Expression of Peroxidase-like Genes, H2O2 Production, and Peroxidase Activity During the Hypersensitive Response to Xanthomonas campestris pv. vesicatoria in Capsicum annuum

Molecular Plant-Microbe Interactions, 2003
Pepper ascorbate peroxidase-like (CAPOA1), thioredoxin peroxidase-like (CAPOT1), and peroxidase-like (CAPO1) clones were isolated from pepper leaves inoculated with avirulent strain Bv5-4a of Xanthomonas campestris pv. vesicatoria.

Development of a Genome-Edited Tomato With High Ascorbate Content During Later Stage of Fruit Ripening Through Mutation of SlAPX4

Frontiers in Plant Science, 2022
Ascorbate is an essential antioxidant substance for humans. Due to the lack of ascorbate biosynthetic enzyme, a human must intake ascorbate from the food source.

Nitric oxide increases the enzymatic activity of three ascorbate peroxidase isoforms in soybean root nodules

, 2011
Ascorbate peroxidase is one of the major enzymes regulating the levels of H2O2 in plants and plays a crucial role in maintaining root nodule redox status.

Drought induced programmed cell death and associated changes in antioxidants, proteases, and lipid peroxidation in wheat leaves

Biologia Plantarum, 2013
Two wheat (Triticum aestivum L.) genotypes with varying degree of drought tolerance were used to analyze programmed cell death (PCD) and related biochemical changes under drought stress.

Endogenous ascorbate restrains apoplastic peroxidase activity during sunflower leaf development [PDF]

, 2012
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.

Nitric Oxide Inhibition of Tobacco Catalase and Ascorbate Peroxidase

Molecular Plant-Microbe Interactions, 2000
We used a variety of nitric oxide (NO) donors to demonstrate that NO inhibits the activities of tobacco catalase and ascorbate peroxidase (APX). This inhibition appears to be reversible because removal of the NO donor led to a significant recovery of ...

Iron triggers a rapid induction of ascorbate peroxidase gene expression in Brassica napus

, 1997
In plants, only ferritin gene expression has been reported to be iron-dependent. Here it is demonstrated that an iron overload of Brassica napus seedlings causes a large and rapid accumulation of ascorbate peroxidase transcripts, a plant-specific ...

Effects of lanthanum on the antioxidant capacity of chloroplasts and chlorophyll fluorescence parameters of maize seedlings under chromium stress

Photosynthetica, 2019
Effects of lanthanum chloride (LaCl3) on chromium tolerance of maize were investigated at chloroplast level. The results showed that Cr stress significantly increased activities of ascorbate peroxidase, glutathione reductase, monodehydro-ascorbate ...

Comparison of two peroxidases with high potential for biotechnology applications – HRP vs. APEX2

Computational and Structural Biotechnology Journal
Peroxidases are essential elements in many biotechnological applications. An especially interesting concept involves split enzymes, where the enzyme is separated into two smaller and inactive proteins that can dimerize into a fully active enzyme.
