Iron reduction in iron-stressed plants of Actinidia deliciosa genotypes: Involvement of PM Fe(III)-chelate reductase and H+-ATPase activity
Micropropagated plantlets of the Actinidia rootstock D1, resistant to lime-induced iron (Fe) deficiency, and the Actinidia deliciosa line 2084 (sel. 2084), moderately sensitive to Fe starvation, were grown in nutrient ...
Water-extractable humic substances enhance iron deficiency responses by Fe-deficient cucumber plants
The ability of Fe-deficient cucumber plants to use iron complexed to a water-extractable humic substances fraction (WEHS), was investigated. Seven-day-old Fe-deficient plants were transferred to a nutrient solution ...
Modulation of NO3- uptake by water-extractable humic substances: involvement of root plasma membrane H(+)ATPase
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 ...
