“…This indicates that SA and 1-MCP treatment could inhibit the production of H 2 O 2 to varying degrees, and the inhibitory effect of 1-MCP+SA treatment was better than those of 1-MCP and SA treatments. Similar to our results, the H 2 O 2 content of “Yali” pear ( 32 ) and goji berries ( 33 ) was also significantly reduced by 1-MCP and SA treatments. The reason for the reduced H 2 O 2 content in the treated winter jujube fruit may be that 1-MCP and SA could enhance the activities of antioxidant enzymes such as APX, POD, SOD, and CAT, thus delaying fruit senescence and extending the shelf life of winter jujube fruit.…”

“…Impact of -MCP+SA treatment on SOD, POD, CAT, APX, GR, and PAL activity in winter jujube fruit during shelf life Numerous studies have shown that during storage, the antioxidant defense system (e.g., SOD, POD, CAT, APX, GR, and PAL) in fruit can remove ROS produced during metabolism, reduce the oxidative damage caused by ROS to cells, and delay fruit senescence (33). SOD is an important ROS scavenging enzyme in plant enzymatic defense system, which can reduce the accumulation of ROS in fruit by catalyzing the transformation of O −• 2 into H 2 O 2 in tissues (35).…”

Winter jujube fruit is susceptible to aging, peel reddening, dehydration, shrinkage, and tissue softening during shelf life after it is removed from the cold storage conditions. In this study, the effects of 1-methylcyclopropene (1-MCP) and salicylic acid (SA) on the quality of winter jujube fruit during shelf life were investigated by measuring physiological indexes and the activities of antioxidant enzymes and enzymes related to reactive oxygen species (ROS) metabolism of winter jujube fruit. The results showed that 1-MCP treatment and SA treatment suppressed weight loss, respiratory rate, malondialdehyde (MDA) content, H2O2 content, and O2-· production rate, but improved firmness, color difference (ΔE), soluble solid content (SSC), titratable acidity (TA), superoxide dismutase (SOD), peroxidase (POD), catalase (CAT), ascorbate peroxidase (APX), glutathione reductase (GR), phenylalanine ammonia-lyase (PAL) activities, ascorbic acid content, glutathione content, total phenolic content, and total flavonoid content in comparison with the control. Particularly, the combined treatment of 1-MCP and SA (1-MCP+SA treatment) showed the maximum efficacy compared to the 1-MCP treatment and SA treatment alone. 1-MCP+SA treatment exhibited the best preservation effect, followed by SA treatment and 1-MCP treatment. Thus, the combined treatment of 1-MCP and SA is an effective approach to maintain the postharvest quality of winter jujube fruit and extend the shelf life.

“…Cinnamyl-alcohol dehydrogenase (CAD) catalyzes the conversion of cinnamaldehyde to cinnamyl alcohol, which is involved in lignin synthesis, whereas chalcone synthase (CHS) is mainly involved in flavonoid synthesis (Ge et al, 2018 ; Li et al, 2021 ). In previous research, the activity and gene expression level of PAL, CHS, and CAD in goji berry were activated, resulting in a higher content of phenylpropanoid metabolites, thus further enhancing disease resistance (Zhang et al, 2021a ). In our study, the expression levels of AcPAL, AcCAD , and AcCHS in H 2 S-treated kiwifruit were markedly higher than in CK, but these expression levels were upregulated in the later stage.…”

Botryosphaeria dothidea is a major pathogen responsible for postharvest kiwifruit soft rot. This study aimed to determine the influence of hydrogen sulfide (H2S) on postharvest resistance to kiwifruit soft rot and the antifungal role of H2S against B. dothidea. The results indicated that H2S (20 μl L−1) restricted the lesion area following inoculation with B. dothidea. H2S enhanced the production of shikimic acid, tyrosine, tryptophan, and phenylalanine while also increasing the total phenols, flavonoids, and lignin. H2S upregulated the expression of AcDHQS, AcSDH, AcSK, AcPAL, AcCAD, and AcCHS. Additionally, sodium hydrosulfide (NaHS)-released H2S inhibited mycelial growth. NaHS concentrations of 20 and 40 mmol L−1 significantly decreased the mycelial weight and malondialdehyde content (MDA) content while increasing cell membrane conductivity and membrane leakage. The results indicate that H2S induces resistance in kiwifruit via a microbicidal role and amino acid metabolism involved in postharvest kiwifruit disease resistance.

“…However, studies have reported accumulation of HCAAs (coumaryltyramide and feruloyltyramide) accompanied by elevated SA levels and pathogenesis-related genes induction ( Campos et al, 2014 ). The production of ferulic acid, p -coumaric acid, and sinapic acid was stimulated by exogenous SA ( Zhang et al, 2021 ). In turn, exogenous HCAs can enhance these plant hormones changes and improve plant resistance ( Figure 2 ).…”

The compounds involved in the hydroxycinnamic acid amide (HCAA) pathway are an important class of metabolites in plants. Extensive studies have reported that a variety of plant hydroxycinnamamides exhibit pivotal roles in plant–pathogen interactions, such as p-coumaroylagmatine and ferulic acid. The aim of this review is to discuss the emerging findings on the functions of hydroxycinnamic acid amides (HCAAs) accumulation associated with plant defenses against plant pathologies, antimicrobial activity of HCAAs, and the mechanism of HCAAs involved in plant immune responses (such as reactive oxygen species (ROS), cell wall response, plant defense hormones, and stomatal immunity). However, these advances have also revealed the complexity of HCAAs participation in plant defense reactions, and many mysteries remain to be revealed. This review provides an overview of the mechanistic and conceptual insights obtained so far and highlights areas for future exploration of phytochemical defense metabolites.
