Enhancement of chlorophyll a fluorescence yield, low-temperature F685/F730 fluorescence emission ratio, and electron transport rate by ether phospholipids (platelet activating factor and analogs) in isolated chloroplasts.


Acetyl glyceryl ether phosphorylcholine (1-O-alkyl-2-acetyl-sn-glyceryl-3-phosphorylcholine; or platelet activating factor (PAF)), when incubated with chloroplasts or subchloroplast fractions derived from stroma or grana lamellae, induces a drastic increase in the low-temperature fluorescence emission ratio F685/F730 (77 degree K). The molecular structure… (More)
