Effect of AtFAX1- and AtABCA9-OEs on seed weight, seed size, seed oil content, and oil yield. a Thousand-seed weight and seed morphology of camelina dry seeds. Values are means ± SE (n = 12). Bar = 3 mm. b Seed length and width of camelina dry seeds. Values are means ± SE (n = 30). c Seed yield per plant (g), Seed oil content (w/w), and oil yield per plant (g) of different camelina lines. AtFAX1- and AtABCA9-single and double OEs were grown side by side together with WT. Seeds from whole plant were harvested and dried at room temperature for at least one month before measurement. Seed oil content was measured by gas chromatography, and calculated based on the internal standard (C17:0) peak area. Seeds from each plant were measured with 3 technical replicates, and the mean values are represented here as the seed oil content of each plant. Black lines show the averages, white lines represent individual data points (n = 18), and polygons represent the estimated density of the data. Homozygous, T3-generation OE lines were used for this and subsequent characterization. Capital letters indicate a significant difference (P < 0.01) based on Duncan-test
