Nitric oxide modulates the influx of extracellular Ca2+ and actin filament organization during cell wall construction in Pinus bungeana pollen tubes

Effects of nitric oxid (NO) on extracellular Ca2+ flux and actin microfilaments were investigated during cell wall construction in Pinus bungeana pollen tubes. NO donor S-nitroso-N-acetylpenicillamine (SNAP) enhanced pollen...
