Molecular Species Composition of Phosphatidylglycerol in Leaves of Camellia Species and Chilling Sensitivity
MGDG isolated from chloroplast thylakoid of camellia species was 18: 3 and this fatty acid accounted for 90% of fatty acid constituents of MGDG. PG showed characteristic fatty acid composition; 16: 0, (3E)-16: 1 and 18: 1 were major fatty acids. (3E)-16: 1 attached to C-l position of PG and 18: 1 to C-1. Major molecular species of PG was 1-18: 1-2-(3E)-16: 1-PG. This molecular species accounted for 40–70% in tea leaves and showed seasonal dependent change.
