Elaeis than oils made from canola, corn, linseed, soybeans, safflower, and sunflowers, it can withstand extreme deep-frying heat and resists oxidation. It contains no trans fat, and its use in food has increased as food-labelling laws have changed to specify trans fat content. Oil from "Elaeis guineensis" is also used as biofuel. Human use of oil palms may date back to about 5,000 years in coastal west Africa. Palm oil was also discovered in the late 19th century by archaeologists in a tomb at Abydos dating back to 3000 BCE. It is thought that Arab traders brought the oil palm to
Phytomonas more economically significant crops, namely coconut ("Cocos nucifera") and oil palm ("Elaeis guineensis"). Finally, in 1982, Dollet successfully cultivated trypanosomatids "in vitro", which allowed for the isolation of "Phytomonas" in 24 different plant families from across the globe. While there has been recent genetic work done on "Phytomonas" species, genome level analysis is limited compared to the genome data available for disease causing trypanosomatids in animals and humans, especially "Trypanosoma cruzi", "Trypanosoma brucei", and "Leishmania major". In 2015, "Phytomonas nordicus" was found to be a part of the generally heteroxenous "Phytomonas" genus, despite it being a monoxenous parasite of the
