“…The hypothesis was formulated that the patulin formation in 2015 could be related to differences in weather conditions in 2015 and 2016. Spotts et al (2009) have stated that rainfall during or just before harvest may increase the risk of post-harvest decay; therefore the sum of precipitation and average temperature two weeks before harvest of each apple cultivar was analysed. It was revealed that in Danish and Estonian orchard locations, the harvest season in 2016 was a lot drier and warmer compared to the 2015 season when patulin was found in juice (Table 3).…”

The aims of this study were to find out if organic apple juice (AJ) contained higher contents of polyphenols or patulin compared to conventional AJ, and if higher storage temperature before processing increases patulin content in juice. AJ was pressed from Estonian, Danish and Norwegian apples. Additionally, three cultivars from Estonian organic and conventional orchards were stored at 3±2 °C and 9±2 °C before processing. Patulin, polyphenol content and antioxidant capacity were determined in pasteurized juices. In 2015, 33% of conventional (n=6) and 46% of organic (n=11) juices contained patulin; two of the organic juices above the legal limit (191 and 64µg l-1). In 2016, none of the AJs contained patulin. Patulin occurrence was more affected by weather conditions two weeks before harvest than by cultivation system and apple storage temperature. Polyphenol content was higher in organic than in conventional juices and was reduced at higher apple storage temperature.

“…Grey mould disease is one of the most serious postharvest diseases of apple and is caused by Botrytis cinerea (Batta, ), which is a ubiquitous fungal pathogen that is spread in many ways. Botrytis cinerea conidia from weeds, fallen fruit and many other host plants are easily spread by air, water and insects (Spotts et al., ). Although apple fruits may be infected by B. cinerea at harvest or earlier, grey mould disease usually develops during the postharvest stage (Batta, ).…”

The phenylpropanoid pathway affects apple fruit resistance to Botrytis cinerea

Apple fruits are rich in phenolic compounds that may enhance resistance to grey mould disease caused by Botrytis cinerea. Using Malus domestica Borkh. cultivars Fuji and Qinguan, we analysed the contents of total phenols, total flavonoids, eight individual phenolic compounds, H2O2 and O2.− as well as the activities of key enzymes in the phenylpropanoid pathway in the flesh of control and B. cinerea‐inoculated fruits. Chlorogenic acid contents increased for a short period in the less susceptible cultivar Qinguan fruits, but decreased in the disease‐susceptible Fuji fruits. Additionally, ferulic acid production was induced in both cultivars in response to B. cinerea. Furthermore, the activities of phenylalanine ammonia lyase, cinnamate 4‐hydroxylase, 4‐coumarate:coenzyme A ligase and cinnamyl alcohol dehydrogenase were differentially induced between the two apple cultivars. Remarkably, the contents of H2O2 and O2.− as well as the activities of enzymes in phenolic metabolism tested in this study were always higher in Qinguan fruits than in Fuji fruits. Our data imply that phenylpropanoid metabolism is closely associated with apple fruit resistance to grey mould disease. These findings may be useful for characterizing the mechanism(s) underlying plant resistance to B. cinerea, with potential implications for the screening of grey mould disease‐resistant apple varieties in breeding programmes.

For some applications (for example, detection of Botrytis in grape juice), testing is carried out at the end of the decay process; however, for other applications testing is necessary in the early stages of infection, such as prior to storage of fruit or other commodities (Spotts et al. 2009).…”

“…Immunological and nucleic acid-based methods have been developed for the detection of B. cinerea (Bossi and Dewey 1992;Rigotti et al 2002;Dewey and Meyer 2004;Suarez et al 2005;Spotts et al 2008;Celik et al 2009). For some applications (for example, detection of Botrytis in grape juice), testing is carried out at the end of the decay process; however, for other applications testing is necessary in the early stages of infection, such as prior to storage of fruit or other commodities (Spotts et al 2009). Nucleic acid-based methods have been successful in the detection of B. cinerea in presymptomatic infection (Suarez et al 2005;Celik et al 2009).…”

Aims: To develop a sensitive, rapid and simple method for detection of Botrytis cinerea based on loop‐mediated isothermal amplification (LAMP) that would be suitable for use outside a conventional laboratory setting. Methods and Results: A LAMP assay was designed based on the intergenic spacer of the B. cinerea nuclear ribosomal DNA (rDNA). The resulting assay was characterized in terms of sensitivity and specificity using DNA extracted from cultures. The assay consistently amplified 65 pg B. cinerea DNA. No cross‐reactivity was observed with a range of other fungal pathogens, with the exception of the closely related species Botrytis pelargonii. Use of a novel real‐time LAMP platform (the OptiGene Genie I) allowed detection of B. cinerea in infected rose petals, with amplification occurring in <15 min. Conclusions: The LAMP assay that was developed is suitable for rapid detection of B. cinerea in infected plant material. Significance and Impact of the Study: The LAMP method combines the sensitivity and specificity of nucleic acid‐based methods with simplified equipment and a reduced reaction time. These features make the method potentially suitable for on‐site use, where the results of testing could help to inform decisions regarding the storage and processing of commodities affected by B. cinerea, such as cut flowers, fruit and vegetables.
