“…In this study, several HSP and sHSP genes were identified as DEGs. Few HSP DEGs were repressed however, most of the HSP and all the sHSP DEGs were induced in expression by EPT at 1 d and 2 d. This result was similar to those of prior reports on apples (Son et al, 2012), peaches (Spadoni et al, 2014) and oranges (Perotti et al, 2015).…”

Pineapple [Ananas comosus (L.) Merr.] is an important tropical fruit. The pineapple fruits that are ripened in the hightemperature season have better quality, whereas those ripened in low-temperature season are acidic in taste. Elevated postharvest temperature (EPT) could enhance the quality of winter-harvested pineapple fruit. Based on transcriptome and differentially expressed genes analysis, we explored the GO (Gene Ontology) terms and KEGG (Kyoto Encyclopedia of Genes and Genomes) metabolic pathways associated with the EPT treatment and the differentially expressed heat response genes of pineapple fruit after EPT treatment. GO classifications suggested that DEGs (differentially expressed genes) were predominantly annotated to "response to stimulus", "response to external stimulus" and "aromatic compound biosynthetic process" in the biological process ontology, "hydrolase activity" and "glucosidase activity" in the molecular function ontology, as well as "intrinsic to membrane" and "cell wall" in the cellular component ontology. KEGG metabolic pathways analysis revealed that the DEGs were dominantly enriched to "starch and sucrose metabolism", "biosynthesis of secondary metabolites", "pentose and glucuronate interconversions", "carotenoid biosynthesis", "metabolic pathways" "galactose metabolism" and "plant hormone signal transduction". Nineteen HSP (heat shock protein) and sHSP (small HSP) DEGs were screened, and most of them were up-regulated by EPT. Most of the transcription factor genes, including HSF, bHLH, WRKY, MYB, AP2/ERF, bZIP and NAC, were down-regulated by EPT. The SOD (Superoxide dismutase) genes were induced by EPT, while most of the POD (Peroxidase) and CAT (Catalase) genes were repressed. This work would help to understand the molecular mechanisms for EPT process to improve the quality of pineapple fruits.

“…Studies on the performance of water temperatures ranging from 40 to 65°C have been conducted (Palou et al, 2002a ; García et al, 2016 ). Hot water treatment (HWT) was found to interrupt fungal spore growth for 24–48 h by the accumulation of secondary metabolites such as PR proteins, phytoalexins, accumulation of lignins in fruit infected by fungus, and production of ROS contributing to resistance against P. digitatum and P. italicum in citrus fruit (Nafussi et al, 2001 ; Yun et al, 2013 ; Perotti et al, 2015 ; Sui et al, 2016 ). Curing is another HWT post-harvest decay control method whereby citrus fruits are exposed for 2–3 days to air atmospheres heated to temperatures higher than 30°C at high relative humidity (RH >90%) (Palou, 2009 ).…”

Green mold (Penicillium digitatum) and blue mold (Penicillium italicum) are among the most economically impactful post-harvest diseases of citrus fruit worldwide. Post-harvest citrus diseases are largely controlled with synthetic fungicides such as pyrimethanil, imazalil, fludioxonil, and thiabendazole. Due to their toxic effects, prolonged and excessive application of these fungicides is gradually restricted in favor of safe and more eco-friendly alternatives. This review comprehensively describes alternative methods for the control of P. digitatum and P. italicum: (a) antagonistic micro-organisms, (b) plant extracts and essential oils, (c) biofungicides, (d) chitosan and chitosan-based citrus coatings, (e) heat treatments, (f) ionizing and non-ionizing irradiations, (g) food additives, and (h) synthetic elicitors. Integrating multiple approaches such as the application of biocontrol agents with food additives or heat treatments have overcome some drawbacks to single treatments. In addition, integrating treatment approaches could produce an additive or synergistic effect on controlling both molds for a satisfactory level of disease reduction in post-harvest citrus. Further research is warranted on plant resistance and fruit-pathogen interactions to develop safer strategies for the sustainable control of P. digitatum and P. italicum in citrus.

“…The main mechanism by which HWTs limit the infection process is the disinfection of fruit specimens (removing fungal spores from surfaces; Pavoncello et al., 2001). In addition, HWTs interrupt the growth of fungal spores remaining on fruit surfaces for more than 24 h. Similarly, the heat of hot water stimulates the production of secondary metabolites, including phytoalexins, pathogenesis‐related proteins, and heat shock proteins involved in fruit resistance to fungi (Perotti et al., 2015; Sui et al., 2016). Lignin accumulation is promoted by HWT in infected fruit and acts as a barrier against fungal infection, limiting the fruit from prolonged decomposition (Yun et al., 2013).…”

Fruit‐based diets have been adopted by the public worldwide because of their nutritional value. Many advances have also been made in the elucidation of host–pathogen interaction in the postharvest phase of fruits, in the hope of improving the management of diseases caused by pathogenic molds. In this study, we presented the molecular mechanisms by which pathogenic mold infects fruit in the postharvest phase, and focused on the knowledge gained from recent molecular techniques such as differential analysis of gene expression, targeted insertion, and mutagenesis. Current postharvest pathogenic fungal control strategies were then examined on the basis of their mechanisms for altering the infection process in order to explore new perspectives for securing fruit production. We found that biotechnological advances have led to an understanding of the new basic molecular processes involved in fruit fungal infection and to the identification of new genes, proteins and key factors that could serve as ideal targets for innovative antifungal strategies. In addition, the most commonly used steps to evaluate an approach to disrupt the fruit fungal infection process are mainly based on the inhibition of mycelial growth, spore germination, disruption of Adenosine triphosphate (ATP) synthesis, induction of oxidative stress, cell wall membrane damage, and inhibition of key enzymes. Finally, the alteration of the molecular mechanisms of signaling and response pathways to infection stimulation should also guide the development of effective control strategies to ensure fruit production.
