The root-hairless barley mutant brb used as model for assessment of role of root hairs in iron accumulation
(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 ... -
Mitochondria dysfunctions under Fe and S deficiency: is citric acid involved in the regulation of adaptive responses?
(2018)Within the last years, extensive information has been accumulated on the reciprocal influence between S and Fe nutrition at both physiological and molecular level in several plant species, but the mechanisms regulating S ... -
The effect of excess sulfate supply on iron accumulation in three graminaceous plants at the early vegetative phase
(PERGAMON-ELSEVIER SCIENCE LTD, 2016)In recent years it has been established a significant relationship between sulfur (S) and iron (Fe) nutrition. In particular, it has been demonstrated that S deprivation can hinder Fe acquisition in barley, maize and wheat. ... -
Does the sulfur assimilation pathway play a role in the response to Fe deficiency in maize (Zea mays L.) plants?
(2003)The finding that the methionine is the sole precursor of the mugineic acid family phytosiderophores induced us to evaluate whether sulfur assimilation pathway has a role in plant response to Fe deficiency. Maize plants ... -
Influence of Iron Nutrition on Sulphur Uptake and Metabolism in Maize (Zea mays L.) Roots
(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 ... -
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 ... -
Modulation of NO3- uptake by water-extractable humic substances: involvement of root plasma membrane H(+)ATPase
(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 ... -
The characterization of the adaptive responses of durum wheat to different Fe availability highlights an optimum Fe requirement threshold
(Elsevier Masson SAS, 2016)Plant mechanisms responding to iron (Fe) deficiency have been widely described; it is well known that Strategy II plants, as durum wheat, cope with this stress by increasing both the synthesis and secretion of phytosiderophores ... -
Terbuthylazine interferes with iron nutrition in maize (Zea mays) plants
(2017)Many chemicals, including herbicides, are routinely applied to crops for weed management and food production improvement. However, the intensive use of herbicides could lead eventually to a great environmental threat due ... -
Effect of three safeners on sulfur assimilation and iron deficiency response in barley (Hordeum vulgare) plants
(John Wiley and Sons Ltd, 2017)BACKGROUND: Safeners are agrochemicals used in agriculture to protect crops from herbicide injuries. They act by stimulating herbicide metabolism. As graminaceous plants, to cope with iron (Fe) deficiency, activate sulfur ...
