Exogenous application of rutin and gallic acid regulate antioxidants and alleviate reactive oxygen generation in Oryza sativa L.

Abstract

The effect of rutin and gallic acid on growth, phytochemical and defense gene activation of rice ( L.) was investigated. The seeds of rice were primed with different concentrations of rutin and gallic acid (10-60 µg mL) to explicate the effect on germination on water agar plates. Further, to study the effect of most effective concentrations of gallic acid (60 µg mL) and rutin (50 µg mL), greenhouse pot experiment was set up to determine the changes in growth, antioxidant and defense parameters. The results revealed more pronounced effect of gallic acid on total chlorophyll and carotenoids as well as on total flavonoid content and free radical scavenging activities. Gene expression analysis of and genes involved in strengthening the plant defense further validated the results obtained from the biochemical analysis. Microscopic analysis also confirmed reduction in total reactive oxygen species, free radicals like HO and O by exogenous application of gallic acid and rutin. The data obtained thus suggest that both gallic acid and rutin can affect the growth and physiology of rice plants and therefore can be used to develop effective plant growth promoters and as substitute of biofertilizers for maximizing their use in field conditions.

Improvement in Heat Tolerance of Creeping Bentgrass with Melatonin, Rutin, and Silicon

“…Rutin improved creeping bentgrass responses to heat stress via enhanced TQ and CHL but did not have a major effect on lipid peroxidation or antioxidant enzyme activities or fatty acid composition of leaf tissues. Similar results were found by Singh et al (2017), as the total antioxidant capacity of rice plants treated with rutin were not significantly different from control plants but the ROS levels were lower in rutin-treated plants. Rutin is thought to interact with phospholipids at the lipidwater interface and reduce oxidative stress of lipids (Agati et al, 2013).…”

The application of a biostimulant based on tannins affects root architecture and improves tolerance to salinity in tomato plants

“…The strong antioxidant properties of GA (#2), and its derivatives, have been reported in literature, and several studies claim the possible role and application of GA in plant nutrition at different stages of growth, especially in early root and plant development 26,27 . For example, Singh and co-workers showed that the application of exogenous GA on rice seeds led to an increase of root length compared to the control 27 . Moreover, Negi and colleagues showed that GA might have an auxin-like function, directly acting on root length and development 17 .…”

“…Also, ferulic acid reacts as a natural protector against ultra-violet radiation known to cause skin disorders such as cancer and acceleration of skin aging. Rutin and gallic acid also help to strengthen veins and to inhibit the formation of amyloid fibrils, the principal causes of Alzheimer's diseases, respectively (Singh et al, 2017).…”
