Expression profiles of Medicago truncatula ABCG59, ABCG43, and ABCG44. (A, B) Quantitative Real-Time PCR expression analysis of MtABCG59, MtABCG43, and MtABCG44 in roots under phosphate-limiting conditions (A) or treated with the synthetic strigolactone analogue rac-GR24 (B). The transcript levels were normalized to the actin gene from Medicago truncatula. Data represent the mean ± SD of three and four independent biological experiments, respectively, and three technical repeats. Significant differences from the control plants determined by Student's t-test are indicated as follows: *P < 0.05, **P < 0.01, ***P < 0.001.
