Expression of the predicted active MAPK cascade and transcription factor genes in the space-grown Mizuna by qRT-PCR. Expression levels of the predicted active genes, OXI1, MEKK1, MKK4, MPK3, Zat12, WRKY22 and WRKY25 in the space-grown and the ground-grown Mizuna were analyzed by qRT-PCR. Expression levels of genes in the space-grown and the ground-grown Mizuna were normalized with that of the α-tubulin gene as an internal control. The error bar represents standard error of the mean for three RNA isolation experiments.
