A comparison of the effects of 1,4-naphthoquinone and 2-hydroxy-1,4-naphthoquinone (lawsone) on indole-3-acetic acid (IAA)-induced growth of maize coleoptile cells
Abstract The effects of 1,4-naphthoquinone (NQ) and 2-hydroxy-1,4-naphthoquinone (NQ-2-OH) on indole-3-acetic acid (IAA)-induced growth, medium pH changes and membrane potential ($ E_{m} $) in maize (Zea mays L.) coleoptile cells were determined. In addition, the redox cycling properties of both nap...

| 520 | |a Abstract The effects of 1,4-naphthoquinone (NQ) and 2-hydroxy-1,4-naphthoquinone (NQ-2-OH) on indole-3-acetic acid (IAA)-induced growth, medium pH changes and membrane potential ($ E_{m} $) in maize (Zea mays L.) coleoptile cells were determined. In addition, the redox cycling properties of both naphthoquinones were also compared. The dose-response curves constructed for the effects of NQ and NQ-2-OH on endogenous and IAA-induced growth differ in shape. It was found that NQ was by 10–50% more effective in inhibiting IAA-induced growth in maize coleoptile segments than NQ-2-OH. Simultaneous measurements of growth and external medium pH indicated that NQ and NQ-2-OH reduced or eliminated proton extrusion at all of the concentrations used, excluding NQ at 1 µM. It was found that both naphthoquinones at concentrations higher than 10 µM caused the depolarisation of the membrane potential ($ E_{m} $). Additionally, compared to the controls, NQ- and NQ-2-OH-exposure of coleoptile segments, at concentrations higher than 10 µM, caused an elevation of the hydrogen peroxide ($ H_{2} $$ O_{2} $) production and plasma membrane redox activity. The highest catalase activity was observed at 10 µM NQ and it was ca. 18-fold greater (at 4 h) than in the control medium. Moreover, it was also found that NQ and NQ-2-OH, at all concentrations studied, increased the malondialdehyde content of coleoptile segments at 4 h of the experiment. The data presented here are discussed taking into account the “acid growth hypothesis” of auxin action and the mechanisms by which naphthoquinones interact with biological systems. | ||

In addition, the redox cycling properties of both naphthoquinones were also compared. The dose-response curves constructed for the effects of NQ and NQ-2-OH on endogenous and IAA-induced growth differ in shape. It was found that NQ was by 10–50% more effective in inhibiting IAA-induced growth in maize coleoptile segments than NQ-2-OH. Simultaneous measurements of growth and external medium pH indicated that NQ and NQ-2-OH reduced or eliminated proton extrusion at all of the concentrations used, excluding NQ at 1 µM.
