“…Identity assignments were performed on an Agilent 1100 Series system (Agilent, Waldbronn, Germany), equipped with DAD (G1315B) (Agilent) and LC/MSD Trap VL (G2445C VL) (Agilent) electrospray ionization mass spectrometry system, coupled to an Agilent Chem Station (version B.01.03) data‐processing station. The chromatographic separation method (HPLC‐DAD) for the determination of phenolic compounds, mainly hydroxycinnamic acids and flavonols, was developed based on the procedure reported by Parada et al . via the use of a Kromasil ClassicShell‐2.5‐C 18 (4.6 × 100 mm, 2.5 μm) column and a C 18 precolumn (Novapak; Waters, Milford, MA, USA; 22 × 3.9 mm, 4 μm).…”

BACKGROUND: Arbuscular mycorrhizal (AM) fungi establish symbioses with most agricultural plants and improves growthunder soil stress conditions. The present study aimed to evaluate the functional contribution of 2 AM fungal inocula (a native consortium isolated from saline soils of the Atacama Desert, 'HMC', and a reference inoculum Claroideoglomus claroideum, 'Cc') on the growth and antioxidant compounds of two cultivars of lettuce (Lactuca sativa cvs. 'Grand Rapids' and 'Lollo Bionda') at increasing salt stress conditions (0, 40, and 80 mmol L -1 NaCl). At 60 days of plant growth, the symbiotic development, biomass production, lipid peroxidation, proline content, antioxidant enzymes, phenolic compound profiles and antioxidant activity were evaluated. RESULTS: The 2 AM inocula differentially colonized the roots of Grand Rapids and Lollo Bionda lettuce plants. The AM symbioses increased proline synthesis and superoxide dismutase, catalase and ascorbate peroxidase activities and diminished phenolic compound synthesis and oxidative damage in lettuce, which was related positively to a higher growth of inoculated plants under salt exposure. The higher concentration of phenolic compounds induced by salinity in non-inoculated plants was associated with high oxidative stress and low fresh biomass production.CONCLUSION: Modulation of salinity stress in lettuce by AM root colonization is a result of changes of antioxidant enzymatic systems that reduce oxidative damage and sustain growth. The application of AM fungi to improve crop production by means of directed inoculation with efficient AM fungal strains may enhance lettuce production on soils plagued with salinity worldwide.

“…Nevertheless, there is no information about antioxidant concentrations in strawberry plants cultivated in the Chilean Andisols, where the bioavailability of P is deficient. In a recent related study, Parada et al . demonstrated that arbuscular mycorrhizal (AM) colonization increased total antioxidant activity even with a decrease in total anthocyanins, suggesting that a series of antioxidant compounds could be responsive to the main factors that influence P nutrition, such as AM symbiosis and both the type and doses of P fertilizer.…”

BACKGROUND: Strawberries are consumed worldwide. In Chile, strawberry production has been established in Andisols, were phosphorus is scarce. Traditional fertilization (TF) and organic fertilization (OF) have both been established there. This study examined their impact on the polyphenolic content of strawberries. RESULTS: Two anthocyanins were identified by high performance liquid chromatography with diode array detection coupled to mass spectrometry (HPLC-DAD-ESI-MS/MS). The average total anthocyanin concentrations were found to be 651 mg kg −1 fresh weight in 100% OF, which represents a 56% increase compared to fruits that were not fertilized. In the case of flavonols, only quercetin-rhamnoside was identified, and its concentration reached 14.6 mg kg −1 with 100% OF. The ascorbic acid concentration reached 0.54 g kg −1 in 50% TF (a 20% increase over fruits without fertilization, WF). The antioxidant activities slightly increased in the fruits subjected to TF and OF in comparison with WF treatment. CONCLUSION: These results support a management strategy for obtaining the best quality and potential beneficial effects in health by increasing anthocyanins and other polyphenols under OF. ReagentsThe commercial standard of pelargonidin-3-glucoside chloride (98.95%) was obtained from Phytolab (Vestenbergsgreuth, Germany). Quercetin (> 95%) and ascorbic acid (99.7%) was acquired from Sigma-Aldrich (Steinheim, Germany). The standards of TROLOX (6-hydroxy-2,5,7,8-tetramethylchromane-2-carboxilic acid), ABTS (2,2 ′ -azino-bis(3-ethylbenzothiazoline-6-sulphonic acid)), gallic acid and sodium carbonate were obtained from Sigma-Aldrich. HPLC grade solvents as water, methanol, acetonitrile and p.a. grade as formic acid, ammoniac, and hydrochloric acid were acquired from Merck (Darmstandt, Germany). Identification and quantification of anthocyanins and flavonolsHigh performance liquid chromatography with diode array detection coupled to mass spectrometry (HPLC-DAD-ESI-MS/MS) analyses of anthocyanins were carried out using a Shimadzu HPLC system (Tokyo, Japan) equipped with a quaternary LC-20AT pump with a DGU-20A5R degassed unit, a CTO-20A oven, an SIL-20a autosampler, and a UV-vis diode array spectrophotometer (SPD-M20A). The compounds were identified by a HPLC-DAD system coupled to a mass spectrometer (QTrap LC/MS/MS 3200 Applied Biosystem MDS Sciex system (Foster City, CA, USA)). The instrument was controlled and data were collected using Analyst J Sci Food Agric 2019; 99: 2404-2410

“…Oliveira et al reported an increase in the production of total flavonoids, vitexin‐2‐ O‐ rhamnoside, and orientin in Passiflora alata when inoculated with Gigaspora albida and grown in vermicompost. On the other hand, in a study with another fruit plant, Fragaria ananassa (strawberry), Parada et al reported that anthocyanin values were not affected by the joint action of mycorrhization and organic or chemical fertilizers. In ginger ( Zingiber officinale ), leaves and rhizome presented higher concentrations of phenolic compounds, antioxidant activity, and essential oils when the plants were inoculated with Claroideoglomus etunicatum and grown in organic substrate, confirming that the application of the fungus associated with organic fertilizers may increase the synthesis of plant compounds .…”

Use of mycorrhizal fungi releases the application of organic fertilizers to increase the production of leaf vitexin in yellow passion fruit

et al. 2020

BACKGROUND: Low-cost organic fertilizers, such as coconut powder and vermicompost, and arbuscular mycorrhizal fungi (AMF) may benefit the Passiflora edulis f. flavicarpa plant. However, it has not been established whether the joint application of these inputs may increase the production of vitexin and other molecules associated with the phytotherapeutic properties of this plant. Here, we tested the hypothesis that the application of AMF and organic fertilizers maximizes the production of bioactive compounds in leaves of P. edulis. RESULTS: The inoculation of Acaulospora longula into P. edulis grown in fertilization-free soil promoted an increase of 86% in the concentration of leaf vitexin, 10.29% in the concentration of total phenols, and 13.78% in the concentration of total tannins in relation to the AMF-free control, rendering soil fertilization superfluous.CONCLUSION: The application of A. longula increases the production of foliar biomolecules, such as vitexin, in yellow passion fruit plants. Thus, the addition of coconut powder and vermicompost to the substrate composition is not necessary, leading to the commercialized production of phytomass in the herbal medicines industry.
