Abstract: Camelina sativa L. Crantz is a new and potential industrial oilseed crop with low input and environment-friendly. The seed yields 43%(W/W)oil with α-linolenic acid content over 35%. The seed oil can be used for edible oil and animal feed, health-promoting food, biofuel oil and high-valued oil chemicals. In this study we characterize the important agronomic traits and the excellent oil properties of camelina. Particularly, we describe the genetic improvements of the seed oil quality by gene engineering, which include pathway assembly of long chain polyunsaturated fatty acids, ω-7 fatty acids, wax esters, medium- and short-chain fatty acids, and enrichment of single fatty acid. We also dissect and discuss trends in camelina functional genomics and the prospects for development of camelina commercialization as a new bioenergy oilseed in China.

Key words: Camelina sativa L. Crantz, oil, fatty acid, biofuel oil, metabolic engineering
