Enhanced 3-methoxytyramine levels in crown gall tumours and other undifferentiated plant tissues.
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.
