Research Abstract |
We determined the sequences of four LWS loci, SWS1, RH1 and 8 nuclear reference genes. The results showed that FST values among different populations were significantly larger than those of the reference genes. This indicates that the polymorphism of LWS genes could be maintained bydivergent selection. In addition, we found that differences in the sequences for LWS2 caused difference in gene expression levels of LWS2 genes.
