An international team of scientists including researchers from the University of Georgia recently published the genome of Brassica napus-commonly known as canola-in the journal Science. Their discovery paves the way for improved versions of the plant, which is used widely in farming and industry.
Canola is grown across much of Canada and its native Europe, but the winter crop is increasingly cultivated in Georgia. Canola oil used for cooking is prized for its naturally low levels of saturated fat and rich supply of omega-3 fatty acids, but the plant is also used to produce feed for farm animals and as an efficient source for biodiesel.
UGA Regents Professor Andrew Paterson heads the university's Plant Genome Mapping Laboratory.
"This genome sequence opens new doors to accelerating the improvement of canola," said Andrew Paterson, Regents Professor, director of UGA's Plant Genome Mapping Laboratory and co-corresponding author for the study. "We can use this knowledge to tailor the plant's flowering time, make it more resistant to disease and improve a myriad of other traits that will make it more profitable for production in Georgia and across the country."
Canola has one of the most complex genomes among flowering plants, forming thousands of years ago during the Neolithic Era when two plant species-Brassica rapa and Brassica oleracea-combined in the wild. Plants in the B. rapa family include turnips and cabbages, while B. oleracea encompasses cauliflower, cabbage, collards, broccoli, kale and other common vegetables.
The Plant Genome Mapping Laboratory played prominent roles in the sequencing both B. rapa and B. oleracea in 2011 and 2014, respectively.
"Understanding the genomes of B. rapa and B. oleracea was key to piecing together the canola genome," Paterson said. "It's like a genetic love triangle between the three species, with canola sometimes favoring genes from B. rapa or B. oleracea or sometimes both."
While much the world's canola is used to make cooking oil and protein-rich animal feed, it is also used in the production of lipstick, lip gloss, soap, lotion, printing ink and de-icing agents.
The growing interest in carbon reduction and more environmentally friendly fuel alternatives is also good news for canola growers, as this genome sequence may ultimately help researchers develop feedstocks that are suited to more sustainable biofuel production.
Global canola production has grown rapidly over the past 40 years, rising from the sixth largest oil crop to the second largest, according to the U.S. Department of Agriculture.
Much of the production in America is concentrated along the northern plains, but the recent construction of a canola processing plant near the South Carolina-Georgia border has spurred interest for growers in the Southeast.
Additional UGA researchers for the project include Xiyin Wang, assistant research scientist and co-first author for the paper; Tae-ho Lee and Yupeng Wang, former postdoctoral researchers; and current and former graduate students Hui Guo, Huizhe Jin, Jingping Li, Xu Tan, Haibao Tang, and Yupeng Wang.

Wind turbines could be installed under some of the biggest bridges on the road network to produce electricity. So it is confirmed by calculations carried out by a European researchers team, that have taken a viaduct in the Canary Islands as a reference. This concept could be applied in heavily built-up territories or natural areas with new constructions limitations.
The Juncal Viaduct, in Gran Canaria, has served as a reference for Spanish and British researchers to verify that the wind blowing between the pillars on this...
