The root-hairless barley mutant brb used as model for assessment of role of root hairs in iron accumulation

Zuchi S; Cesco S; Gottardi S; Pinton R; Römheld V; Astolfi S (2011)
Main components of Strategy II mechanism for Fe uptake are secretion of chelating compounds, phytosiderophores, and specific uptake of Fe(III)-phytosiderophores complex. Since the amount of phytosiderophores secreted ...
Influence of Iron Nutrition on Sulphur Uptake and Metabolism in Maize (Zea mays L.) Roots

Astolfi S; Zuchi S; Cesco S; Varanini Z; Pinton R (2004)
Recent research has evidenced a relationship between Fe nutrition and S nutrition. Aim of the present work was to investigate the effect of Fe deficiency on the capacity of maize roots to take up and metabolize S. Maize ...
Modulation of NO3- uptake by water-extractable humic substances: involvement of root plasma membrane H(+)ATPase

Pinton R; Cesco S; Iacolettig G; Astolfi S; Varanini Z (1999)
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 maize root seedlings were exposed for 4 to 24 ...
Cadmium exposure affects iron acquisition in barley seedlings

Astolfi S; Ortolani MR; Paolacci AR; Cesco S; Pinton R; Ciaffi M (Società Italiana Di Chimica Agraria, 2013)
