The ultrastructure of etioplasts and the acyl lipid and the fatty acid composition of sequential 2-centimeter sections cut from the base (youngest) to the top (oldest) of nonilluminated 5-day-old etiolated leaves of Zea mays L., and the acyl lipid and fatty acid composition of the etioplasts
Dark response genes: a group of endogenous pendulum/timing players in maize?

Main conclusion: Maize has a set of dark response genes, expression of which is influenced by multiple factor and varies with maize inbred lines but without germplasm specificity. The response to photoperiod is a common biological issue across the species kingdoms.

Five-or six-day old seedlings of corn (Zea mays L.) were exposed to 0.25 mm Ca(NO(3))(2), 1.0 mm sodium 2-[N-morpholino]-ethanesulfonate, 5 mug Mo per liter and 50 mug of chloramphenicol per ml at pH 6. Nitrate uptake was determined from depletion of the ambient solution. The pattern of nitrate
Reactivation of phloem export in mature maize leaves after a dark period.

Mature leaves of corn plants (Zea mays L. cv. Prior) which were darkened for 48 h contain neither bundle-sheath starch nor glucose, and their sucrose content is below 5 μM. In such leaves phloem export has ceased. When re-illuminated, photosynthetic sucrose production starts without delay, but the
The effect of oxygen on nitrate and nitrite assimilation in leaves of Zea mays L. under dark conditions.

The assimilation of nitrate under dark-N2 and dark-O2 conditions in Zea mays leaf tissue was investigated using colourimetric and (15)N techniques for the determination of organic and inorganic nitrogen. Studies using (15)N indicated that nitrate was assimilated under dark conditions. However, the
Carbon Isotopic Fractionation Does Not Occur during Dark Respiration in C3 and C4 Plants.

The magnitude of possible carbon isotopic fractionation during dark respiration was investigated with isolated mesophyll cells from mature leaves of common bean (Phaseolus vulgaris L.), a C3 plant, and corn (Zea mays L.), a C4 plant. Mesophyll protoplasts were extracted from greenhouse-grown leaves
Dark/Light modulation of ribulose bisphosphate carboxylase activity in plants from different photosynthetic categories.

Ribulose bisphosphate carboxylase/oxygenase (RuBPCase) from several plants had substantially greater activity in extracts from lightexposed leaves than dark leaves, even when the extracts were incubated in vitro with saturating HCO(3) (-) and Mg(2+) concentrations. This occurred in Glycine max,
Changes in Sensitivity to Effectors of Maize Leaf Phosphoenolypyruvate Carboxylase during Light/Dark Transitions.

Illumination of previously darkened maize (Zea mays L. cv Golden Cross Bantam T51) leaves had no effect on the concentration of phosphoenolpyruvate (PEP) carboxylase protein, but increased enzyme activity about 2-fold when assayed under suboptimal conditions (pH 7.0 and limiting PEP). In addition,
Induction of a carbon-starvation-related proteolysis in whole maize plants submitted to Light/Dark cycles and to extended darkness

Three-week-old maize (Zea mays L.) plants were submitted to light/dark cycles and to prolonged darkness to investigate the occurrence of sugar-limitation effects in different parts of the whole plant. Soluble sugars fluctuated with light/dark cycles and dropped sharply during extended darkness.
Light-harvesting complex II is an antenna of photosystem I in dark-adapted plants

Photosystem I (PSI) is a major player in the light reactions of photosynthesis. In higher plants, it consists of a core complex and four external antennae, Lhca1-4 forming the PSI-light-harvesting complex I (LHCI) supercomplex. The protein and pigment composition as well as the spectroscopic

Irradiation of maize (Zea mays) roots and coleoptiles with visible light causes dark-reversible absorbance changes in these organs. There is an increase in absorbance near 440 nanometers and smaller increases below 410 nanometers and about 595 nanometers. Decreases in absorbance are observed at

A growing body of evidence suggests that plant root-associated fungi such as dark septate endophytes (DSE) can help plants overcome many biotic and abiotic stresses, of great interest is DSE-plant metal tolerance and alleviation capabilities on contaminated soils. However, the tolerance and

The constriction of pupil dilation following dark adaptation was studied as a potentially useful biological monitor of systemic exposure to organophosphorus pesticides (OPs). Pupil dilation and blood cholinesterase levels were monitored in 4 cynomolgus monkeys following oral administration of 2.0

Nitrate reductase can be induced in excised shoots of 3-day-old dark-grown Zea mays (var. WF9 x M14) seedlings in the absence of light. In contrast, leaves of 10-day-old dark-grown seedlings require a light treatment in order to induce enzymatic activity. Leaves of 10-day-old dark-grown seedlings
