The study said substantial government intervention would be one way to create a market for camelina, by combining 9 percent government subsidy on camelina crop production, with 9 percent tax on the conventional fuel.


Etymology

The name ''Camelina'' comes from the Greek for "ground" and "flax", alluding to its being a weed which suppresses the vigour of flax crops.

Genetics

The first full genome sequence for ''Camelina sativa'' was released on August 1, 2013, by a Canadian research team. The genome sequence and its annotation are available in a genome viewer format and enabled for sequence searching and alignment. Technical details of Camelina's genome sequence were published on April 23, 2014 in the academic journal ''

''. Rothamsted Institute in the UK developed genetically modified ''Camelina sativa'' plants that accumulate in their seeds high levels of the longer chain omega-3 oils EPA and DHA, commonly found in fish oils. These plants could provide terrestrial sustainable sources of longer chain omega-3 fatty acids and have benefits for human health and the environment. Field trials were underway in 2016.


Species

Four common species are presented below. However, at least two databanks indicate more species may exist. * '' Camelina alyssum'' * '' Camelina microcarpa'' * ' * '' Camelina sativa''


Biodiesel

Biodiesel made from camelina has a variety of benefits. First, traditional petroleum or diesel fuel is not renewable resources, the production of these resources is finite. Camelina biodiesel, however, is a renewable resource. Camelina based aviation fuel could save 84% of carbon emissions. Camelina biodiesel can be produced in large quantities as feedstocks are enough. Moreover, camelina biodiesel can reduce the country's dependence on fossil resources, which can ensure the country's energy security. In addition, camelina biodiesel is an environmentally friendly fuel, and it is biodegradable. Besides, the development of the camelina biodiesel industry can bring employment opportunities. The government has given the industry strong support since camelina biodiesel has a variety of benefits. Therefore, camelina biodiesel has policy support. What's more, the development of the camelina biodiesel industry has brought great economic benefits. According to the investigation, the

of camelina biodiesel produced by no-till farming is lower than that of traditional methods.
