  abstract = {{O}il palm ({E}laeis guineensis) produces two oils of major economic importance, commonly referred to as palm oil and palm kernel oil, extracted from the mesocarp and the endosperm, respectively. {W}hile lauric acid predominates in endosperm oil, the major fatty acids ({FA}s) of mesocarp oil are palmitic and oleic acids. {T}he oil palm embryo also stores oil, which contains a significant proportion of linoleic acid. {I}n addition, the three tissues display high variation for oil content at maturity. {T}o gain insight into the mechanisms that govern such differences in oil content and {FA} composition, tissue transcriptome and lipid composition were compared during development. {T}he contribution of the cytosolic and plastidial glycolytic routes differed markedly between the mesocarp and seed tissues, but transcriptional patterns of genes involved in the conversion of sucrose to pyruvate were not related to variations for oil content. {A}ccumulation of lauric acid relied on the dramatic up-regulation of a specialized acyl-acyl carrier protein thioesterase paralog and the concerted recruitment of specific isoforms of triacylglycerol assembly enzymes. {T}hree paralogs of the {WRINKLED}1 ({WRI}1) transcription factor were identified, of which {E}g{WRI}1-1 and {E}g{WRI}1-2 were massively transcribed during oil deposition in the mesocarp and the endosperm, respectively. {N}one of the three {WRI}1 paralogs were detected in the embryo. {T}he transcription level of {FA} synthesis genes correlated with the amount of {WRI}1 transcripts and oil content. {C}hanges in triacylglycerol content and {FA} composition of {N}icotiana benthamiana leaves infiltrated with various combinations of {WRI}1 and {F}at{B} paralogs from oil palm validated functions inferred from transcriptome analysis.},
