Intriguing that each oil bodies and protein bodies have been observed in the cells with the aleuronic layer (Fig. 1C), which has not been reported in previous research. At the same time, oil bodies and protein bodies had been also observed in radicle cells and cotyledon cells (Fig. 1D, 1E). In the mature dry seeds, the cytoplasm of your cotyledon cells, radicle cells and aleuronic cells was totally filled with oil bodies and protein bodies. Nevertheless, the oil body organelles comprised 81 with the total cell area inside the cotyledon cells, only 50 in the aleuronic cells and 35 in the radicle cells (Table 1). All oil bodies were spherical in shape, ranging in sizePLOS A single | plosone.orgComparative Evaluation of Fatty Acid Composition in Distinct Oil Content material Rapeseed LinesLipids are frequently stored as triacylglycerols in oil bodies. Although you will discover quantitative variations inside the accumulation of storage reserves in seeds, it was not clear no matter if this would also qualitatively impact the fatty acid profiles of triacylglycerols in these seeds. Hence, fatty acid compositions in these seven rapeseed lines had been measured. As shown in Fig. six, the results recommended there have been two primary sorts with either a higher or maybe a low C22:Seed Structure of Ultrahigh Oil Content material RapeseedFigure 1.

The C22:1 content of the ultrahigh oil content material line, YN171, and a single higher oil content material line, 09?eight, were more than 35 , but the C22:1 content was significantly less than 1 inside the other 5 lines with either high or low oil contents. Following C22:1, C18:1 (oleic acid) was the main fatty acid component. Its contents were about 30 inside the two lines with high C22:1 content material and about 60 within the remaining. The other individuals fatty acids did not show any statistical differences. Our results indicated that the oil content was not correlated with fatty acid composition. Breeding varieties with higher oleic acid for the food business or high erucic acid for non-food applications in oilseed are two major objectives of B. napus breeding applications [17].Analysis of Correlations in between Oil Content with Other Seed TraitsThe correlation analyses of six mature seed traits, including oil content material, protein content, seed coat ratio, cotyledon ratio, radicle ratio and 1000-seed weight of 68 B. napus lines have been performed. The correlation coefficients of all six mature seed traits have been analyzed, and the benefits are offered in Table 2.Table 1.
