Summary Potato cells (Solanum tuberosum L.), cultivated in original Murashige-Skoog (MS) medium for 5 days were subsequently transferred into {MS} media containing nitrate or ammonium as sole inorganic N source and incubated under anoxia for 24 h. With regard to lipid stability, these cells behaved differently. Although lipid hydrolysis occurred in both cases by the same mechanism, nitrate was able to postpone free fatty acid release for about 6 h compared with ammonium within the 24 h anoxia treatment. The increased membrane lipid stability of nitrate-treated cells under anoxia was correlated with a higher nitrate reduction capability and an improved energy status.
