2.4.1.123 leaf in leaves of Arabidopsis thaliana plants overexpressing heat shock transcription factor A2, the transcription of GolS1, -2, and -4 and raffinose synthase 2 (RS2) is highly induced. In leaves of the wild-type plants, treatment with 50 mM methylviologen increases the transcript levels of GolS1, -2, -3, -4, and -8 and the total activities of GolS isoenzymes Arabidopsis thaliana
