Název v původním jazyce

Aminoaldehyde dehydrogenase activity during wound healing of mechanically injured pea seedlings

Popis výsledku v původním jazyce

Abstract: Aminoaldehyde dehydrogenase (AMADH, EC 1.2.1.19) is an enzyme, which in association with amine oxidase participates in polyamine catabolism. In plants, the enzyme is well characterized in pea seedlings. In this study, we used etiolated and light-grown pea seedlings as model plants to evaluate the possible AMADH role in response to stress caused by mechanical damage. In the beginning, activity distribution of AMADH, amine oxidase and peroxidase in organs of 7-d-old intact pea seedlings was analyzed. To perform mechanical damage, stems of 10-d-old seedlings were each divided into four segments of equal length. Then the top (= fourth) segments were longitudinally cut with a lancet. During healing, the injured segments and their control counterparts were harvested in 1-d intervals and analyzed for activity of the above enzymes and polyamine and GABA (4-aminobutyrate) concentrations. The injury elicited increases in AMADH, amine oxidase and peroxidase activities in both etiolated
