The ultrastructure and symplastic transport function of Ectodesmata-like (ED-like) of the root cap cells of Zea mays, during the detaching stage, were reported by using fluorescence and electron microscopy. It was described the process that plasmodesmata (PD) were gradually stretched and changed
The major detoxification product in maize roots after 24 h benzoxazolin-2(3H)-one (BOA) exposure was identified as glucoside carbamate resulting from rearrangement of BOA-N-glucoside, but the pathway of N-glucosylation, enzymes involved and the site of synthesis were previously unknown. Assaying
Purified phosphoenolpyruvate carboxylase from both the crassulacean acid metabolism plant Crassula argentea and the C4 plant Zea mays was shown by kinetic studies at saturating fixed-varying concentrations of free mg2+ to selectively use the metal-complexed form of phosphoenolpyruvate when assayed
Three dicarbonyl reagents were used to demonstrate the presence of an essential arginine residue in the NO(3) (-) uptake system from corn seedling roots (Zea mays L., Golden Cross Bantam). Incubation of corn seedlings with 2,3-butanedione (0.125-1.0 millimolar) and 1,2-cyclohexanedione (0.5-4.0
Myosin has been localized to plasmodesmata in root tissues of Allium cepa, Zea mays and Hordeum vulgare using a polyclonal antibody to animal myosin in both fluorescence and electron microscopy. Labelling was also observed throughout the cytoplasm, mainly associated with the endoplasmic reticulum
