Overexpression of GmZF351 increases seed oil content in transgenic Arabidopsis plants. A, Total FA contents in seeds of GmZF351 transgenic plants. Error bars indicate sd (n = 4). B, FA composition in seeds of GmZF351 transgenic plants. Error bars indicate sd (n = 4). C, Fat Red 7B staining of GmZF351 transgenic plants. Bar = 2 mm. D, TAG contents in seeds of GmZF351 transgenic plants. Error bars indicate sd (n = 3). DW, Dry weight. Asterisks indicate significant differences compared with Col-0 (*, P < 0.05 and **, P < 0.01).
