Subject:
aluminum; antioxidants; cell wall components; cell walls; citrates; cultivars; enzyme activity; hemicellulose; lipid peroxidation; malondialdehyde; peroxidase; plasma membrane; root growth; superoxide dismutase; triticale
Abstract:
... Two triticale cultivars ZC 237 (Al-resistant) and ZC 1890 (Al-sensitive) were used to investigate the effects of 30 to 100 μM Al on antioxidative enzyme activity, lipid peroxidation and cell wall composition. In ZC 1890, the root elongation was significantly inhibited after 1-h exposure to 50 μM Al, the changes in hemicellulose fraction were clearly detected after 2-h Al exposure, while the peroxi ...

Glycine max; aluminum; citrates; cultivars; cycloheximide; exudation; mitochondrial membrane; plasma membrane; protein synthesis; protein synthesis inhibitors; pyridoxal; roots; secretion; soybeans; transporters
Abstract:
... To further understand the process of Al-induced citrate secretion from soybean roots, the effect of protein synthesis inhibitor, anion channel blockers, and citrate carrier inhibitors on Al-induced citrate exudation was investigated in Al-resistant soybean cultivar PI 416937. Citrate exudation from roots increased with the increase of Al concentration from 10 to 50 μM and initiated after 4 h of Al ...

Abstract:
... Aluminum (Al) is the main limiting factor for crop production in acidic soils. Efflux of organic acids is one of the mechanisms that determine Al-tolerance, and an Al-activated citrate transporter (multidrug and toxic compound extrusion) MATE1 gene is involved in different species. The contribution of the rye MATE1 gene (ScMATE1) depends on the rye (Secale cereale L.) cultivars and the crosses ana ...
