Oil genes amplification model related to gene duplication events in soybean

  a. The curved lines within inner circle, colored by green, linked paralog pairs on soybean 20 chromosomes produced by SST, b. LCT and c. ECH. Oil subfamily genes with lightgreen (DSL&SFA), lightblue (SML in ES), lightsalmon (FAE&W&CM), green (LS), grey (MAL in M), yellow (ML), black (MAL in M7), blue (S&S8) and red (SFA in P9). Colored curved lines linked nodulation gene pairs with Ks < 0.15.
