Supportive effect of naringenin on NaCl-induced toxicity in Carthamus tinctorius seedlings

Abstract

BackgroundThe exogenous application of priming molecules to plants helps them to develop tolerance against salinity stress. In the present study, we used exogenous naringenin (0.5 mM) pretreatment before the stress in sa ower seedlings under 25 mM NaCl to elucidate the role of naringenin to alleviate oxidative conditions associated with salinity complications. ResultsOur results showed biomass, leaf relative water content, chlorophyll content, K + content, and K + /Na + ratio were negatively affected by 25 mM NaCl. However, the H 2 O 2 accumulation, malondialdehyde (MDA) content, antioxidant enzymes and Na + content of NaCl-stressed sa ower seedlings were remarkably increased. The results obtained in the present study showed the bene cial effects of the pre-treatment of naringenin in sa ower seedlings under non-salinity stress condition with respect to increasing plant biomass, total phenolic compound, radical scavenging activity (RSA), soluble sugar content, proline, glutathione, enzymatic antioxidants, and K + content. Also, the results showed that naringenin pretreatment can (partly) be overcome NaCl-induced stress on sa ower seedlings, probably due to higher accumulation of plant biomass, total phenolic compound, RSA, catalase (CAT) activity, and K + /Na + ratio as well as lowering the H 2 O 2 and MDA content in the leaves. ConclusionsGenerally, it could be concluded that, pre-treatment of naringenin before stress could partly diminish NaClcaused oxidative stress in sa ower seedlings, probably due to improvement in enzymatic and nonenzymatic antioxidant and reduced cell membrane damage.

Changes in the Antioxidant Potential of Camellia sinensis Cultures under the Influence of Phenolic Precursors

“…While in the cells of the Moringa oleifera plant this trend was significantly less pronounced, herewith in quinoa sprouts there was no statistically significant difference between the experimental and control variants [ 30 , 46 ]. There are data confirming the increase in the accumulation of PCs in Carthamus tinctorius and Vigna radiata seedlings in the presence of Nar, while in the first case this indicator increased almost two-fold [ 27 , 28 ].…”

“…The described effect of Nar is confirmed by the data obtained in the work of Sharma et al where a similar trend was noted [ 27 ]. At the same time, there was shown no change in water content using the example of Carthamus tinctorius seedlings in the presence of the indicated above precursor [ 28 ]. It is worth noting that for Phe, a similarity to our data effect was noted for the Vitex agnus castus shoot cultures and Cicer arietinum seedlings [ 29 , 30 ].…”

“…Changes in the growing conditions of plant cells, including the administration of additional components into the nutrient medium, can cause changes in the functioning of their antioxidant system [ 37 ]. The criterion of this process is the level of lipid peroxidation (LPO), often assessed by the content of malondialdehyde (MDA) [ 28 ]. The statistical processing has shown that LPO level depends on the precursor treatment ( Table 6 ).…”

The exogenous application of naringenin and rosmarinic acid modulates functional traits in Lepidium sativum

“…13 It has recently been demonstrated that Nar contributes to enhanced plant growth, increased osmotic regulation, and increased vegetative development, biochemical accumulation, and protein bioavailability. 14 Phenolic-derived compounds may have various synergistic or antagonistic effects on plants when combined, [15][16][17] but these effects are not currently well known. Therefore, the aim of this study is to investigate the potential synergistic, neutral, and antagonistic effects of exogenous RA and Nar application on the metabolic processes of L. sativum, aiming to enhance our understanding of how these compounds influence the overall bioactive compounds in plants.…”

“…Naringenin (4′,5,7‐trihydroxyflavanone) (Nar) is another phenolic with antioxidant, free radical scavenger, anti‐inflammatory, immune system modulation properties, widely distributed in citrus fruits 13 . It has recently been demonstrated that Nar contributes to enhanced plant growth, increased osmotic regulation, and increased vegetative development, biochemical accumulation, and protein bioavailability 14 …”
