25 Jul 2013: Mapping of Oil Palm Genome
Could Boost Productivity of Key Crop

Scientists say they have identified the gene responsible for the yield of oil palm crops, a discovery that could boost the productivity of the world’s top source of vegetable oil and help reduce the size of oil

palm plantations in the world’s tropical regions. Writing in the journal Nature, Malaysian and U.S. researchers describe the mapping of the genome of the oil palm, whose products are used in everything from food to cosmetics to biofuels. According to the scientists, the so-called “shell gene” controls “how the thickness of its shell correlates to fruit size and oil yield.” The fruit of the African palm oil tree comes in three varieties: a thick-shelled dura, a shell-less pisifera, and a thin-shelled tenera, which produces a greater oil yield. According to scientists, the shell gene plays a key role in a mutation that produces the more commercially productive tenera variety. “This gene mutation explains the single most important economic trait in oil palm and has implications for the competing interests of global edible oil production, biofuels and rain forest conservation,” the scientists said. In recent decades, palm oil development has been one of the leading causes of forest loss in some of the world’s most important tropical rainforests, particularly in Malaysia and Indonesia.
