Purpose The rationale of this paper is to review the state of the art regarding the biotic and
abiotic reactions that can influence Fe availability in soils. In soil, the management-induced …

Plants produce and release in the surrounding soil, the so-called rhizosphere, a vast variety
of secondary metabolites. Among them, flavonoids are the most studied, mainly for their role …

Plants release a multitude of organic compounds into the rhizosphere, some of which are
flavonoids. These products of secondary metabolism are mainly studied for their antioxidant …

In the rhizosphere, exudates from plants and microorganisms as well as stable soil organic
matter influence processes that can control plant growth, microbial infections, and nutrient …

Poor iron ( F e) availability in soil represents one of the most important limiting factors of
agricultural production and is closely linked to physical, chemical and biological processes …

The effect of a water extractable humic substances fraction (WEHS) on nitrate uptake and
plasma membrane (pm) H + -ATPase activity of maize roots was investigated. Four days old …

Improvement of plant iron nutrition as a consequence of metal complexation by humic
substances (HS) extracted from different sources has been widely reported. The presence of …

Since the studies by Liebig (1856), it is well known that plants, as long as they are adequately
supplied with light and mineral nutrients, can live in the absence of the organic and …

Roots of plants growing in their natural environment have evolved and live in close contact
with the solid phase of the soil; this interaction can determine changes both in root physiology …

Aim of the present work was to investigate the involvement of plasma membrane (PM) H + -ATPase
(EC 3.6.3.6) isoforms of cucumber (Cucumis sativus L.) in the response to Fe …
