Iron Mobilization and Mineralogical Alterations Induced by Iron-Deficient Cucumber Plants (Cucumis sativus L.) in a Calcareous Soil
(SCIENCE PRESS, 2018)Dicotyledons cope with ion (Fe) shortage by releasing low-molecular-weight organic compounds into the rhizosphere to mobilize Fe through reduction and complexation mechanisms. The effects induced by these root exudates on ... -
Degradation of citrate promotes copper co-precipitation within aluminium-(hydr)oxides in calcareous soils
(Springer Verlag, 2017)In this study, we provide experimental evidences that in calcareous soils microbial degradation/decomposition of citrate can promote Al-(hydr)oxide precipitation concurrently decreasing copper (Cu) solubility by a ... -
Silicon dynamics in the rhizosphere: Connections with iron mobilization
(WILEY-V C H VERLAG GMBH, 2016)Silicon (Si) is a beneficial element for plants as it increases their resistance to several biotic and abiotic stresses. In the rhizosphere, root exudates, especially when released by nutritionally stressed plants, promote ... -
New 'solutions' for floating cultivation system of ready-to-eat salad: A review
(ELSEVIER SCIENCE LONDON, 2015)Soilless cultivation systems represent an alternative to traditional agriculture, as they offer the possibility to reduce water use and to design nutrient formulations of the hydroponic solutions in order to maximize yield ... -
Copper accumulation in vineyard soils: Rhizosphere processes and agronomic practices to limit its toxicity
(PERGAMON-ELSEVIER SCIENCE LTD, 2016)Viticulture represents an important agricultural practice in many countries worldwide. Yet, the continuous use of fungicides has caused copper (Cu) accumulation in soils, which represent a major environmental and toxicological ... -
Does Fe accumulation in durum wheat seeds benefit from improved whole-plant sulfur nutrition?
(2018)Sulfur and iron balanced supply is of paramount importance for plants, since Fe homoeostasis in plants has been shown to be strongly dependent on sulfate availability; vice versa the adaptation to Fe deficiency requires ... -
Plant-microorganism-soil interactions influence the Fe availability in the rhizosphere of cucumber plants
(2015)Iron (Fe) is a very important element for plants, since it is involved in many biochemical processes and, often, for the low solubility of the natural Fe sources in soil, plants suffer from Fe deficiency, especially when ... -
Iron allocation in leaves of Fe-deficient cucumber plants fed with natural Fe complexes
(2015)Iron (Fe) sources available for plants in the rhizospheric solution are mainly a mixture of complexes between Fe and organic ligands, including phytosiderophores (PS) and water-extractable humic substances (WEHS). In ... -
Nutrient availability in the rhizosphere: A review
(2018)The rhizosphere is the volume of soil where the chemical (pH, redox potential, nutrient concentration and root exudates), physical (temperature, water availability and soil structure) and biological characteristics (microbial ... -
Combined effect of organic acids and flavonoids on the mobilization of major and trace elements from soil
(2015)Combinations of different molecules usually co-exuded by plant roots in soil can significantly affect the mobilization of mineral elements from soil. The flavonoids rutin and quercetin appeared to be highly efficient in ...
