To russet or not to russet: MdMyb93 as a regulator of suberin deposition in apple fruits

ABSTRACT: • A comparison of the transcriptomes of russeted vs. waxy apple exocarps previously highlighted a tight relationship between a gene encoding a MYB-type transcription factor, MdMYB93, and some key suberin biosynthetic genes. The present work assesses the role of this transcription factor in the suberization process. • A phylogenetic analysis of MdMYB93 and Arabidopsis thaliana MYBs was performed and the function of MdMYB93 was further investigated using Agrobacterium-mediated transient overexpression in Nicotiana benthamiana leaves. An RNA-Seq analysis was performed to highlight the MdMYB93-regulated genes. UPLC-TripleTOF and GC-MS were used to investigate alterations in phenylpropanoid, soluble free lipid, and lipid polyester contents. • A massive accumulation of suberin and its bi
