Metabolomic dataset of an apple progeny carrying resistance quantitative trait loci to apple scab without or after inoculation of the pathogen Venturia inaequalis

The development of new varieties combining complementary molecular mechanisms is hypothesized to enhance the durability of genetic resistance to apple scab. However, both the underlying mechanisms and the efficiency of their pyramiding are still unknown. To further understand the molecular mechanisms of resistance to the fungus Venturia inaequalis (responsible of apple scab), we explored apple specialized metabolism through an untargeted metabolomic approach of a pseudo-F1 progeny, known as the ‘TxF progeny’. This progeny was previously widely investigated for its favourable resistance alleles and four segregating quantitative trait loci (QTL) were described. To identify metabolites associated with resistance conferred by each QTL, a total of three experiments have been conducted in a greenhouse environment on this progeny. The datasets include raw metabolomic profile descriptions of three experiments with or without experimental inoculation of Venturia inaequalis.

人们推测，结合互补分子机制培育的新品种可提升苹果黑星病遗传抗性的持效性。然而，其背后的分子机制以及抗性堆叠的效率仍未明确。为进一步解析苹果黑星病致病菌（Venturia inaequalis，引发苹果黑星病的真菌）的抗性分子机制，我们针对一种名为‘TxF后代群体’的假F1后代群体，采用非靶向代谢组学分析方法探究苹果的特化代谢通路。该群体此前已被广泛研究其优良抗性等位基因，且已有4个分离的数量性状位点（QTL）被报道。为鉴定与每个QTL介导的抗性相关的代谢物，研究团队基于该后代群体在温室环境中开展了共计3组实验。本数据集包含3组分别接种与未接种苹果黑星病致病菌（Venturia inaequalis）的实验的原始代谢组谱数据。
