Upregulation of polyphenol-related genes prevents ‘skin burning’ of well-colored ‘Cameo’ apples stored under stressful controlled atmosphere conditions
چکیده انگلیسی

‘Skin burning’ of ‘Cameo’ apples resulting in poorly colored fruit can occur in storage under high CO2 condition. To elucidate possible reasons for this physiological disorder, we assessed the differential expression of polyphenol-related genes. Poorly colored and well-colored mature ‘Cameo’ apples were stored under either high (3%) or low (0.7%) CO2 levels, both in combination with 1% O2, and monitored for seven months for ‘skin burning’. Samples were obtained by the end of storage period, and qPCR analyses were conducted using gene specific primers. We found expression levels of chalcone synthase (MdCHS), chalcone isomerase (MdCHI), anthocyanidin synthase (MdANS), flavonol synthase (MdFLS), dihydroflavonolreductase (MdDFR), and leucoanthocyanidinreductase (MdLAR1) genes to be substantially higher in well-colored compared to poorly colored apples. The delay in establishing the stressful controlled atmosphere (CA) storage condition (3% CO2 level) led to significantly higher expression levels of MdLAR1, MdCHI, anthocyanidinreductase (MdANR) and flavanone 3-hydroxylase (MdF3H), which may explain the lower incidence of ‘skin burning’ by delayed CA fruit. On the other hand, after seven months in storage, the expression levels of phenylalanine ammonia-lyase (MdPAL), MdCHS, MdCHI, MdDFR, MdFLS, and MdF3H, were significantly higher in poorly colored injured apples, which reflect a feedback mechanism to synthesize more polyphenols to counteract the stressful storage condition.


► Poorly colored ‘Cameo’ apples suffer from ‘skin burning’.
► Storage of ‘Cameo’ apples at high CO2 level leads to severe ‘skin burning’.
► Polyphenols-related genes are directly involved in development of ‘skin burning’.
► Delayed storage of fruits at high CO2 level reduces the severity of ‘skin burning’.
