Abstract:
... Aluminum (Al), the third most abundant element overall, after silicon and oxygen, is found virtually in all food, air, soil and water. Under acidic conditions, Al is solubilized into [Al(H₂O)₆]³⁺, which is highly toxic to many plant species. Present paper reviewed Al toxicity and tolerance mechanism in agricultural plants with special reference to cereals and legumes. Even at micromolar concentrat ...

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:
... Species in the genus Erwinia cause diseases in many economically important plants. In May 2021, celery plants (Apium graveolens var. dulce ‘Queen of France’) showing soft rot symptoms were observed in greenhouses in Boye County, Baoding, Hebei Province (North China). Disease symptoms began with pinkish, water-soaked lesions on the midrib of stalks, but at the same time the leaves and roots were as ...

Subject:
Glycine max; aluminum; calcium; calcium carbonate; citrates; cultivars; hydroponics; introduced plants; magnesium; magnesium chloride; protons; root growth; roots; secretion; soil pH; soil solution; soybeans; toxicity
Abstract:
... Hydroponic studies with soybean (Glycine max [L.] Merr.) have shown that μmol L⁻¹ additions of Mg²⁺ were as effective in ameliorating Al rhizotoxicity as additions of Ca²⁺in the mmol L⁻¹ concentration range. The objectives of this study were to assess the ameliorative effects of Mg on soybean root growth in acidic subsoils and to relate the soil solution ionic compositions to soybean root growth. ...
