Differential metabolites detected between the thermotolerant lettuce seeds germinated at 21 °C and 35 °C. Note: The heatmap indicates the differential metabolites detected between buds of S15k0106 seeds germinated at 21 °C (C106) and 35 °C(HY106). A red box means that most of the metabolites in this class had higher relative abundances in HY106 compared to those in C106, while a blue box represents that relative abundances of most of the metabolites in this class were lower in C106 than those in HY106; a gray box denotes no significance between C106 and HY106.
