    1.14.19.2 | malfunction |
transgenic maize that expresses high levels of ZmSAD1 in its mature seeds shows reduced stearic acid content (1.57%) and a lower saturated to unsaturated fatty acid ratio (20.40%) relative to those (1.64% and 20.61%, respectively) of the control. Conversely, downregulation of ZmSAD1 in maize results in increased levels of stearic acid (1.78%), long-chain saturated acids (0.85%) and the ratio of saturated to unsaturated fatty acids (21.54%) relative to those (1.64%, 0.74%, and 20.61%, respectively) of the control, whereas the oleic acid (32.01%) level is significantly decreased relative to that (32.68%) of the control |

| 1.14.19.2 | metabolism |
under normal growth conditions, the stearoyl-ACP molecule is generally rapidly desaturated by SAD to form oleoyl-ACP inside the chloroplasts resulting in low presence of stearic acid in glycerolipids. The further desaturation or elongation of oleoyl-ACP into polyunsaturated fatty acids (PUFAs) can occur in either the chloroplast using the prokaryotic pathway, or the acyl-ACP molecules are exported outside the chloroplast as acyl-CoA molecules and enter the eukaryotic pathway |
