Salt-induced lipid changes in Catharanthus roseus cultured cell suspensions

Propiconazole Toxicity on the Non-Target Organism, the Arbuscular Mycorrhizal Fungus, Glomus irregulare

“…Moreover, in presence of propiconazole at 2 mg.L -1 , PLFA analysis highlighted significant increases in the total quantity due mainly to C16:0, C18:0 and C18:3 increases. Similar disturbances in PL and in PLFA quantities were also described in plant under salinity stress (Parti et al, 2003;Elkahoui et al, 2004). Parti et al (2003) explained these lipid changes by mean of adaptations which increase the ability of the plant to endure salinity.…”

Calcium can moderate changes on membrane structure and lipid composition in cowpea plants under salt stress

“…These stressing factors can disturb biochemical and physiological processes such as water relations, ionic and redox homeostasis, hormonal and nutritional balance, and membrane permeability, which may result in reduced growth (Parida and Das 2005). In plants, changes in lipid bilayer composition and membrane permeability due to salt stress were reported by various authors (Kerkeb et al 2001;Elkahoui et al 2004;Lopéz-Pérez et al 2009). Such modifications of the lipid bilayer result in alterations of membrane fluidity and H ?…”

Rapid neutral lipid accumulation of the alkali-resistant oleaginous Monoraphidium dybowskii LB50 by NaCl induction

“…However, at 60 g L À1 NaCl induction, the change in PL was similar to that in N. laevis. PL is the main component of membrane lipids, and PL accumulation could stimulate membrane biosynthesis (Elkahoui et al, 2004). Microalgae synthesized more PL by reducing membrane fluidity and permeability to help algae adapt to salt stress at higher salt concentrations.…”
