Free amines, present in healthy leaves of barley and in leaves infected by brown rust (P. hordei Otth.), are partially characterized. The concentrations of 5 amines present in both kinds of tissue rise following infection, and at least 3 extra amines are detectable in rusted tissue. The concentration of the polyamine, spermidine, increases rapidly by 6 days after inoculation and, at sporulation, it is 6-7 times that in comparable healthy tissues. The possible involvement of polyamines in the green island syndrome is discussed.
