Ascorbate peroxidase overexpression protects Leishmania braziliensis against trivalent antimony effects
(Fundação Oswaldo Cruz, 2019)
Endogenous ascorbate restrains apoplastic peroxidase activity during sunflower leaf development
(Wiley Blackwell Publishing, Inc, 2012-10-08)
Several apoplastic enzymes have been implicated in the control of elongation growth of plant cells. Among them, peroxidases contribute to both loosening and stiffening of the cell wall. They appear to be regulated by various ...
Nitric oxide is a ubiquitous signal for maintaining redox balance in plant cells: regulation of ascorbate peroxidase as a case study
(Oxford University Press, 2015-03)
Oxidative and nitrosative stresses and their respective antioxidant responses are common metabolic adjustments operating in all biological systems. These stresses result from an increase in reactive oxygen species (ROS) ...
Extraction and partial characterization of peroxidase from Copaifera langsdorffii Desf. leaves

Analysis of tolerance to copper and zinc in Aechmea blanchetiana grown in vitro
(Springer, 2012-03-01)
The aim of this study was to evaluate the growth and development of Aechmea blanchetiana Baker L.B. Sm. in vitro on medium with 0.0, 0.145, 1.45 and 14.5 mu M Cu and 0.0, 2.75, 27.5 and 275 mu M Zn. Significant accumulation ...

Quercetin and indole 3-butyric acid (IBA) as rooting inducers in Eucalyptus grandis × E. urophylla
(2015-01-01)
Vegetative propagation is the main form of Eucalyptus cutting production, but some clones are still difficult to propagate, including rooting. Auxins and co-factors such as flavonoids can improve root development. This ...
Auxin induces redox regulation of ascorbate peroxidase 1 activity by S-nitrosylation/denitrosylation balance resulting in changes of root growth pattern in Arabidopsis
(Oxford University Press, 2013-05)
S-nitrosylation of Cys-residues is one of the molecular mechanisms driven by nitric oxide (NO) for regulating biological functions of key proteins. While the studies on S-nitrosylation of Cys residues have served for ...
Salinity and osmotic stress trigger different antioxidant responses related to cytosolic ascorbate peroxidase knockdown in rice roots
(2016-11-01)
Salinity and osmotic stress trigger distinct signals in roots, which might induce differences in antioxidant responses. To clarify these relationships, transgenic rice plants silenced in both cytosolic ascorbate peroxidases ...
