Cytokinin activity of ureidopurine derivatives related to a modified nucleoside found in transfer RNA.
By use of a radioactive labeling technique N-(nebularin-6-ylcarbamoyl)threonine has been detected in plant transfer RNA. Derivatives of this nucleoside promote cell division of a cytokinin-requiring soya bean tissue.
