“…The content of phosphatidic acid in the plasma membrane fraction was ca 7 % and was similar in +P and -P roots. A similar amount of PA (5-6 % of total phospholipids) was found by Mansour et al (1994) in the plasma membrane from winter wheat roots. The presence of PA in plant plasma membranes was also reported in roots of soybean (Whitman and Travis 1985), barley (Brown and DuPont 1989) and oat (Norberg and Liljenberg 1991).…”

Plasma membranes were isolated from ro~ts of bean (Phaseolus vulgaris L.) plants cultured on phosphate sufficient or phosphate deficient medium. The phospholipid composition of plasma membranes was analyzed and compared with that of the microsomal fraction. Phosphate deficiency had no influence on lipid/protein ratio in microsomal as well as plasma membrane fraction. In phosphate deficient roots phospholipid content was lower in the plasma membrane, but did not change in the microsomal fraction. Phosphatidylcholine and phosphatidylethanolamine were two major phospholipids in plasmalemma and microsomal membranes (80 % of the total). After two weeks of phosphate starvation a considerable decrease (about 50 %) in phosphatidylcholine and phosphatidylethanolamine in microsomat membranes was observed. The decline in two major phospholipids was accompanied by an increase in phosphatidic acid and lysophosphatidylcholine content. The effect of alterations in plasma membrane phospholipids on membrane fnnction e.g. nitrate uptake is discussed.

“…The membrane lipid composition controls membrane permeability (Grunwald, 1968). Several lines of studies reported that the changes in phospholipid (PL) composition, unsaturation of PL acyl-chains and free sterols of plasma membrane may contribute to the salt tolerance (Brown and Dupont, 1989;Mansour et al, 1994;Wu et al, 1998). Salt stress thus decreased the phosphatidylcholine (PC)/phosphatidylethanolamine (PE) ratio and the proportion of unsaturated fatty acid in PL, and increased free sterol/PL ratio, with consequence of decreased membrane fluidity after all (Mansour et al, 1994;Wu et al, 1998).…”

“…Moreover, the salt itself present in the culture medium, probably plays a deleterious role in regard to the in vitro plant regeneration capacity. Although several researches reported structural damages induced by the salt in plant cells (Mansour et al 1994;Cachorro et al 1995;Koyro 1997;El-Banna and Attia 1999;Mansour and Salama 2004;Yamane et al 2004;Miyake et al 2006;Bruns and Hecht-Bucholz 2007;Bennici and Tani 2009), the informations about the toxic NaCl effects on plant cells cultured in vitro are still very few (Hossain et al 2004;Bennici and Tani 2009).…”

An investigation by electron microscopy has been carried out on Nicotiana tabacum L. var. BELW3 callus cells grown in a medium containing different NaCl concentrations (0.1, 0.2, 0.3 M) for 60 days to study the salt effect at cell level. Control N. tabacum callus exhibited parenchymatous cell types with normal cytoplasm, nucleus, organelles and membranes, together to cells forming meristematic zones by normal mitosis and cytokinesis. The callus cells exposed to the lowest salt dose did not show specific structural changes in comparison to control cells. On the contrary, the callus cells treated with the salt at the highest doses showed alterations of chloroplasts, severe damages at nuclear and cytoplasmic level, until to a complete disorganization of the whole protoplast. Also mitochondria and the membranous system appeared injured. However, in all the salt treated callus cells amylopasts were very abundant. A peculiar phenomenon was the presence in these calli under salt stress of cells contiguous to the damaged or dead cells which appeared normal in their structure. This fact confirmed the possibility to regenerate plants from callus under salt treatment in view to obtain salt tolerant crops.
