Periodic Increases in Elongation Rate Precede Increases in Cytosolic Ca super(2+) during Pollen Tube Growth

Pollen tubes grown in vitro require an intracellular tip-high gradient of Ca super(2+) in order to elongate. Moreover, after about 2 h in vitro both the tip Ca super(2+) and the elongation rate of lily tubes begin to oscillate regularly with large amplitudes. This raises the question of the phase re...
