Flax (Linum usitatissimum L.) is an important crop with many characteristic features such as its abundant essential ω-3 fatty acids for human nutrition. Fatty acid (FA) biosynthesis in plants, including flax, involves several consecutive steps governed by different gene families. Using in silico gene mining and comparative analysis, genome-wide gene identification and characterization were performed for six gene families related to FA biosynthesis, including KAS, SAD, FAD, KCS and FAT. We identified 91 FA-related genes from flax cv. CDC Bethune genome, from which seven previously cloned genes were validated. The newly identified 84 FA-related genes include 14 novel genes from the KAS family, two from the SAD family, 13 from the FAD2 family, three from the FAD3 family, 38 from the KCS family and 14 from the FAT family. Out of the 91 genes identified, 88 were duplicated as a conse.. View More»
