aconitase/zea mays

The maize (Zea mays L.) stem pulvinus is a disc of tissue located apical to each node that functions to return a tipped stem to a more upright position via increased cell elongation on its lower side. We investigated the possibility that reactive oxygen species (ROS) and hydrogen peroxide (H2O2), in

Regulation of expression and methylation of promoters of two aconitase (EC 4.2.1.3) genes by light have been investigated in maize (Zea mays L.) in relation to the involvement of phytochrome. Transferring of plants from light to darkness resulted in the stimulation of aconitase activity in

Aconitase (EC 4.2.1.3) catalyzes the reversible interconversion of citrate, cis-aconitate, and D-isocitrate. It operates in mitochondria and cytosol. We investigated the expression of two aconitase genes (Aco1 and Aco4) and activities of the mitochondrial and cytosolic forms in maize (Zea mays L.)

The influence of aging on susceptibility to environmental contaminants is not well understood. To extend knowledge in this area, we examined effects in rat brain of the volatile organic compound, toluene. The objective was to test whether oxidative stress (OS) plays a role in the adverse effects

2,3,7,8-Tetrachlorodibenzo-p-dioxin (dioxin; TCDD) is a pervasive environmental contaminant that induces hepatic and extrahepatic oxidative stress. We have previously shown that dioxin increases mitochondrial respiration-dependent reactive oxygen production. In the present study we examined the
