1 sty 2015 · Research into plant oxidative stress has shown great potential for developing stress-tolerant crops. This can be achieved through the use of directed evolution techniques to prevent protein oxidation, bioengineering of antioxidant activities as well as modification of ROS sensing mechanisms.
6 sie 2019 · Oxidative stress is produced by increasing the number of reactive oxygen species or free radicals, which results in early aging, increased permeability, ions leakage from the cell...
3 cze 2020 · In the natural environment, plants are constantly exposed to abiotic stresses, such as extreme temperatures, salt stress, drought and heavy metals that have a huge impact on agriculture worldwide and consequently, lead to massive economic losses.
1 sty 2023 · The accumulation of reactive oxygen species (ROS) caused by abiotic or biotic stresses generates oxidative stress in plant cells. To prevent the spread or to stop this chain reaction, antioxidant systems are activated, transforming free radicals (oxidants) into less toxic molecules for the cells.
19 sie 2023 · Increased levels of ROS/RNS, generated from both endogenous (mitochondria, NADPH oxidases) and/or exogenous sources (radiation, certain drugs, foods, cigarette smoking, pollution) result in a harmful condition termed oxidative stress (“bad stress”).
14 wrz 2021 · Attempts to improve the oxidative stress resilience by restricting ROS production or accumulation are expected to not only prevent oxidative damage to cellular constituents, but also have wide systemic effects propagated through the cellular redox homeostasis.
27 maj 2021 · The authors offer a critical review of both the oxidative stress generated and antioxidant defense activated in response to a wide array of stress agents, including soil salinity, water deficit, metal ions excess, and high and low temperatures.
