Deposition of stearate-oleate rich seed fat in Mangifera indica is mediated by a FatA type acyl-ACP thioesterase

► Mechanism that regulates high level of stearate and oleate accumulation in mango. ► Induction of specialized fatty acyl-ACP thioesterase (Fat). ► Purification of a heat-labile thioesterase. ► Its confirmation as FatA by mass spectrometric analysis. ► Partial purification of a heat-stable FatB type thioesterase.
