Abstract
The molecular mechanisms of plant hormone action involve different processes playing a basic role in cell life. Among them are processes controlling intracellular pH value and activity of Cl--transporters of plasma membrane (Taiz and Zeiger, 1998). Here we show that intracellular pH (pHi) and Cl- transport across plasmalemma may be the controlling factors in differentiation and germination of Angiosperm pollen grain. Until now ionic mechanisms regulating pollen grain development are practically unknown. The attention in this field is focused mainly on the role of Ca2+ in signaling (Frankling-Tong, 1999). Cl- dynamics was characterized only during apical growth of a pollen tube (Zonia et. al., 2001).
