Relative mRNA levels of VDL1, VDL2 and VDE detected by real-time quantitative PCR a, growth b, and photosynthetic efficiency (Fv/Fm) c of wild-type (Pt1 and/or Pt6) and VDL1 overexpression (OE) strains. Allele 1 and allele 2 represent the VDL1 alleles 1 and 2, respectively. Different letters above the bars indicate statistically significant differences (P < 0.05)
