“…In bean crops ( Phaseolus vulgaris ) it has been reported that the increase in ROS displays a defensive response of antioxidant enzymes and likewise a stimulation of the enzymatic efficiency of phenyl ammonium lyase (PAL) and tyrosine ammonium lyase (TAL), which are involved in the synthesis of antioxidant compounds such as phenolic acids and flavonoids 46 . In tea ( Camellia sinensis ) it has been shown that, under stress conditions, there is a positive regulation in the genes involved in the metabolic pathway of phenylpropanoids, including the genes that code for 4‐coumarate: CoA ligase (4CL), cinnamate‐4‐hydroxylase (C4H), chalcone isomerase (CHI), PAL, chalcone synthase (CHS), flavonol synthase (FLS), flavonone‐3‐hydroxylase (F3H), flavonoid 3′5″‐ hydroxylase (F3′5″), flavonoid 3′‐hydroxylase (F3′H), dihydroflavonol 4‐reductase (DFR), isoflavone reductase (IFR), UDP flavonoid glycosyltransferase (UFGT) and isoflavone synthase (IFS) 47 . In the CB2011‐509 genotype, the presence of HCADs predominates compared to anthocyanins, which may be related to the partial pigmentation of tubers.…”

In all genotypes, it was observed that the concentration of total phenolics was much higher with respect to the amounts of anthocyanins and HCADs, which may indicate that phenols in polymeric forms are the major compounds.…”

Metabolic and antioxidant effects of inoculation with arbuscular mycorrhizal fungi in crops of flesh‐coloured Solanum tuberosum treated with fungicides

BACKGROUND: Solanum tuberosum tubers have higher content of phenolic compounds such as hydroxycinnamic acid derivatives (HCAD) and anthocyanins in coloured genotypes. The use of fungicides for crops is common, but there are few studies regarding the interaction of fungicides and arbuscular mycorrhizal fungi (AMF). Here, the AMF-plant interactions and the metabolic responses of three potato genotypes with different tuber colorations (VR808, CB2011-509 and CB2011-104) inoculated with Claroideoglomus claroideum (CC), Claroideoglomus lamellosum (HMC26) or Funneliformis mosseae (HMC7) were studied together with the use of the fungicides MONCUT (M) and ReflectXtra (R). Mycorrhizal traits, phenolic compound profiles and antioxidant activity (AA) were evaluated.RESULTS: Despite only two HCADs being identified, with 5-caffeolquinic acid the most abundant, four anthocyanins were detected only in purple potato genotypes. The anthocyanin and HCAD profiles, as well as AA, showed that the CB2011-104 genotype had better characteristics than the other genotypes, while VR808 and CB509 showed similar responses. The responses were dependent on the specific combinations of genotype, fungicide and the AMF strain, and generally showed better responses when colonized by AMFs.CONCLUSION: The three potato genotypes had differential responses depending on the inoculated AMFs and the fungicide applied before sowing, where the optimal combinations for antioxidant response, mycorrhization degree and performance were HMC26/R for VR808, HMC7/M for CB2011-509 and HMC26/M for CB2011-104. Our results suggest the existence of functional compatibility that can be registered as beneficial effects even at the genotypic level of the host regarding a specific AMF strain.

“…Plants with larger leaf areas have a higher transpiration-to-evaporation ratio, resulting in more efficient water use. A variety of biochemical, physiological, and chemical changes were induced by drought stress, resulting in membrane injury and cell function loss, together with a decrease in plant growth [81]. Drought severity and frequency are expected to increase due to climate change-induced modifications in typical precipitation patterns.…”

Do Abiotic Stresses Affect the Aroma of Damask Roses?

Roses are popular ornamental plants all over the world. Rosa damascena Mill., also known as the damask rose, is a well-known scented rose species cultivated to produce essential oil. The essential oils obtained are high in volatile organic compounds (VOCs), which are in demand across the pharmaceutical, food, perfume, and cosmetic industries. Citronellol, nonadecane, heneicosane, caryophyllene, geraniol, nerol, linalool, and phenyl ethyl acetate are the most important components of the rose essential oil. Abiotic factors, including as environmental stress and stress generated by agricultural practises, frequently exert a selective impact on particular floral characteristics, hence influencing the overall quality and quantity of rose products. Additionally, it has been observed that the existence of stress exerts a notable impact on the chemical composition and abundance of aromatic compounds present in roses. Therefore, understanding the factors that affect the biosynthesis of VOCs, especially those representing the aroma and scent of rose, as a response to abiotic stress is important. This review provides comprehensive information on plant taxonomy, an overview of the volatolomics involving aromatic profiles, and describes the influence of abiotic stresses on the biosynthesis of the VOCs in damask rose.

“…This accumulation of phenolics is attributed to the fact that the biosynthesis rate of phenolics is higher than the consumption rate during storage (Becerra‐Moreno et al., 2015; Surjadinata et al., 2017). It is well‐known that plants can perceive external stimuli and activate a series of defense mechanisms to induce metabolism, thus mitigating stress to adapt to changing environments, especially secondary metabolism in plants (Bartwal et al., 2013; Samynathan et al., 2021). The defensive role of secondary metabolites has been demonstrated by in vitro examination of plants by modern techniques (Zaynab et al., 2018).…”

Ultrasonic washing has been widely applied to the postharvest storage of fruits and vegetables as a residue‐free physical washing technology, which plays an important role in improving shelf‐life, safety, and nutritional value. Phenolics are a large group of phytochemicals widespread in fruits and vegetables, and they have been considered potential protective factors against some diseases because of potent antioxidative properties. Previous studies have shown that ultrasonic washing can increase the phenolic content of fruits and vegetables immediately or during storage through the induction of plant stress responses, which is of great significance for improving the functional and nutritional value of fruits and vegetables. However, the mechanisms of ultrasound as an elicitor to improve the phenolic content remain controversial. Therefore, this review summarizes the applications of ultrasonic washing to increase the phenolic content in fruits and vegetables. Meanwhile, the corresponding physiological stress response mechanisms of the phenolic accumulation in terms of immediate stress responses (i.e., higher extractability of phenolics) and late stress responses (i.e., metabolism of phenolics) are expounded. Moreover, a hypothetical model is proposed to explain phenolic biosynthesis triggered by signaling molecules produced under ultrasound stress, including primary signal (i.e., extracellular adenosine triphosphate) and secondary signals (e.g., reactive oxygen species, Ca2+, NO, jasmonates, and ethylene). Additionally, the techno‐economic feasibility of ultrasonic washing technology is also discussed. Further, challenges and trends for further development of ultrasonic washing as an abiotic elicitor applied to the postharvest storage of fruits and vegetables are presented.
