In agro-ecosystem, plant pathogens hamper food quality, crop yield, and global food
security. Manipulation of naturally occurring defense mechanisms in host plants is an …

Plants are exposed to various environmental stresses in their lifespan that threaten their
survival. Reactive oxygen species (ROS), the byproducts of aerobic metabolism, are …

Flavonoids are a special category of hydroxylated phenolic compounds having an aromatic
ring structure. Quercetin is aspecial subclass of flavonoid. It is a bioactive natural compound …

Flavonoids are plant specialized metabolites that consist of one oxygenated and two
aromatic rings. Different flavonoids are grouped according to the oxidation degree of the …

The free radicals along with several reactive oxygen species (ROS) and reactive nitrogen
species (RNS) are known to play a dual role in the biological living system which carries a …

Whether flavonoids play significant antioxidant roles in plants challenged by photooxidative
stress of different origin has been largely debated over the last few decades. A critical review …

In the natural environment, plants are exposed to a variety of biotic and abiotic stress
conditions that trigger rapid changes in the production and scavenging of reactive oxygen …

Main conclusion This review summarizes the anti-stress effects of flavonoids in plants and
highlights its role in the regulation of polar auxin transport and free radical scavenging …

Reactive oxygen species (ROS) were initially recognized as toxic by-products of aerobic
metabolism. In recent years, it has become apparent that ROS plays an important signaling …

Reactive oxygen species (ROS) regulate plant growth and development. ROS are kept at
low levels in cells to prevent oxidative damage, allowing them to be effective signaling …
