“…(Toivonen and Brummell, 2008), and all these events potentially influence the dynamics of the fruit microbiome. Sustained low temperatures during storage can also exert a profound effect on fruit microbiome dynamics, with previous studies reporting a general decrease in diversity and fluctuations in the relative abundance of microbial taxa in stored apples (Bösch et al, 2021). As such, incorporating information of these fruit physiological parameters and their influence on the fruit microbiome will provide a more comprehensive picture of the factors shaping the ecology and dynamics of fruit-associated microbiome, and we acknowledge the lack of this information as a limitation in the present study.…”

“…The fruit surface of the domesticated apple ( Malus × domestica Borkh.) has been reported to be naturally colonized by numerous microbes that vary in abundance and diversity according to host genotype, geographical location, management practices, and fruit tissue type ( Wassermann et al, 2019a , b ; Abdelfattah et al, 2020 , 2021 ; Bösch et al, 2021 ). Little is known, however, about the ecological processes, particularly with regard to selection, that regulate temporal carposphere microbial dynamics.…”

Microbial communities associated with fruit can contribute to quality and pathogen resistance, but little is known about their assembly and dynamics during fruit development and storage. Three apple cultivars growing under the same environmental conditions were utilized to examine the apple carposphere microbiome composition and structure at different developmental stages and storage. There was a significant effect (Adonis, p ≤ 0.001) of fruit genotype and its developmental stages and storage times on the fruit surface microbial assemblage and a strong temporal microbial community succession was detected (Mantel test: R ≤ 0.5, p = 0.001) in both bacterial and fungal communities. A set of 15 bacterial and 35 fungal core successional taxa and members exhibiting differential abundances at different fruit stages were identified. For the first time, we show the existence of underlying universal dynamics in the assembly of fruit-associated microbiomes. We also provide evidence of strong microbial cross-domain associations and uncover potential microbe-microbe correlations in the apple carposphere. Together our findings shed light on how the fruit carposphere assemble and change over time, and provide new insights into fruit microbial ecology.

The maintenance of the beneficial plant microbiome to control plant pathogens is an emerging concept of disease management, and necessitates a clear understanding of these microbial communities and the environmental factors that affect their diversity and compositional structure. As such, studies investigating the microbiome of economically significant cultivars within each growing region are necessary to develop adequate disease management strategies. Here, we assessed the relative impacts of growing season, management strategy, and geographical location on the fungal microbiome of 'Honeycrisp' apples from seven different orchard locations in the Atlantic Maritime Ecozone for two consecutive growing years. Though apple fruit tissue was dominated by relatively few fungal genera, significant changes in their fungal communities were observed as a result of environmental factors, including shifts in genera with plant-associated lifestyles (symbionts and pathogens), such as Aureobasidium, Alternaria, Penicillium, Diplodia, and Mycosphaerella. Variation in fungal composition between different tissues of fruit was also observed. We demonstrate that growing season is the most significant factor affecting fungal community structure and diversity of apple fruit, suggesting that future microbiome studies should take place for multiple growing seasons to better represent the host-microbiome of perennial crops under different environmental conditions.

“…It is interesting to note that metabolites released by the fruits could modulate the diversity of the microbiome (Miguel et al, 2013). Hot-water treatment (HWT) is used at postharvest stage in certain crops to reduce pathogen infections and prolong shelf life (Bösch et al, 2021;Li et al, 2013;Papoutsis et al, 2019;Singh & Sharma, 2018;Zhang et al, 2017). The influence of HWT on the microbiome of stored apples was studied by Wassermann, Kusstatscher, et al (2019).…”

“…This indicates the need for cold packing of apples in a limited time to reduce the risk of adverse health effects to consumers. Washing and waxing procedures were also reported to influence the microbiome organization of the fruits (Bösch et al., 2021). Further research is expected to confirm these findings on different fruits (Shen et al., 2018).…”

Fruit-based diets are recognized for their benefits to human health. The safety of fruit is a global concern for scientists. Fruit microbiome represents the whole microorganisms that are associated with a fruit. These microbes are either found on the surfaces (epiphytes) or in the tissues of the fruit (endophytes). The recent knowledge gained from these microbial communities is considered relevant to the field of biological control in prevention of postharvest fruit pathology. In this study, the importance of the microbiome of certain fruits and how it holds promise for solving the problems inherent in biocontrol and postharvest crop protection are summarized. Research needs on the fruit microbiome are highlighted. Data from DNA sequencing and "meta-omics" technologies very recently applied to the study of microbial communities of fruits in the postharvest context are also discussed. Various fruit parameters, management practices, and environmental conditions are the main determinants of the microbiome. Microbial communities can be classified according to their structure and function in fruit tissues. A critical mechanism of microbial biological control agents is to reshape and interact with the microbiome of the fruit. The ability to control the microbiome of any fruit is a great potential in postharvest management of fruits. Research on the fruit microbiome offers important opportunities to develop postharvest biocontrol strategies and products, as well as the health profile of the fruit.
