seedling AtGLDH mRNA level exhibits diurnal change. The level is low in the morning and increases during the day. Its level at 18.00 is about 2fold that in the morning at 6.00. Then the level decreases during the night until dawn of the next day. The diurnal change is regulated by light Arabidopsis thaliana
