The phenomenon of multi-copy genes is common in plants. Pseudogene is defined as an inactive gene, which can not synthesize functional proteins but share the similar DNA sequences with normal functional genes. In this study, 56 FAD2 DNA clones and 47 FAD2 seed cDNA clones of Brassica napus cv. Xiangyou 15 were investigated, and six new copies of FAD2 were detected, designated as FAD2P1-6 respectively. This sequence length of six copies ranged from 1 141–1 157 bp and there were no introns in their open reading frames （ORF）. These six copies s...
