Pseudomonas amygdali

The unusual cytokinins 1 -methylzeatin and its riboside, both with a methyl group instead of hydrogen atom in C -position of the side chain, were identified in the plant pathogenic bacteria Pseudomonas syringae subsp. savastanoi and P. amygdali ([40] and references therein, [102]). These compounds have not yet been detected in plants and nothing is known about the path(s) of their formation.
