Description
| - 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 tube growth in a dose-dependent manner, while N-nitro-L-arginine (L-NNA) and cPTIO inhibited NO production and arrested pollen tube growth. Noninvasive detection and microinjection of a Ca2+ indicator revealed that SNAP promoted extracellular Ca2+ influx and increased the steepness of the tip-focused Ca2+ gradient, while cPTIO and L-NNA had the opposite effect. Fluorescence labeling indicated that SNAP, cPTIO and L-NNA altered actin organization, which subsequently affected vesicle trafficking.
