Lipid droplets, dynamic organelle in germinating seeds that gives a versatile emulsion

Abstract

Results from a detailed study of LDs from seeds of several B. napus accessions with contrasted oil extractability suggest that the protein and lipid compositions of the half membrane of LDs affect their rigidity (1,2). We have deciphered the topology of structural proteins at the surface of LDs (3). We followed the digestibility of LDs using an in vitro model digestor mimicking different compartments. While seed LDs are quiescent in dry seeds, their structure and composition rapidly evolve during seed germination. We have identified a novel mechanism controlling LD dynamics and required to remove the oleosin coat that stabilizes LDs in dry seeds (4, 5). It seems to us necessary to consider new methods of seed fractionation and extraction of oil taking into account the living nature of seeds. Water based extraction is an alternative to existing processes using a lot of energy and organic solvents.
