Overexpression of Acyl-ACP Thioesterases, and , Induce Distinct Gene Expression Reprogramming in Developing Seeds of .

We examined the substrate preference of acyl-ACP thioesterases, and , and gene expression changes associated with the modification of lipid composition in the seed, using transgenic plants overexpressing or under the control of a seed-specific promoter. seeds contained a higher level of total saturated fatty acid (FA) content, with 4.3 times increase in 16:0 palmitic acid, whereas seeds showed approximately 3% accumulation of 10:0 and 12:0 medium-chain FAs, and a small increase in other saturated FAs, resulting in higher levels of total saturated FAs.
