Changes in polyamine and Tyramine Concentrations in Rice (Oryza sativa L.) during Maturation and Preharvest Sprouting

The levels of polyamines were measured to investigate the alternative nitrogen metabolism during maturation and sprouting in rice. The rice plants (cv. Ansanbyeo) were cultivated in 20-year-old nonfertilized field. The flag leaves and spikes were collected weekly after the earing stage and the seed...

Zusammenfassung:	The levels of polyamines were measured to investigate the alternative nitrogen metabolism during maturation and sprouting in rice. The rice plants (cv. Ansanbyeo) were cultivated in 20-year-old nonfertilized field. The flag leaves and spikes were collected weekly after the earing stage and the seed were harvested daily after lodging. Free, bound, and conjugated polyamines were analyzed using reverse phase HPLC. Putrescine, spermidine, spermine, agmatine and tyramine were the major amines found in rice.
