Popis: | The qualitative and quantitative influence of 3mM phosphonate on the lipid classes and component fatty acids was studied in Phytophthora capsici . The treatment increased the phospholipid content of the mycelium while the concentration of neutral lipids, and particularly TAG, was lowered. The distribution of fatty acids in neutral and polar lipids was affected: the proportion of saturated C16, C18 and polyunsaturated 18:3 n -6 increased; on the contrary, the polyunsaturated C20 fatty acids concentration decreased suggesting alterations of the fatty acid desaturation processes. The minor alternate pathway leading to a biosynthesis of 20:5 n -3, observed after addition of labelled 18:3 n -3, was totally inhibited after phosphonate treatment. |
