Response of Phenylpropanoid Pathway and the Role of Polyphenols in Plants under Abiotic Stress

Molecules, Journal Year: 2019, Volume and Issue: 24(13), P. 2452 - 2452

Published: July 4, 2019

Phenolic compounds are an important class of plant secondary metabolites which play crucial physiological roles throughout the life cycle. Phenolics produced under optimal and suboptimal conditions in plants key developmental processes like cell division, hormonal regulation, photosynthetic activity, nutrient mineralization, reproduction. Plants exhibit increased synthesis polyphenols such as phenolic acids flavonoids abiotic stress conditions, help to cope with environmental constraints. Phenylpropanoid biosynthetic pathway is activated (drought, heavy metal, salinity, high/low temperature, ultraviolet radiations) resulting accumulation various which, among other roles, have potential scavenge harmful reactive oxygen species. Deepening research focuses on responses great interest for scientific community. In present article, we discuss biochemical molecular mechanisms related activation phenylpropanoid metabolism describe phenolic-mediated tolerance plants. An attempt has been made provide updated brand-new information about response phenolics a challenging environment.

Polyphenols: A concise overview on the chemistry, occurrence, and human health

Phytotherapy Research, Journal Year: 2019, Volume and Issue: 33(9), P. 2221 - 2243

Published: July 29, 2019

This review gives an updated picture of each class phenolic compounds and their properties. The most common classification implies the subdivision phenolics in two main groups: flavonoids (e.g., anthocyanins, flavanols, flavanones, flavonols, flavonones, isoflavones) non‐flavonoids acids, xanthones, stilbens, lignans, tannins) polyphenols. great interest polyphenols is associated with high potential application for food preservation therapeutic beneficial use. relationship between polyphenol intake human health has been exploited special reference to cardiovascular diseases, hypertension, diabetes, metabolic syndrome, obesity, cancer. use current existing databases bioactive including described as key tools research.

Effect of salt stress on growth, chlorophyll content, lipid peroxidation and antioxidant defence systems in Phaseolus vulgaris L.

South African Journal of Botany, Journal Year: 2016, Volume and Issue: 105, P. 306 - 312

Published: May 14, 2016

Salinity is one of the major abiotic stresses which affects plant cell metabolism and reduces productivity. Variations in antioxidant defence systems under salinity among two bean genotypes were investigated. Our results indicate that difference between response to a quantitative trait rather than qualitative since they develop same strategies with significant variation rate synthesis accumulation, exemption based on phenolic compounds. For both genotypes, induced marked reduction dry matter gain roots shoots along oxidative stress as indicated by increase malondialdehyde content. In addition, photosynthetic pigments decreased salinity. The only we found was decrease total production compounds leaves detectable low-yielding genotype high high-yielding may have better protection against damages increasing activity enzymes amounts flavonoids ascorbic acid salinity, allows maintaining higher yield even upon conditions.

Bioactivities of Phenolics by Focusing on Suppression of Chronic Diseases: A Review

International Journal of Molecular Sciences, Journal Year: 2018, Volume and Issue: 19(6), P. 1573 - 1573

Published: May 25, 2018

Phenolics, which are secondary metabolites of plants, exhibit remarkable bioactivities. In this contribution, we have focused on their protective effect against chronic diseases rather than antioxidant activities, been widely discussed in the literature. A large body epidemiological studies has proven bioactivities phenolics both standard compounds and natural extracts: namely, anticancer, anti-inflammatory, antibacterial activities as well reducing diabetes, cardiovascular disease, neurodegenerative disease. Phenolics also display anti-analgesic, anti-allergic, anti-Alzheimer’s properties. Thus, review provides crucial information for better understanding foods fills a gap existing collective overall knowledge field.

Glycosylation Is a Major Regulator of Phenylpropanoid Availability and Biological Activity in Plants

Frontiers in Plant Science, Journal Year: 2016, Volume and Issue: 7

The phenylpropanoid pathway in plants is responsible for the biosynthesis of a huge amount secondary metabolites derived from phenylalanine and tyrosine. Both flavonoids lignins are synthesized at end this very diverse metabolic pathway, as well many intermediate molecules whose precise biological functions remain largely unknown. diversity these can be further increased under action UDP-glycosyltransferases (UGTs) leading to production glycosylated hydroxycinnamates related aldehydes, alcohols esters. Glycosylation change solubility, stability toxic potential, influencing compartmentalization activity. (De)-glycosylation therefore represents an extremely important regulation point homeostasis. In article we review recent knowledge on enzymes involved regulating glycosylation status availability different subcellular compartments. We also examine potential link between monolignol lignification by exploring co-expression lignin genes phenolic (de)glycosylation genes. Of roles linked with their particular chemical properties, phenylpropanoids often correlated plant's stress management strategies that regulated glycosylation. UGTs instance influence resistance during infection microorganisms mechanisms environmental changes. impact flavonoid colour flowers, leaves, seeds fruits will discussed.
