From: Fruit volatilome profiling through GC × GC-ToF-MS and gene expression analyses reveal differences amongst peach cultivars in their response to cold storage

Multi-trait analysis of expression genes from LOX pathway and 63 associated LOX pathway VOCs in the six peach cultivars before and after cold storage (a) Heat map of WCNA modules with scores and significance (P values in brackets) based on a Pearson analysis; (b–d) linear discriminant plots from Canonical Analysis of Principal coordinates (CAP) based on 16 VOCs selected from WCNA analysis of LOX gene expression versus LOX related VOCs from six peach cultivars: ‘Sagittaria’, ‘Big Bang’, ‘Big Top’, ‘Carene’ ‘Rome star’ and ‘Summer Rich’, by (b) cultivar, (c) peach versus nectarine, (d) the six peach cultivars analysed before (D0, in red) and after (D7, in blue) a 7 day storage period at 1 ℃ followed by a 36 h shelf life storage at 20 ℃. (mean + SE). Each ellipse represents the 95% confidence interval of SE. The plots use LD1 (b) with a percentage of correct classification = 83% (P = 0.01; n = 6); (c) 97% (P = 0.01; n = 18); (d) 72% (P = 0.9; n = 3).
