutarate reductase activity was detected and characterized in the developing endosperm of maize (Zea mays L.). The enzyme showed specificity for its substrates: lysine, alpha-ketoglutarate, and NADPH. Formation of the reaction product saccharopine was demonstrated. The pH optimum of the enzyme was close to 7, and the K(m) for lysine and alpha-ketoglutarate were 5.2 and 1.8 millimola...
In the range 16 to 29 degrees C, increases in temperature caused large (two-to threefold) increases in growth velocity, growth strain rate, and biomass deposition rate in primary roots of maize, Zea mays L. Temperature had small effects on root diameter, fresh weight density, and dry weight density, and negligible effects on length of the growth zone and growth strain at particular positions.
Intact chloroplasts of spinach (Spinacia oleracea L.), sunflower (Helianthus annuus L.), and maize (Zea mays L.) mesophyll cells contained 0.33, 0.50, and 0.14% of bound hexosamine on a protein basis, respectively. Undifferentiated maize chloroplasts contained 0.19%. Values for chloroplast lamellae were, respectively, 0.16, 0.18, 0.12, and 0.06% and for envelope membranes they were 1.6, 2.5, 3....
A new form of fructokinase has been identified from developing maize (Zea mays L.) kernels that utilizes CTP, UTP, and GTP from four to eight times more effectively than ATP at nonlimiting concentrations. Ten millimolar dithiothreitol was necessary to stabilize activity. A second form of fructokinase was nonspecific for nucleoside triphosphate whereas a third form was fairly specific for ATP.
Purification and characterization of cytosolic 6-phosphogluconate dehydrogenase isozymes from maize.
Cytosolic isozymes of 6-phosphogluconate dehydrogenase were purified from roots of maize (Zea mays L.). The final preparation contained two 55-kD proteins. Affinity-purified dehydrogenases from a maize line that is null for both cytosolic 6-phosphogluconate dehydrogenase isozymes (Pgd1-null, Pgd2-null) lacked the 55-kD proteins. The substrate kinetics of the purified enzyme were determined.
BACKGROUND Zea mays L. (Z. mays) has been used for human consumption in the various forms of meal, cooking oil, thickener in sauces and puddings, sweetener in processed food and beverage products, bio-disel. However, especially, in case of husk extract of Z. mays, little is known about its anti-inflammatory effects. Therefore, in this study, the anti-inflammatory effects of Z. mays husk extract...
