The relationship of Ca2+ and plasmodesmatal closure was examined in staminal hairs of Setcreasea purpurea by microinjecting cells with active mastoparan (Mas-7), inactive mastoparan (Mas-17), active inositol-1,4,5-trisphosphate (IP3), or inactive IP3. Calcium green dextran 10,000 was used to study cellular free Ca2+, and carboxyfluorescein was used to monitor plasmodesmatal closure. When Mas-7 was microinjected into the cytoplasm of cell 1 (the tip cell of a chain of cells), a rapid increase in… CONTINUE READING
