Abstract
Uptake of phosphate in Chara occurs through 2 systems, one with a high affinity (Km approximately 3 µM) and another with a much lower affinity (Km about 100 µM). The activity of the high affinity system increases with starvation in Pi-free solution up to 6 d. This high affinity system requires Na; the Km for Na for the stimulation of Pi uptake is approximately 200 µM. Influx of Na is also increased in the presence of Pi which suggests a mechanism in which Na and P are co-transported.
