Abstract
An amine, after dansylation, has been isolated from Nicotiana tabacum crown gall tumours for the first time and characterized as 4-hydroxy-3-methoxy-beta-phenylethylamine (3-methoxytyramine). The compound cannot be detected in differentiated N. tabacum tissues but appears in the corresponding callus controls. Its concentration is further increased 5-42-fold when N. tabacum is transformed with all strains of Agrobacterium tumefaciens so far tested.
摘要
首次从烟草冠瘿瘤中分离出一种经丹磺酰化的胺，并将其鉴定为4-羟基-3-甲氧基-β-苯乙胺（3-甲氧基酪胺）。在分化的烟草组织中未检测到该化合物，但在相应的愈伤组织对照中出现。当用迄今为止测试的所有根癌农杆菌菌株转化烟草时，其浓度进一步增加5至42倍。
