Abstract

Phosphoinositides play an important role in both abiotic and biotic signalling in plants. The signalling cascade may include the production of second messengers by hydrolysis of PtdIns(4,5)P₂. However, increasingly, PtdIns(4,5)P₂ itself is shown to mediate signalling by regulating target proteins. The present mini-review summarizes the experimentally demonstrated effects of PtdIns(4,5)P₂ on plant K ⁺ channels and examines their structure for candidate sites of direct PtdIns(4,5)P₂-protein interaction.
