Effects of water-extratable humic substances on molecular physiology of nitrate uptake in two maize inbred lines with different nitrogen use efficiency
(eScholarship, University of California, 2009)Soil humic substances are known to positively influence plant growth and nutrition. In particular, low-molecular fractions have been shown to increase NO3- uptake and PM H+-ATPase activity and alter expression of related ... -
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 ... -
Two plasma membrane H+-ATPase genes are differentially expressed in iron-deficient cucumber plants
(2005)Aim of the present work was to investigate the involvement of plasma membrane (PM) H+-ATPase (E.C. 3.6.3.6) isoforms of cucumber (Cucumis sativus L.) in the response to Fe deficiency. Two PM H+-ATPase cDNAs (CsHA1 and ... -
Early transcriptomic response to Fe supply in Fe-deficient tomato plants is strongly influenced by the nature of the chelating agent
(BioMed Central Ltd., 2016)Background: It is well known that in the rhizosphere soluble Fe sources available for plants are mainly represented by a mixture of complexes between the micronutrient and organic ligands such as carboxylates and ... -
Development of Fe-deficiency responses in cucumber (Cucumis sativus L.) roots: involvement of plasma membrane H+-ATPase activity
(2000)One of the mechanisms through which some strategy I plants respond to Fe-deficiency is an enhanced acidification of the rhizosphere due to proton extrusion. It was previously demonstrated that under Fe-deficiency, a strong ...
