Apple russeting as seen through the RNA-seq lens: strong alterations in the exocarp cell wall

ABSTRACT: Russeting is a commercially important defect in apple (Malus x domestica) fruit production. Apple russeting is mainly characterized by the accumulation of suberin on the inner part of the cell wall. However, knowledge on the underlying genetic components triggering this trait remains sketchy. A bulk transcriptomic profiling was performed on the exocarps of three russeted and three waxy apple varieties using RNA sequencing. This experimental design was chosen to lower the specificities of each genotype. A qPCR validation was carried out on representative genes and additional contrasting varieties. Gene ontology enrichment revealed a repression of the lignin and cuticle biosynthesis genes in the russeted exocarps, concomitantly with an enhanced expression of suberin deposition, stress respon
