II Changes in plasmalemma permeability and its relation with membrane lipid peroxidation in leaves under salt stress.
Roots possess a significant cation-exchange capacity, due largely to the presence of carboxyl groups, which may be involved in moving ions through the outer part of the root to the plasmalemma, where active absorption takes place.
The antioxidant defense, as determined by the overproduction of SOD, was stronger at the plasmalemma than at PSII.
Expression of the transgenic FeSOD protected both the plasmalemma and photosystem II against superoxide generated during illumination of leaf discs containing MV.
According to Krjatchenko (1925), in Lilium croceum "une substance graisseuse" (a granular substance) is formed at tetrad stage by the mitochondria of the tapetal cells and is excreted through the plasmalemma to form a dented locule surface.
1969) observed endoplasmic reticulum elements, dispersed through the cytoplasm from the nuclear membrane to areas in the vicinity of the plasmalemma, producing electron-dense bodies with characteristics similar to those of the central core of the sporopollenin granules.
In few papers on the subject, pro-orbicules were believed to appear between the tapetal plasmalemma and the degenerating walls of the tapetal cells (Homer & Lersten, 1971; Christensen et al.
The next question, then, is how they pass the tapetal plasmalemma.
The plasmalemma membrane, however, is maintained next to the cell wall and prevents uncontrolled leakage of the cell fluids into the intercellular spaces.
In these cases it has been argued that localized pH changes may occur at the inner surface of the plasmalemma especially if the result of added auxin is directed cell elongation (Kurkjian & Guern, 1989).
