To study the effect of brassinosteroids and salinity stress on the fatty acid metabolism in the seeds of oil plants, the authors analyzed the turnover of fatty acids in the seeds of Crambe tatarica under the mentioned conditions. The results of gas-liquid chromatography and mass-spectrometry demonstrated the decrease in the level of palmitic and linoleic fatty acids along with the increase in the level of oleic, eicosenoic, and docosenoic fatty acids in C. tatarica seeds in response to 28-homobrassinolide under salinity stress on some stages of seed germination. These regularities allowed for the assumption that 28-homobrassinolide promotes the stabilization of fatty acid composition of C. tatarica seeds, disrupted under salinity stress. This may indicate the possibility of modulating the activity or expression of desaturase genes and the enzymes of fatty acid oxidation in the anwer on brassinosteroids.

为了研究油菜素类固醇和盐胁迫对油料植物种子脂肪酸代谢的影响，作者分析了在上述条件下海甘蓝种子中脂肪酸的周转情况。气液色谱和质谱分析结果表明，28-高油菜素内酯对鞑靼种子中棕榈酸和亚油酸水平的降低，以及油酸、二十碳烯酸和二十碳烯酸水平的增加进行了分析。种子萌发某些阶段处于盐胁迫下。这些规律允许这样的假设：28-高油菜素内酯促进鞑靼种子的脂肪酸组成的稳定，在盐胁迫下被破坏。这可能表明油菜素类固醇可能调节去饱和酶基因和脂肪酸氧化酶的活性或表达。
