0.01 mM diphenylene iodonium chloride treatment leads to an obvious decrease in the activity of ascorbate peroxidase in Clostera anachoreta larvae-wounded leaves
activity of ascorbate peroxidase is enhanced in Clostera anachoreta larvae-wounded leaves (immediate and sharp increase at 0.5 h, followed by a sudden decrease at 2 h, and then a slight increase at 6 h after damage)
APX activity in the 35S-PpAPX transgenic lines increases by 50% compared to the activity in the control lines, activity is 80% higher in the leaves in response to drought or salt stresses, the PpAPX transcript level is very low under normal growing conditions in rd29Ap-PpAPX plants, but clearly increased under drought stress
APX is easily inactivated by excess amounts of H2O2, chloroplastic APX looses its activity within 1 min in the absence of ascorbate when 20 mol equivalent of H2O2 is added
APX6 is a bona fide senescence-associated gene. High osmotic conditions, dark stress, and abscisic acid (ABA) activate APX6 expression in an age-dependent manner. APX6 expression is specifically induced in aging leaves and in response to senescence-promoting stimuli such as abscisic acid (ABA), extended darkness, and osmotic stress. apx6 mutants showed early developmental senescence and increased sensitivity to dark stress. Mutants of squamosa promoter binding protein-like7 (SPL7), the master regulator of copper homeostasis and miR398 expression, have a higher APX6 level compared to the wild-type, which further increases under copper deficiency. miR398 is a potential post-transcriptional regulator of APX6
CrAPX4 is downregulated using amiRNA technology to examine the role of APX for high-light (HL) acclimation. The CrAPX4 knockdown amiRNA lines show low APX activity and CrAPX4 transcript level without a change in CrAPX1 and CrAPX2 transcript levels, and monodehydroascorbate reductase (MDAR), dehydroascorbate reductase (DHAR), and glutathione reductase (GR) activities and transcript levels. Upon exposure to high-light (HL), CrAPX4 knockdown amiRNA lines show a modification in the expression of genes encoding the enzymes in the ascorbate-glutathione cycle, including an increase in transcript level of CrVTC2, a key enzyme for ascorbate (AsA) biosynthesis but a decrease in MDAR and DHAR transcription and activity after 1 h, followed by increases in reactive oxygen species production and lipid peroxidation after 6 h, and exhibit cell death after 9 h. Besides, AsA content and AsA/DHA (dehydroascorbate) ratio decrease in CrAPX4 knockdown amiRNA lines after prolonged HL treatment
drought, Pi-free, Cd, and Xanthomonas oryzae pv. oryzicola B8-12 treatments are able to significantly alter the expression profiles of rice APX isozymes, overview
drought, Pi-free, Cd, and Xanthomonas oryzae pv. oryzicola B8-12 treatments are able to significantly alter the expression profiles of rice APX isozymes, overview. Isozyme OsAPX3 is not affected by drought stress and by Cd stress
drought, Pi-free, Cd, and Xanthomonas oryzae pv. oryzicola B8-12 treatments are able to significantly alter the expression profiles of rice APX isozymes, overview. Isozyme OsAPX5 is unaffected by drought and Cd stresses
enzyme expression markedly increases in leaves of plants subjected to conditions of long-term treatment with salinity, whereas Apx transcript levels remain unaffected in detached leaves during short-term salt treatment
exogenous calcium enhances rice tolerance to acid rain stress by regulating isozymes composition and transcriptional expression of ascorbate peroxidase
exogenous calcium enhances rice tolerance to acid rain stress by regulating isozymes composition and transcriptional expression of ascorbate peroxidase. Simulated acid rain (SAR)stress (pH 3.5) upregulates the expression of APX1 and APX4 in rice leaves and the expression of APX1, APX2, and APX4 in rice roots
expression of PgAPX1 significantly increases under heat-stress conditions, transcript analysis suggests that the heat-shock element, HSE, motifs may be responsible for stress-specific expression of PgAPX1 by interacting with PgHSF
no ascorbate peroxidase activity is present in mature seeds but activity is detected after 24 h post imbibition and increases 14fold up to 144 h post imbibition
RcAPX expression is significantly suppressed by galls, Galla chinensis, resulting from the galling aphid Schlechtendalia chinensis parasitizing the vein or compound leaves of Rhus chinensis
salt stress, Na+ induces expression of OsAPx8, , NaCl-enhanced expression of OsAPx8 in rice roots is mediated through an accumulation of the plant hormone ABA
the application of either LaCl3 or EGTA reverses the effect of abscisic acid on chilling-treated plants, i.e. it leads to the decrease in ascorbate peroxidase activity
the gene expression profile of CsAPX1 encoding ascorbate peroxidase (APX) is regulated by light/dark conditions. AsA accumulation and APX activity are suppressed by light/dark conditions
transcript level and the total APX activity are highly induced in response to in vitro applied H2O2 or ethylene, up-regulated during fiber cell elongating
