Figure 1: Phylogenetic relationships of FAD genes from G. hirsutum, Arabidopsis, and rice.

A Neighbor-Joining (NJ) phylogenetic tree of all detected FAD genes was constructed, using MEGA 5.2 program with bootstrap test (replicated 1000 times). The Omega, First, Sphingolipid, and Front-end subfamily were marked in pink, blue, green, and yellow, respectively.
