Regulation of Cytoplasmic and Vacuolar pH in Maize Root Tips under Different Experimental Conditions.
(31)P-Nuclear magnetic resonance spectra of perfused maize (Zea mays L., hybrid WW x Br 38) root tips, obtained at 10-minute intervals over 12 hours or longer, indicate that no cytoplasmic or vacuolar pH changes occur in these cells in the presence of 25 millimolar K(2)SO(4), which induces extrusion of 4 to 5 microequivalents H(+) per gram per hour. In contrast, hypoxia causes cytoplasmic acidi...
متن کاملMechanisms of cytoplasmic pH regulation in hypoxic maize root tips and its role in survival under hypoxia.
We show that a transient lactic fermentation provides the signal triggering ethanol production in hypoxic maize root tips. The signal is cytoplasmic pH. This interaction between lactic and ethanolic fermentation permits tight cytoplasmic pH regulation during hypoxia--cytoplasmic pH remaining near neutrality for several hours. Mutant roots unable to synthesize ethanol can neither regulate cytopl...
متن کاملYield and nitrogen leaching in maize field under different nitrogen rates and partial root drying irrigation
Irrigation water is limiting for crop production in arid and semi-arid areas. Furthermore, excess nitrogen (N) application is a source of groundwater contamination. Partial root drying irrigation (PRD) can be used as water saving technique and a controlling measure of groundwater N contamination. The objectives of this investigation were to evaluate the effect of ordinary furrow irrigation (OFI...
متن کاملMeasurement of intracellular pH in maize root tissue with a-methyl fluorinated alanines and in-vivo F NMR spectroscopy
Methods for the simultaneous measurement of vacuolar and cytoplasmic pH in plant tissues currently have significant limitations. This study demonstrates the usefulness of methyl difluoro alanine (F2ALA) and methyl trifluoro alanine (F3ALA) with in-vivo F NMR spectroscopy to measure vacuolar and cytoplasmic pH in maize root tissue. The pH dependence of the chemical shift of F2ALA and F3ALA is gr...
متن کاملH Efflux and Hexose Transport under Imposed Energy Status in Maize Root Tips.
The relationship between changes in H(+) flux and sugar transport in maize Zea mays L. DEA root tips have been investigated using two methods for controlling the cellular nucleotide level: (a) incubation in the presence of a glucose analog, the 2-deoxyglucose, which decreased the ATP level to less than 15% of its initial value within 60 minutes without changing the ADP and AMP levels; (b) an hy...
