  abstract = {{F}ruit provide essential nutrients and vitamins for the human diet. {N}ot only is the lipid-rich fleshy mesocarp tissue of the oil palm ({E}laeis guineensis) fruit the main source of edible oil for the world, but it is also the richest dietary source of provitamin {A}. {T}his study examines the transcriptional basis of these two outstanding metabolic characters in the oil palm mesocarp. {M}orphological, cellular, biochemical, and hormonal features defined key phases of mesocarp development. {A} 454 pyrosequencing-derived transcriptome was then assembled for the developmental phases preceding and during maturation and ripening, when high rates of lipid and carotenoid biosynthesis occur. {A} total of 2,629 contigs with differential representation revealed coordination of metabolic and regulatory components. {F}urther analysis focused on the fatty acid and triacylglycerol assembly pathways and during carotenogenesis. {N}otably, a contig similar to the {A}rabidopsis ({A}rabidopsis thaliana) seed oil transcription factor {WRINKLED}1 was identified with a transcript profile coordinated with those of several fatty acid biosynthetic genes and the high rates of lipid accumulation, suggesting some common regulatory features between seeds and fruits. {W}e also focused on transcriptional regulatory networks of the fruit, in particular those related to ethylene transcriptional and {GLOBOSA}/{PISTILLATA}-like proteins in the mesocarp and a central role for ethylene-coordinated transcriptional regulation of type {VII} ethylene response factors during ripening. {O}ur results suggest that divergence has occurred in the regulatory components in thismonocot fruit compared with those identified in the dicot tomato ({S}olanum lycopersicum) fleshy fruit model.},
