Economy of Nigeria of 5%. By 2012, expenditures stood at $31.61 billion, while revenues was $54.48 billion. Nigeria ranks sixth worldwide and first in Africa in farm output. The sector accounts for about 18% of GDP and almost one-third of employment. Nigeria has 19 million head of cattle, the largest in Africa. Though Nigeria is no longer a major exporter, due to local consumer boom, it is still a major producer of many agricultural products, including: cocoa, groundnuts (peanuts), rubber, and palm oil. Cocoa production, mostly from obsolete varieties and overage trees has increased from around 180,000 tons annually to 350,000 tons. Major
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
