Prunus persica Transcriptome or Gene expression. Prunus persica

Peach, which has flavorful aroma, is a popular and economically important fruit crop worldwide. However, because of the absence of efficient genetic resistance, most peach cultivars suffer from the destructive gummosis disease in high temperature and humidity areas, such as Japan, south of China and USA. Fungal peach gummosis is mainly caused by Botryosphaericeae pathogens. In this study, the genome-wide PpTPS genes were identified and clustered into different classes. An approach combining non-targeted metabolomics based on ultra-high performance liquid chromatography-mass spectroscopy, gas chromatography-mass spectroscopy and transcriptome was performed, the aim is to investigate the potential roles of PpTPS genes and terpenes in defense responses of peach plants to pathogens and in the formation of fruit floral-note compounds.
