Thin-layer chromatography analysis revealed that the contents stored in oil bodies isolated from jelly fig (Ficus awkeotsang Makino) achenes were mainly neutral lipids (> 90% triacylglycerols and similar to 5% diacylglycerols). Fatty acids released from the neutral lipids of achene oil bodies were highly unsaturated (62.65% alpha-linolenic acid, 18.24% linoleic acid, and 10.62% oleic acid). The integrity of isolated oil bodies was presumably maintained via electronegative repulsion and steric hindrance provided by their surface proteins. Immunological cross-recognition using antibodies against sesame oil-body proteins indicated that two oleosin isoforms and one caleosin were present in these oil bodies. MALDIMS analyses confirmed that the three full-length cDNA fragments obtained by PCR cloning from maturing achenes encoded the two jelly fig. oleosin isoforms and one caleosin identified by immunological screening.
