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.
