Maize glutathione-dependent formaldehyde dehydrogenase: protein sequence and catalytic properties.

abstract：:Chloride ions are necessary to compensate for the positively charged potassium ions imported into guard cells of Allium cepa L. during stomatal opening. Therefore an external Cl(-) supply of intact Allium plants is important. But high levels of chloride have been found to reduce the sensitivity of the starch-lacking s...
