Apple MdMYC2 reduces aluminum stress tolerance by directly regulating MdERF3 gene

Background and aims Jasmonate (JA) and ethylene are involved in the regulation of the aluminum (Al)-induced growth inhibition. Although it has been reported that JA enhances Al-induced root-growth inhibition, its role in the regulation of growth interplaying with ethylene is still not well understood. In this study, we investigated the mechanism underlying the effect of apple MdMYC2 transcription factor on Al stress.
