Relative expression level of sugar metabolic gene in apple calli infiltrated with MdSUT4.1 (black column) and the entry vector pSAK277 (control, gray column). Statistical significance was analyzed by Student’s t-test. **, P < 0.01; *, P < 0.05; NS, no significant difference (P > 0.05). Error bars represent SE of three biological replicates. SPS, sucrose phosphate synthase; SDH, sorbitol dehydrogenase; vAINV, vacuolar acid invertase; NINV, neutral/cytosol invertase; CWINV, cell wall invertase; SUSY, sucrose synthase
