FIGURE 7.
Genome-wide association study for drought-tolerance and identification of the candidate gene PP2C on chromosome D04. (A) Local Manhattan plot (top) and LD heat map (bottom). The red dot indicates the SNP related to the drought-tolerance trait. The arrow indicates the location of PP2C. (B) The expression level of the candidate gene PP2C calculated via RNA-Seq. (C) The relative expression level (REL) of the candidate gene PP2C calculated via qRT-PCR. (D) Differences of relative hypocotyl length (RHL) among two haplotypes. ∗ and ∗∗ mean the 5% and 1% levels of significance, respectively.
