“…As eckols exhibit considerable fungicidal activity [ 53 , 54 ], we suggest that relatively high levels of these phlorotannins in P. canaliculata ( Figure 5 ) may help to control the fungus infection. Polyphenols are known to be involved in the interactions between vascular plants and symbiotic fungi; in particular, mycorrhizal infection leads to changes in polyphenolic profiles [ 55 , 56 ]. Sanders et al [ 57 ] showed that the brown alga Petroderma maculiforme , occurring in both free-living and lichenized state, continued producing high abundance of physodes under the nutritional burden of supporting a fungal symbiont.…”

Composition of Intracellular and Cell Wall-Bound Phlorotannin Fractions in Fucoid Algae Indicates Specific Functions of These Metabolites Dependent on the Chemical Structure

Accumulation of biologically active metabolites is a specific feature of plant biochemistry, directing the use of plants in numerous applications in the pharmaceutical and food industries. Among these substances, the plethora of phenolic compounds has attracted particular interest among researchers. Here, we report on new findings in phlorotannin research, a large group of multifunctional phenolic substances, produced in brown algae. Comprehensive LC-MS profiling of three algal species allowed us to depict the complex pattern of this structurally diverse compound group across different tissues and subcellular compartments. We compiled more than 30 different phlorotannin series in one sample and used accurate mass spectrometry to assign tentative structures to the observed ions based on the confirmed sum formulas. From that, we found that acetylation, hydroxylation, and oxidation are likely to be the most common in vivo modifications to phlorotannins. Using an alternative data mining strategy to cope with extensive coelution and structural isomers, we quantitatively compared the intensity of different phlorotannin series in species, tissues, and subcellular compartments to learn more about their physiological functions. The structure and intra-thallus profiles of cell wall-bound phlorotannins were studied here for the first time. We suggest that one of the major dibenzodioxin-type phlorotannin series may exclusively target integration into the cell wall of fucoid algae.

Screening for Changes on Iris germanica L. Rhizomes Following Inoculation with Arbuscular Mycorrhiza Using Fourier Transform Infrared Spectroscopy

et al. 2019

Iris germanica L. is an ornamental and medicinal plant used since ancient times for their rhizomes, still utilized today to obtain orris butter highly valued in perfumery. Iris germanica presents special root adaptations, which confers certain tolerance to water and salt stress, making it a good option in the context of the current climate trend. Aim of this study was to prospect the potential for biofortification of rhizomes using commercial arbuscular mycorrhizae (AM) application in field conditions for six Iris germanica cultivars. Plants presented Paris-type AM colonization. Rhizome samples collected after nine months from treatment and maturated, presented FT-IR (fourier transform infrared spectroscopy) spectra variation between experimental variants. Presence of the main metabolites in rhizome could be confirmed based on literature. Screening focused on two rhizome quality markers: carbohydrates, which influence plant development, and fatty acids, which are extractable from rhizome. Results suggest potential to enhance their accumulation in certain cultivars, such as ‘Pinafore Pink’ following AM application.

“…Although phenolic compounds are the major antioxidant class in plants, other compounds (such as betacyanins, tocopherol, ascorbic acid and β-carotene) may act as free radical scavengers, hence contributing to the oxidative stress stabilization (Janda et al, 2014;Brandão et al, 2014). Several studies have indicated that the regular intake of plant-origin products [such as fruits, vegetables, spices and medicinal herbs (as tea, for example)] prevents and /or reduces the risk of chronic and degenerative diseases that are triggered by cellular oxidative stress, particularly due to presence of substances with antioxidant activity like as phenolic compounds (Rumbaoa et al, 2009;Cardoso Silva et al, 2010;Engel et al, 2016). Despite their structural diversity, phenolic compounds are categorized into several classes.…”

Genetic, biochemical and physiological parameters can be changed by applying seaweed extract-based products. However, there is scarce information about the influence of seaweed extract on yarrow performance (Achillea millefolium L.), which is widely used in the folk medicine. Therefore, this study aimed to evaluate the effects of Ascophyllum nodosum extract on plant development (leaf and root biomass, and leaf area), physiological indexes (leaf weight ratio, and root: leaf ratio), secondary metabolite (phenolic compounds) content and antioxidant activity of yarrow. The experiment was carried out in a completely randomized design with 4 treatments (seaweed extract concentrations 0, 3, 6 and 9 mL L-1) and 10 replications. The higher concentration of seaweed extract caused higher total dry weight of plants (from 17.8 to 19%), especially due to increases in the root biomass (up to 28.5%). Only plants that received the highest concentration of seaweed-based product presented increments in the number of leaves when compared to the control plants (18.3 %). Furthermore, the use of A. nodosum extract 9 mL L-1 provided increases in the antioxidant activity and content of phenolic compounds in leaves (up to 30.44%). In conclusion, application of A. nodosum is a potential tool strategy to improve the quality of raw material from yarrow plants, since it increased the phenolic compound content and antioxidant activity in leaves, which are the plant organs commonly used in folk medicine.
