Identification of the causal gene for the locus pmG2.1. (a) Local Manhattan plot [9] and LD heatmap (bottom) surrounding the peak of pmG2.1. (b,e,h) SNP variation of the candidate gene Csa2G030010, Csa2G030020, and Csa2G030030 between the highly susceptible (HS) and highly resistant (HR) lines (see Supplementary File S5). (c,f,i) Disease index (DI) comparison between haplotypes of the HS and HR lines for the candidate gene Csa2G030010, Csa2G030020, and Csa2G030030, respectively. (d,g,j) RPKM (Reads Per Kilobase Million) of candidate gene Csa2G030010, Csa2G030020 and Csa2G030030, respectively, based on the transcriptome of PRJNA321023 (data obtained from http://cucurbitgenomics.org/rnaseq/home, accessed on 14 April 2021). ** indicates significance at p < 0.01.
