  abstract = {{G}lobal demand for vegetable oils is increasing at a dramatic rate, while our understanding of the regulation of oil biosynthesis in plants remains limited. {T}o gain insights into the mechanisms that govern oil synthesis and fatty acid ({FA}) composition in the oil palm fruit, we used a multilevel approach combining gene coex- pression analysis, quantification of allele-specific expression and joint multivariate analysis of transcriptomic and lipid data, in an interspecific backcross population between the {A}frican oil palm, {E}laeis guineensis, and the {A}merican oil palm, {E}laeis oleifera, which display contrasting oil contents and {FA} compositions. {T}he gene coexpression network produced revealed tight transcriptional coordination of fatty acid synthesis ({FAS}) in the plastid with sugar sensing, plastidial glycolysis, transient starch storage and carbon recapture pathways. {I}t also revealed a concerted regulation, along with {FAS}, of both the transfer of nascent {FA} to the endoplasmic reticulum, where triacylglycerol assembly occurs, and of the production of glycerol-3-phosphate, which provides the backbone of triacylglycerols. {P}lastid biogenesis and auxin transport were the two other biological processes most tightly connected to {FAS} in the network. {I}n addition to {WRINKLED}1, a transcription factor ({TF}) known to activate {FAS} genes, two novel {TF}s, termed {NF}-{YB}-1 and {ZFP}-1, were found at the core of the {FAS} module. {T}he saturated {FA} content of palm oil appeared to vary above all in relation to the level of transcripts of the gene coding forb-ketoacyl-acyl carrier protein synthase {II}. {O}ur findings should facilitate the development of breeding and engineering strategies in this and other oil crops.},
