Biossíntese de lignina em plantas submetidas ao déficit hídrico

Pubvet, 2020
Em seus ecossistemas, as plantas são submetidas a diversos potenciais inimigos, tanto os bióticos como os abióticos. No entanto, os vegetais por meio de mutações, seleção natural e mudanças evolutivas desenvolveram mecanismos de defesa não só estruturais

A comparison of the effects of drought on proline accumulation and peroxidases activity in leaves of Festuca rubra L. and Lolium perenne L.

Acta Societatis Botanicorum Poloniae, 2011
The effect of soil drought on leaf water content, proline content, and the activity of guaiacol (GuPX) and ascorbate (APX) peroxidases as well as the level of lipid peroxidation were investigated in leaves of drought resistant red fescue (Festuca rubra ...

Glutathione peroxidases as oncotargets

OncoTarget, 2017
Oxidative stress is a disturbance in the equilibrium among free radicals, reactive oxygen species, and endogenous antioxidant defense mechanisms. Oxidative stress is a result of imbalance between the production of reactive oxygen and the biological ...

High Auxin and High Phosphate Impact on RSL2 Expression and ROS-Homeostasis Linked to Root Hair Growth in Arabidopsis thaliana

Frontiers in Plant Science, 2018
Root hair size determines the surface area/volume ratio of the whole roots exposed to the nutrient and water pools, thereby likely impacting nutrient and water uptake rates.

Membrane-Bound Class III Peroxidases: Unexpected Enzymes with Exciting Functions

International Journal of Molecular Sciences, 2018
Class III peroxidases are heme-containing proteins of the secretory pathway with a high redundance and versatile functions. Many soluble peroxidases have been characterized in great detail, whereas only a few studies exist on membrane-bound isoenzymes ...

Intraspecific differentiation of Reed Grass Calamagrostis arundinacea (L.) Roth (Poaceae) populations revealed by peroxidase allozymes

Acta Societatis Botanicorum Poloniae, 2011
The genetic Variation of Reed Grass Calamagrostis arundinacea (L.) Roth was investigated in 25 populations in various geographic regions of Poland. A total of 907 individuals were sampled for electrophoretic analysis of peroxidase loci (11 allozymes ...

Thiol-Based Peroxidases and Ascorbate Peroxidases: Why Plants Rely on Multiple Peroxidase Systems in the Photosynthesizing Chloroplast?

Molecules and Cells, 2016
Photosynthesis is a highly robust process allowing for rapid adjustment to changing environmental conditions. The efficient acclimation depends on balanced redox metabolism and control of reactive oxygen species release which triggers signaling cascades ...

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

FEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.
