Description:
Oil palm is the most productive oil-bearing crop. Although it is planted on only 5% of the total world vegetable oil acreage, palm oil accounts for 33% of vegetable oil and 45% of edible oil worldwide, but increased cultivation competes with dwindling rainforest reserves. We report the 1.8-gigabase (Gb) genome sequence of the African oil palm Elaeis guineensis, the predominant source of worldwide oil production. A total of 1.535 Gb of assembled sequence and transcriptome data from 30 tissue types were used to predict at least 34,802 genes, including oil biosynthesis genes and homologues of WRINKLED1 (WRI1), and other transcriptional regulators, which are highly expressed in the kernel. We also report the draft sequence of the South American oil palm Elaeis oleifera, which has the same number of chromosomes (2n = 32) and produces fertile interspecific hybrids with E. guineensis but seems to have diverged in the New World. Segmental duplications of chromosome arms define the palaeotetraploid origin of palm trees. The oil palm sequence enables the discovery of genes for important traits as well as somaclonal epigenetic alterations that restrict the use of clones in commercial plantings, and should therefore help to achieve sustainability for biofuels and edible oils, reducing the rainforest footprint of this tropical plantation crop.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3929164/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉 〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3929164/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Singh, Rajinder -- Ong-Abdullah, Meilina -- Low, Eng-Ti Leslie -- Manaf, Mohamad Arif Abdul -- Rosli, Rozana -- Nookiah, Rajanaidu -- Ooi, Leslie Cheng-Li -- Ooi, Siew-Eng -- Chan, Kuang-Lim -- Halim, Mohd Amin -- Azizi, Norazah -- Nagappan, Jayanthi -- Bacher, Blaire -- Lakey, Nathan -- Smith, Steven W -- He, Dong -- Hogan, Michael -- Budiman, Muhammad A -- Lee, Ernest K -- DeSalle, Rob -- Kudrna, David -- Goicoechea, Jose Luis -- Wing, Rod A -- Wilson, Richard K -- Fulton, Robert S -- Ordway, Jared M -- Martienssen, Robert A -- Sambanthamurthi, Ravigadevi -- Howard Hughes Medical Institute/ -- England -- Nature. 2013 Aug 15;500(7462):335-9. doi: 10.1038/nature12309.
