Expression

Organism Comment Expression
Amaranthus hypochondriacus when examined at 06.00 h and 15.00 h during different months of the year, the activity of PEPC is maximal in summer (e.g. May) and minimal in winter (e.g. December). The maximum activity of PEPC is at 15.00 h during a typical day in all months up
