Apple gene model is based on available Malus_x_domestica.v3.0.a1_gene_set at https://www.rosaceae.org. Function annotation is based on the blastX search against NR database in GenBank. Variations of transcript abundance are based on the comparison between B.9 and G.935 and expressed as Log₂fold change. + indicated higher transcript level in the root of G.935 over that in B.9; − indicated the opposite.
