Abstract Roots of gramineous plants turn deep yellow upon colonization with arbuscular mycorrhizal fungi. At the same time methanolic extracts of maize roots show a polyene absorption with maxima at 375 and 395 nm that is not found in the extracts of controls. After esterification with diazomethane the compound responsible for this absorption was isolated by column chromatography and shown to be all-
摘要 禾本科植物的根在被丛枝菌根真菌定殖后变成深黄色。同时,玉米根的甲醇提取物显示出在 375 和 395 nm 处具有最大值的多烯吸收,这在对照提取物中没有发现。在用重氮甲烷酯化之后,负责该吸收的化合物通过柱色谱分离并且通过NMR和质谱显示为全-E-4,9-二甲基十二-2,4,6,8,10-戊二酸。该化合物可能来自类胡萝卜素的氧化降解。
