Subject:
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 ...

Subject:
soil solution; subsoil; iron; dry matter accumulation; magnesium fertilizers; citric acid; Glycine max; calcium; root growth; adsorption; stress tolerance; liming; phytotoxicity; acid soils; fertilizer rates; nutrient availability; soybeans; root exudates; magnesium; aluminum; biodegradation
Abstract:
... Additions of micromolar concentrations of magnesium (Mg) to hydroponics enhance aluminum (Al) tolerance of soybean by increasing citrate secretion from roots and external complexation of toxic Al species. The objective of this study was to assess the ameliorative effect of Mg additions on soybean root elongation into mineralogically different acid soils. Roots of soybean seedlings grew for 28 days ...

3. Mitochondrial enzymes and citrate transporter contribute to the aluminium-induced citrate secretion from soybean (Glycine max) roots

Author:
Xu, Muyun; You, Jiangfeng; Hou, Ningning; Zhang, Hongmei; Chen, Guang; Yang, Zhenming
Source:
Functional plant biology 2010 v.37 no.4 pp. 285-295
ISSN:
1445-4408
Subject:
Glycine max; soybeans; roots; aluminum; phytotoxicity; disease resistance; citrates; metabolism; transport proteins; mitochondria; malate dehydrogenase; citrate (si)-synthase; aconitate hydratase; enzyme activity; dose response; protein secretion; gene expression regulation; transcription (genetics); plant growth; acid soils
Abstract:
... The concentration of soluble aluminium (Al) in the soil solution increases at low pH and the prevalence of toxic Al³⁺ cations represent the main factor limiting plant growth on acid soils. Citrate secretion from roots is an important Al-tolerance mechanism in many species including soybean. We isolated mitochondria from the roots of an Al-resistant soybean (Glycine max L.) cv. Jiyu 70 to investiga ...

Subject:
soil degradation; soil amendments; Mucuna; crop yield; animal manures; Ultisols; tropics; Oxisols; soil fertility; liming materials; Zea mays; Glycine max; cation exchange capacity; soil organic matter; corn; rice straw; upland soils; mulches; slags; phytotoxicity; nutrient availability; soybeans; phosphorus fertilizers; aluminum; ecological restoration; Indonesia
Abstract:
... Upland agriculture in Indonesia mainly relies on Ultisols and Oxisols, which have serious problems resulting from severe erosion and low organic-matter content. The objectives of the study were (i) to assess the effect of long-term rehabilitation techniques on soil organic carbon (SOC) and maize yields of a desurfaced Ultisol and (ii) to assess the effect of short-term rehabilitation techniques on ...

Plant and soil 2010 v.330 no.1-2 pp. 127-137
ISSN:

Subject:
Glycine max; abiotic stress; abscisic acid; aluminum; genotype; leaves; radionuclides; root growth; roots; soybeans; toxicity
Abstract:
... Abscisic acid (ABA) plays an important role in mediating some biotic and abiotic stresses. In the present study, to better understand the relationship of ABA production and Aluminum (Al)-resistance in plants, Al-resistance genotype (Jiyu70) of soybean was adopted to investigate the accumulation and transport of ABA in plants exposed to Al. Results showed that exogenous application of ABA and ABA s ...
