Apple production is threatened by cadmium contamination in orchards. Cd accumulation and tolerance in grafted Malus plants is affected by rootstock, scion, and their interaction. This dataset is part of an experiment investigating the molecular mechanism of Cd bioaccumulation and tolerance in different apple rootstock-scion combinations. We exposed four rootstock-scion combinations to Cd treatment consisting of Hanfu and Fuji apple (Malus domestica) scions grafted onto apple rootstocks of M. baccata or M. micromalus "qingzhoulinqin". RNA sequencing was conducted in roots and leaves of grafting combinations under 0 or 50 μM CdCl conditions. A comprehensive transcriptional dataset of affected rootstock, scion, and their interaction among different graft combinations was obtained. This dataset provides new insights in the transcriptional control of Cd bioaccumulation and tolerance in grafting plants regulated by rootstock and scion. Herein, we discuss the molecular mechanism underlying Cd absorption and bioaccumulation.
苹果生产受到果园中镉污染的威胁。接穗和砧木及其相互作用影响嫁接在苹果植株中的镉积累和耐受性。本数据集是一项研究不同苹果砧木-接穗组合中镉生物积累和耐受性分子机制的实验的一部分。我们将四种砧木-接穗组合暴露于含有 Cd 的处理中，处理组由 Hanfu 和 Fuji 苹果（Malus domestica）接穗嫁接在苹果砧木 M. baccata 或 M. micromalus “qingzhoulinqin”上组成。在 0 或 50μM CdCl 条件下对嫁接组合的根和叶进行 RNA 测序。获得了不同嫁接组合中受砧木、接穗及其相互作用影响的综合转录数据集。该数据集为受砧木和接穗调控的嫁接植物中 Cd 生物积累和耐受性的转录控制提供了新的见解。在此，我们讨论了 Cd 吸收和生物积累的分子机制。
