Fig. 2From: Determination of superior Pistacia chinensis accession with high-quality seed oil and biodiesel production and revelation of LEC1/WRI1-mediated high oil accumulative mechanism for better developing woody biodieselVariabilities on seed oil content and oil body amount of 5 selected germplasm accessions of P. chinensis. a Variability on seed oil content from different accessions. b Observation of lipid droplet on both longitudinal and transverse sections of the seeds from accession PC-HN colored by safranin with fast green. c Observation of lipid droplet on both longitudinal and transverse sections of the seeds from accession PC-BJ colored by safranin with fast green. d Observation of lipid droplet on both longitudinal and transverse sections of the seeds from accession PC-AH colored by safranin with fast green. e Observation of lipid droplet on both longitudinal and transverse sections of the seeds from accession PC-SX colored by safranin with fast green. f Observation of lipid droplet on both longitudinal and transverse sections of the seeds from accession PC-HN colored by safranin with fast green. g Variability on the scanned density of lipid droplet in transverse section among different accessions. h Variability on the scanned density of lipid droplet in longitudinal section among different accessions. Error bars are standard deviations (SD) of three biological replicates, and the statistical results are presented in Additional file 1: Table S1Back to article page
