Reactive Oxygen Species (ROS) and Nucleic Acid Modifications during Seed Dormancy
Plants, 2020 The seed is the propagule of higher plants and allows its dissemination and the survival of the species. Seed dormancy prevents premature germination under favourable conditions.

Reactive oxygen species (ROS): Beneficial companions of plants’ developmental processes
Frontiers in Plant Science, 2016 Reactive oxygen species (ROS) are continuously generated inevitably in the redox reactions of plants, including respiration and photosynthesis. In earlier studies, ROS were considered as toxic by-products of aerobic pathways of the metabolism.

Mitochondrial Reactive Oxygen Species (ROS) and ROS-Induced ROS Release
Physiological Reviews, 2014 Byproducts of normal mitochondrial metabolism and homeostasis include the buildup of potentially damaging levels of reactive oxygen species (ROS), Ca2+, etc., which must be normalized. Evidence suggests that brief mitochondrial permeability transition pore (mPTP) openings play an important physiological role maintaining healthy mitochondria homeostasis.

Ca2+-Induced Mitochondrial ROS Regulate the Early Embryonic Cell Cycle
Cell Reports, 2018 Summary: While it is appreciated that reactive oxygen species (ROS) can act as second messengers in both homeostastic and stress response signaling pathways, potential roles for ROS during early vertebrate development have remained largely unexplored ...

Production and Detection of Reactive Oxygen Species (ROS) in Cancers [PDF]
Journal of Visualized Experiments, 2011 Reactive oxygen species include a number of molecules that damage DNA and RNA and oxidize proteins and lipids (lipid peroxydation). These reactive molecules contain an oxygen and include H(2;)O(2;) (hydrogen peroxide), NO (nitric oxide), O(2;)(-) (oxide anion), peroxynitrite (ONOO(-)), hydrochlorous acid (HOCl), and hydroxyl radical (OH(-)).

A REVIEW OF REACTIVE OXYGEN SPECIES (ROS) IN PLANTS
Journal of Advanced Scientific Research, 2023 Reactive oxygen species (ROS) are highly reactive intermediates of oxygen formed during successive reduction ofoxygen. Most common ROS include singlet oxygen 1O2, Superoxide (O2•−), Hydrogen Peroxide (H2O2), and Hydroxylradical (•OH). ROS are produced as by-products of normal aerobic metabolism in plants.

ROS and the DNA damage response in cancer
Redox Biology, 2019 Reactive oxygen species (ROS) are a group of short-lived, highly reactive, oxygen-containing molecules that can induce DNA damage and affect the DNA damage response (DDR).

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.
