Metabolic aspects of growth in HU-treated crown-gall tissue cultures. II. Helianthus annuus

The dynamics of growth and changes in nucleic acid and protein contents in sunflower calluses and tumours cultured in hydroxyurea (HU) containing media were examined. HU-induced changes in healthy tissues ran in parallel always in the same direction, in tumourous ones however an uncoupling between D...
