The Five AhMTP1 Zinc Transporters Undergo Different Evolutionary Fates towards Adaptive Evolution to Zinc Tolerance in Arabidopsis halleri
Figure 7
AhMTP1s transcript accumulation in plants submitted to different zinc treatments.
Roots and shoots were collected from plants of the A. halleri SAF2 genotype issued from the Auby accession that were exposed to 10 (control), 100, 300, or 1000 µM ZnSO4 for 4 days. Real-time quantitative RT–PCR was performed using gene copy specific primer pairs separately for shoots and roots. Data shown are transcript levels of AhMTP1s relative to Actin. Each data point in the graph is the average of three PCR repetitions for each of six biological replicates. Errors bars correspond to confidence intervals at the 0.05 threshold.
