Highlights

  • Fruit ripening is an essential plant trait for plant shelf life at the commercial level.

  • Transcription factors and phytohormones are important in apple ripening.

  • Flavonoid-anthocyanin biosynthesis pathway involved in red pigmentation in apple.

  • Genes contributing to the Plant hormone signal transduction pathway are involved in the fruit ripening process.

Abstract

Fruit development and ripening are essential components of human and animal diets. Fruit ripening is also a vital plant trait for plant shelf life at the commercial level. In the present study, two apple cultivars, Hanfu wild (HC) and Hanfu mutant (HM), were employed for RNA-Sequencing (RNA-Seq) to explore the genes involved in fruit ripening. We retrieved 2642 genes, differentially expressed in HC and HM apple cultivars. Gene ontology (GO) analysis revealed the 569 categories, significantly enriched in biological process, cellular component, and molecular function. KEGG analysis exhibited the plant hormone transduction and flavonoid-anthocyanin biosynthesis pathways, might be involved in the fruit ripening and anthocyanin biosynthesis mechanism. A cluster of 13 and 26 DEGs was retrieved, representing the plant hormones and transcription factors, respectively, that may be important for early ripening in HM genotype. This transcriptome study would be useful for researchers to functionally characterize the DEGs responsible for early ripening.
