Disappearance of Electric Spatial Pattern in a Bean Root under Circumstances in Nitrogen Gas

概要
- 論文の詳細を見る
A spatial pattern of electric potential in the growing root was studied with a usualmicroeJectrode and a multi-electrode measuring apparatus, which made possible asimultaneous measurement of electric potentials along the root. The pattern of sur-face electric potential disappeared along the entire root length when air surroundingthe plant was replaced with nitrogen gas for about 2 h. Disappearance of a large peakof surface potential around 10 mm from the root tip preceded both the decrease in thegrowth speed and the change in pH of the aqueous medium to neutral in the elonga-tion region, while this region showed a localized acidification in normal conditions.Supply of air recovered the spatial patterns of electric potential and pH. Proton ac-cumulation within the cell wall following activation of H" pumps was suggested toparticipate directly in the growth.
