l-DOPA (l-3,4-dihydroxyphenylalanine) is a bioactive secondary metabolite which inhibits growth of many weed species. However, its mode of action is not well elucidated in plants. The present studies were conducted to evaluate the effect of l-DOPA on root growth of cucumber (Cucumis sativus L.) and the possible involvement of quinoproteins (quinone-incorporated proteins) in phytotoxicity of l-DOPA. The results revealed that l-DOPA significantly inhibited root growth, induced cell death, increased polyphenol oxidase (PPO) activity, reduced free cysteine content, and enhanced quinoprotein formation in cucumber roots. The decrease in free cysteine content and increase in PPO activity suggested that quinones covalently bind with cysteine to form quinoproteins. The quinoproteins may be involved in phytotoxic action of l-DOPA in cucumber roots.

The growth of maize seedlings was stimulated by shoot-applied 5-aminolevulinic acid 2 days after treatment at 90 and 120 μmol L −1 . The effects of 5-aminolevulinic acid on the activity of nitrate reductase (EC 1.6.6.2) and nitrite reductase (EC 1.7.7.1) and the chlorophyll, ammonium, heme and total free amino acid content were investigated by using maize seedlings to clarify the involvement of nitrogen metabolism and heme synthesis in the growth stimulation. 5-Aminolevulinic acid increased the level of nitrate reductase activity at 90 μmol L −1 and the ammonium and heme content at 90 and 120 μmol L −1 2 days after treatment. The total amino acid content increased by 90 and 150 μmol L −1 5-aminolevulinic acid 2 and 3 days after treatment, respectively. However, no significant change was observed in the activity of nitrite reductase or the chlorophyll content after the 5-aminolevulinic acid treatment. These results suggest that the enhancement of nitrogen metabolism by nitrate reductase activation is involved in the 5-aminolevulinic acid-induced stimulation of maize seedling growth. The activation of nitrate reductase might be related to an increase in the heme content following the 5-aminolevulinic acid treatment. 1518 71 54 T. Yonezawa et al.
