The presence of lignin in an insoluble fraction obtained from tobacco callus tissue was shown by the production of vanillin and syringaldehyde on oxidation of the material with nitrobenzene in alkali.

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.

Cultivation Medium

The influence of benzene, phenol and catechol on the tobacco callus tissue (<i>Nicotiana tabacum</i> L. cv. Wisconsin No. 38) cultivated <i>in vitro</i> was studied. Although inhibition of callus tissue growth in relation to the control was observed in all variants, the benzene-induced inhibition was the most significant. When catechol and phenol were added to the cultivation medium together, callus tissue growth was similar to that of the control. The addition of catechol to the medium containing phenol presumably reduces the toxic effect of phenol on the callus tissue examined. Callus tissue growing in the presence of phenol, benzene and cathechol became senescent more rapidly than in the control. Moreover microscopic examination revealed significant changes in the callus structure.

Abstract We examined growth of the Dutch elm disease fungus, Ophiostoma ulmi, on callus derived from a susceptible American elm (Ulmus amencana, selection A), an American elm of intermediate resistance (U. americana, selection 8630), and a resistant Siberian elm (Ulmus pumlia) at 16, 22, and 28°C (61,72, and 83°F) and inoculation concentrations of 15 × 106, 2 × 106, or 0.3 × 106 conidia/ml. After 72 hours, the rates of fungal growth for all treatments were most rapid on calli from the American 8630 selection followed by the American A and Sibenan selections. While fungal growth was more rapid over American 8630, it was more dense on American A. Most rapid fungal growth occurred at 22°C (72°F) and was directly proportional to the inoculum concentration. A significant interaction was noted between callus source and temperature.
