Arabidopsis ecotype Ws-2 and heterozygous +/gpt1-1 and +/gpt1-2 T-DNA lines compared to plastid-compensated GPT1 gpt1-2::ProMAS:GPT2 or::ProGPT1:GPT2 lines (T2 generation) and ER/peroxisomal-compensated line::Pro35S:GFP-GPT1_C-mat (T3 generation). Transformed progenies were initially selected on Hygromycin B. Values (bold) are given in percent.
