“…29,30 Piyatida et al found that B. cereus enhances the resistance to O 3 by increasing flavonoids in plant tissues. 31 Mohammad et al found that the total phenolic and flavonoid contents of pineapples and bananas increased significantly when exposed to ozone for 20 minutes. 32 A majority of the flavonoids in the pericarp of hot peppers increased upon treatment with ozone for 3 hours.…”

Ozone treatment at a suitable concentration can improve the antioxidant capacity of postharvest fruits.However, few studies have examined the antioxidant bioactive compounds in ozone-treated postharvest strawberries, especially in relation to proteomics. In this study, the total phenol content (TPC), total flavonoid content (TFC), and total anthocyanin content (TAC) were used as the main antioxidant compound indicators and unlabeled proteomics was used to study the metabolism of phenylpropanoids in postharvest strawberries (Jingtaoxiang) treated with different concentrations of ozone (0, 1, 3, and 5 ppm) throughout the duration of storage. The results showed that the postharvest strawberries treated with 5 ppm ozone concentration exhibited improved accumulation of total phenols, flavonoids and anthocyanins in the antioxidant bioactive compounds, which was beneficial to the expression of phenylpropanoid metabolism-related proteins over the whole storage period compared with the other three groups. The results of proteomics were consistent with the changes in the key metabolites of phenylpropanoids, which indicated that ozone treatment at a suitable concentration aids the accumulation of TPC, TAC and TFC by promoting the key proteins associated with phenylpropanoid metabolism.

“…Also, flavonoids within chloroplasts protect the function of the membrane during cellular dehydration (Inoue, 2011). Many data revealed that there is an interaction between the levels of induced flavonoids and antioxidant action under different stress treatments such as ozone, heat and salinity (Gondor et al, 2016;Martinez et al, 2016;Pheomphun et al, 2019). Mahajan and Yadav (2013) found that exogenous flavonoid quercetin and epicatechin regulates the antioxidant enzymes at transcriptional levels in tobacco seedlings.…”

Flavonoid Naringenin Alleviates Short-Term Osmotic and Salinity Stresses Through Regulating Photosynthetic Machinery and Chloroplastic Antioxidant Metabolism in Phaseolus vulgaris

The current study was conducted to demonstrate the possible roles of exogenously applied flavonoid naringenin (Nar) on the efficiency of PSII photochemistry and the responses of chloroplastic antioxidant of salt and osmotic-stressed Phaseolus vulgaris (cv. Yunus90). For this aim, plants were grown in a hydroponic culture and were treated with Nar (0.1 mM and 0.4 mM) alone or in a combination with salt (100 mM NaCl) and/or osmotic (10% Polyethylene glycol, −0.54 MPa). Both caused a reduction in water content (RWC), osmotic potential ( ), chlorophyll fluorescence (F v /F m ), and potential photochemical efficiency (F v /F o ). Nar reversed the changes on these parameters. The phenomenological fluxes (TR o /CS and ET o /CS) altered by stress were induced by Nar and Nar led to a notable increase in the performance index (PI ABS ) and the capacity of light reaction [ P o /(1-P o )]. Besides, Nar-applied plants exhibited higher specific fluxes values [ABS/RC, ET o /RC, and E o /(1-E o )] and decreasing controlled dissipation of energy (DI o /CS o and DI o /RC). The transcripts levels of psbA and psbD were lowered in stress-treated bean but upregulated in Nar-treated plants after stress exposure.Nar also alleviated the changes on gas exchange parameters [carbon assimilation rate (A), stomatal conductance (g s ), intercellular CO 2 concentrations (C i ), transpiration rate (E), and stomatal limitation (L s )]. By regulating the antioxidant metabolism of the isolated chloroplasts, Nar was able to control the toxic levels of hydrogen peroxide (H 2 O 2 ) and TBARS (lipid peroxidation) produced by stresses. Chloroplastic superoxide dismutase (SOD) activity reduced by stresses was increased by Nar. In response to NaCl, Nar increased the activities of ascorbate peroxidase (APX), glutathione reductase (GR), monodehydroascorbate reductase (MDHAR), and dehydroascorbate reductase (DHAR), as well as peroxidase (POX). Nar protected the bean chloroplasts by minimizing disturbances caused by NaCl exposure via the ascorbate (AsA) and glutathione (GSH) redox-based systems. Under Nar plus PEG, Nar maintained the AsA regeneration by

“…The highest CAT activity observed in T5 showed that it demonstrated higher tolerance to oxidative stress. Pheomphun et al (2019) reported that the increase in B. cereus populations was attributed to the significant increase in CAT activity and had the ability to protect Zamioculcas zamiifolia against O 3 stress conditions. It suggested that 5% BCP demonstrated higher protective effects against oxidative stress.…”

Spent mushroom substrate (SMS) is the by-products of mushroom production, which is mainly composed of disintegrated lignocellulosic biomass, mushroom mycelia and some minerals. The huge output and the lack of effective utilization methods make SMS becoming a serious environmental problem. In order to improve the application of SMS and SMS derived biochar (SBC), composted SMS (CSMS), SBC, combined plant growth-promoting rhizobacteria (PGPR, Bacillus subtilis BUABN-01 and Arthrobacter pascens BUAYN-122) and SBC immobilized PGPR (BCP) were applied in the lettuce seedling. Seven substrate treatments were used, including (1) CK, commercial control; (2) T1, CSMS based blank control; (3) T2, T1 with combined PGPR (9:1, v/v); (4) T3, T1 with SBC (19:1, v/v); (5) T4, T1 with SBC (9:1, v/v); (6) T5, T1 with BCP (19:1, v/v); (7) T6, T1 with BCP (9:1, v/v). The physicochemical properties of substrate, agronomic and physicochemical properties of lettuce and rhizospheric bacterial and fungal communities were investigated. The addition of SBC and BCP significantly (p < 0.05) improved the total nitrogen and available potassium content. The 5% (v/v) BCP addiction treatment (T5) represented the highest fresh weight of aboveground and underground, leave number, chlorophyll content and leaf anthocyanin content, and the lowest root malondialdehyde content. Moreover, high throughput sequencing revealed that the biochar immobilization enhanced the adaptability of PGPR. The addition of PGPR, SBC and BCP significantly enriched the unique bacterial biomarkers. The co-occurrence network analysis revealed that 5% BCP greatly increased the network complexity of rhizospheric microorganisms and improved the correlations of the two PGPR with other microorganisms. Furthermore, microbial functional prediction indicated that BCP enhanced the nutrient transport of rhizospheric microorganisms. This study showed the BCP can increase the agronomic properties of lettuce and improve the rhizospheric microbial community.
