Eicosapentaenoic and arachidonic acids extracted from the fungus Phytophthora infestans elicit the accumulation of fungitoxic sesquiterpenoid stress metabolites and inhibit the accumulation of steroid glycoalkaloids in potato tubers. This dual activity, which did not occur with other saturated and unsaturated fatty acids tested, corresponds to the activity of incompatible races of Phytophthora infestans and crude elicitor preparations from Phytophthora infestans that contain bound forms eicosapentaenoic and arachidonic acids. Arachidonic acid applied to potato slices, which had been aged for various time intervals, elicited the accumulation of sesquiterpenoid stress metabolites and concomitantly inhibited the accumulation of steroid glycoalkaloids.
从真菌 Phytophthora infestans 中提取的二十碳五烯酸和花生四烯酸会引发真菌毒性倍半萜应激代谢物的积累，并抑制马铃薯块茎中甾体糖苷生物碱的积累。这种双重活性不会出现在其他测试的饱和和不饱和脂肪酸中，与不亲和的 Phytophthora infestans 菌株以及含有结合形式的二十碳五烯酸和花生四烯酸的 Phytophthora infestans 粗诱导剂制剂的活性相对应。将花生四烯酸施加到已老化不同时间间隔的马铃薯切片上，会引发倍半萜应激代谢物的积累，并同时抑制甾体糖苷生物碱的积累。
