“…Salicylic acid and jasmonic acid are essential signal molecules in the process of pathogen infection [ 20 , 21 ], which are involved in various aspects of regulating plant growth, environmental stress, and defense response to pathogens [ 22 , 23 ]. There is a close relationship between JA- and SA-mediated signal transduction pathway, synergy, and antagonism [ 24 , 25 ].…”

Sulfur has been previously reported to modulate plant growth and exhibit significant anti-microbial activities. However, the mechanism underlying its diverse effects on plant pathogens has not been elucidated completely. The present study conducted the two-year field experiment of sulfur application to control kiwifruit canker from 2017 to 2018. For the first time, our study uncovered activation of plant disease resistance by salicylic acid after sulfur application in kiwifruit. The results indicated that when the sulfur concentration was 1.5–2.0 kg m−3, the induced effect of kiwifruit canker reached more than 70%. Meanwhile, a salicylic acid high lever was accompanied by the decline of jasmonic acid. Further analysis revealed the high expression of the defense gene, especially AcPR-1, which is a marker of the salicylic acid signaling pathway. Additionally, AcICS1, another critical gene of salicylic acid synthesis, was also highly expressed. All contributed to the synthesis of increasing salicylic acid content in kiwifruit leaves. Moreover, the first key lignin biosynthetic AcPAL gene was marked up-regulated. Thereafter, accumulation of lignin content in the kiwifruit stem and the higher deposition of lignin were visible in histochemical analysis. Moreover, the activity of the endochitinase activity of kiwifruit leaves increased significantly. We suggest that the sulfur-induced resistance against Pseudomonas syringae pv. actinidiae via salicylic activates systemic acquired resistance to enhance plant immune response in kiwifruit.

“…It is of full juicy, rounded shape, and pleasant flavor, making it a well-received citrus fruit for consumers in China ( Cao et al, 2019 ; Huang et al, 2021a ). However, harvested Ponkan fruit is exceptionally prone to fungal infection by pathogens, such as Penicillium italicum , P. digitatum , and Geotrichum citri-aurantii ; among them, P. italicum is a causal pathogen of citrus blue mold (BM) during storage, transportation, and market, seriously limiting the storage-life and reducing the commercial value of the harvested fruit ( Kanashiro et al, 2020 ; Duan et al, 2021 ; Moosa et al, 2021 ). Currently, controlling citrus BM is generally achieved by postharvest application of synthetic fungicides, which is considered the cheapest and most effective approach to reduce the decay incidence after harvest.…”

“…Generally, the defense and protection mechanisms of fruits can be enhanced by the induction of disease resistance against postharvest fungal infection ( Xu et al, 2021 ). Novel measures have been developed to take no account of synthetic fungicides in the management and control of citrus postharvest fungal disease development, such as edible film ( Vera-Guzmán et al, 2019 ; Huang et al, 2021a ), phytohormone ( La Spada et al, 2021 ; Moosa et al, 2021 ), and biological control ( Wang et al, 2022 ). Among them, the postharvest application of plant-derived antifungal agents (PAAs) to trigger resistance in citrus fruit has been considered as a promising control approach.…”

“…Increasing evidence has well demonstrated that the inducted resistance by PAAs has become a promising potential strategy in response to the challenge of fungal infections ( Chen et al, 2019b ; Duan et al, 2021 ; Li et al, 2021a ; Oulahal and Degraeve, 2022 ). Recently, some PAAs, such as poplar bud extract and its main component, namely, pinocembrin ( Yang et al, 2016 ), citral ( Tao et al, 2014 ), limonin ( Li et al, 2021b ), salicylic acid, and plant essential oil ( Moosa et al, 2021 ), are effective in the suppression of P. italicum growth and in inducing resistance to citrus postharvest blue mold. In addition, Dou et al (2021) reported that 0.6 g/L epsilon-poly-L-lysine (ε-PL) effectively reduced BM incidence in “Fuji” apple by activating the host-defense responses to P. expansum infection.…”

Antofine Triggers the Resistance Against Penicillium italicum in Ponkan Fruit by Driving AsA-GSH Cycle and ROS-Scavenging System

Postharvest fungal infection can accelerate the quality deterioration of Ponkan fruit and reduce its commodity value. Penicillium italicum is the causal pathogen of blue mold in harvested citrus fruits, not only causing huge fungal decay but also leading to quality deterioration. In our preliminary study, antofine (ATF) was found to have a great potential for significant in vitro suppression of P. italicum growth. However, the regulatory mechanism underpinning ATF-triggered resistance against P. italicum in citrus fruit remains unclear. Here, the protective effects of ATF treatment on blue mold development in harvested Ponkan fruit involving the enhancement of ROS-scavenging system were investigated. Results showed that ATF treatment delayed blue mold development and peel firmness loss. Moreover, the increase of electrolyte leakage, O2•– production, and malonyldialdehyde accumulation was significantly inhibited by ATF treatment. The ATF-treated Ponkan fruit maintained an elevated antioxidant capacity, as evidenced by inducted the increase in glutathione (GSH) content, delayed the declines of ascorbic acid (AsA) content and GSH/oxidized GSH ratio, and enhanced the activities of superoxide dismutase, catalase, peroxidase, and six key AsA-GSH cycle-related enzymes, along with their encoding gene expressions, thereby maintaining ROS homeostasis and reducing postharvest blue mold in harvested Ponkan fruit. Collectively, the current study revealed a control mechanism based on ATF-triggered resistance and maintenance of a higher redox state by driving AsA-GSH cycle and ROS-scavenging system in P. italicum-infected Ponkan fruit.

“…italicum infection and fruit decay after harvest. However, long-term use of synthetic fungicides is increasingly becoming limited on account of numerous unsatisfactory problems, such as long degradation period, emergence of resistant pathogens, environmental pollution, ecological destruction, and emerging concern over fungicide residues on citrus fruits by consumers. , Today, there are numerous safe alternatives to synthetic fungicides that could be applied in the control of postharvest fungal decay in citrus fruits, such as plant extracts, salicylic acid (SA), nitric oxide (NO), chlorine dioxide (ClO 2 ), and antagonistic microorganisms or their volatile organic compounds. − …”

7-Demethoxytylophorine (DEM), a natural water-soluble phenanthroindolizidine alkaloid, has a great potential for in vitro suppression of Penicillium italicum growth. In the present study, we investigated the ability of DEM to confer resistance against P. italicum in harvested “Newhall” navel orange and the underlying mechanism. Results from the in vivo experiment showed that DEM treatment delayed blue mold development. The water-soaked lesion diameter in 40 mg L–1 DEM-treated fruit was 35.2% lower than that in the control after 96 h. Moreover, the decrease in peel firmness loss and increase in electrolyte leakage, superoxide anion (O2 •–) production, and malondialdehyde (MDA) content were significantly inhibited by DEM treatment. Hydrogen peroxide (H2O2) burst in DEM-treated fruit at the early stage of P. italicum infection contributed to the conferred resistance by increasing the activities of lignin biosynthesis-related enzymes, along with the expressions of their encoding genes, resulting in lignin accumulation. The DEM-treated fruit maintained an elevated antioxidant capacity, as evidenced by high levels of ascorbic acid and glutathione content, and enhanced or upregulated the activities and gene expression levels of APX, GR, MDHAR, DHAR, GPX, and GST, thereby maintaining ROS homeostasis and reducing postharvest blue mold. Collectively, the results in the present study revealed a control mechanism in which DEM treatment conferred the resistance against P. italicum infection in harvested “Newhall” navel orange fruit by activating lignin biosynthesis and maintaining the redox balance.
