The effect of CPPU on volatile compounds and transcriptome analysis of 'Shine Muscat' berries

Grape volatiles include a great number of compounds, among which monoterpenes, alcohols,esters and carbonyls were found.Grape may be divided into aromatic and non-aromatic varieties. 'Shine Muscat' belongs to the aromatic cultivar. The most abundant free compounds detected in Muscat grape were linalool, geraniol, citronellol, nerol. Grapevine (Vitis vinifera L.) is an economically important and widely cultivated fruit crop. Grape quality is important for its market value and is largely decided by its taste and aroma.Gas-chromatograph mass-spectrometry (GC-MS) was performed to observe changes of the volatile compounds. Overall design: Three treated samples (CPPU 0, CPPU 5ppm and CPPU 10 ppm) of grapevine were selected, and total RNA was extracted from these samples for further library construction.
