TL;DR: Although trichloroacetic acid had no effect on synthesis of fatty acids by either seed, other compounds such as decenylsuccinic acid and carbamate weed killers specifically reduce the formation of the very long chain fatty acidsby pea thus suggesting a mode of action for these compounds in wax formation.

TL;DR: Electron microscopy of the isolated oil droplets and the seed tissue in vivo revealed particulate containing vacuole-like inclusions which, it is suggested, are the site of lipid synthesis and which form the original locus of the droplet.
Abstract: Fat droplets isolated from maturing castor bean seeds contain high concentrations of fatty acid synthetase and triglyceride synthesizing enzymes. These activities are not due to contamination by other organelles and account for at least 80% of the total lipid synthesis. Electron microscopy of the isolated oil droplets and the seed tissue in vivo revealed particulate containing vacuole-like inclusions which, it is suggested, are the site of lipid synthesis and which form the original locus of the droplet.
