Like plant leaves, suspension cultures of photoautotrophic Oxy basis rubra Fuentes-Bazan (syn. Chenopodium rubrum L.) cells pass through distinct developmental phases when grown under CO2 as the sole carbon source: an initial cell division phase of 4 weeks, a stationary phase of another 4 weeks and an aging phase (3-4 weeks) when the cell senesce and finally die. These phases are reflected by differential gene expression.
