Additional file 4. Phenotypic analysis of F. × ananassa “Chandler” in vitro plants grown in N30K medium supplemented with hormones. (A) General view of control plants (CONTROL) and treated plants with gibberellic acid (GA3) and paclobutrazol (PBZ) after 11 dpt. Analysis by qRT-PCR of FaPRE1, FaPRE2 and FaPRE3 expression in leaves (B), pedicels (C) and roots (D) from in vitro strawberry plants (F. × ananassa “Chandler”) treated with GA3 and PBZ. Mean values ± SD of three independent experiments are shown. CONTROL, plants in N30K medium; GA3, plants in N30K medium supplemented with GA3 100 μM; PBZ, plants in N30K medium supplemented with paclobutrazol 100 μM. Statistical significance with respect to the reference sample (Control) was determined by the Student’s t-test: *p
