Other claims from this paper (6)
- Observation A hyperpolarization-activated Ca2+-permeable channel was identified on the plasma membrane of Lilium davidii pollen protoplasts.
- Intervention effect Trivalent cations, verapamil, nifedipine or diltiazem suppressed the hyperpolarization-activated Ca2+-permeable channel of Lilium davidii pollen protoplasts.
- Intervention effect Calmodulin antiserum and W7-agarose, both cell-impermeable CaM antagonists, decreased cytosolic Ca2+ concentration in Lilium davidii pollen.
- Intervention effect Exogenous purified CaM transiently increased cytosolic Ca2+ concentration in Lilium davidii pollen.
- Intervention effect Exogenous purified CaM activated the hyperpolarization-activated Ca2+ conductance of pollen protoplasts in a dose-dependent manner.
- Intervention effect EGTA or Ca2+ channel blockers inhibited the increase of [Ca2+]c and the activation of Ca2+ conductance induced by exogenous CaM in Lilium davidii pollen.
