abstract：:Although the mechanism of accumulation of C8-C16 saturated fatty acids in seed oils has been well-studied, the control of stearic (C18:0) acid deposition in high stearate seed fat is still unclear. We investigated the mechanism that regulates high level of stearate and oleate (C18:1) accumulation in mango (Mangifera i...
