Results show the feasibility of regenerating rooting Bidens alba plants from nopaline-type crown galls incited by Agrobacterium tumefaciens containing pTi-T37. Transmission of the tumour marker nopaline synthesis is demonstrated into the fourth generation but decreases in level of expression or loss of the trait occurs. Nopaline synthesis and auxin autotrophy, as markers, can also be differentially lost, making it difficult to demonstrate Mendelian inheritance. Formation of octopine-type tumours on nopaline positive plants occurs in a high percentage of inoculations. Transformed plants show several morphological traits which distinguish them from normal plants: they are smaller, have decreased apical dominance, show hypertrophy of the hypocotyl region, lower nodes, and petiole bases, and frequently form an extra spur of tissue in ray flowers.

Crown Gall Tumor

The amino acid lysopine was found in the free state in both primary normal and crown-gall tumor tissue of growing tobacco (Nicotianatabacum) and tomato (Lycopersiconesculentum) plants. Identification was made by means of co-chromatography with synthesized lysopine, electrophoresis, and column chromatography. Quantitative analysis showed that tumor tissue contained about 24 times as much lysopine as normal tissue.

Ferulic Acids

Cultures of normal tobacco callus tissue 3 weeks after subculture contain free and bound forms of cinnamic, caffeic, and ferulic acids and bergapten, and bound umbelliferone, esculetin, and scopoletin. Cultures of tobacco crown gall tumor tissue lack cinnamic acid, umbelliferone, and bergapten; but they contain free as well as bound esculetin and scopoletin, and higher total levels of each of these coumarins than normal tissue. It is suggested that biosynthesis of coumarins in tumor cells has been diverted from the umbelliferone–furanocoumarin pathway in favor of esculetin and scopoletin.
