Extended Data Fig. 8: Genome-wide association mapping for fitness in the wet and dry field environments.
From: The strength and pattern of natural selection on gene expression in rice
Taking the top approximately 0.5% of SNPs (1,000 SNPs) with the strongest association to total lifetime fitness in the wet (magenta) and dry (blue) field conditions after genome-wide association mapping, we observed no enrichment for transcripts (n = 809 and 142 transcripts in the wet and dry fields, respectively) that were expressed in the leaves and had significant linear selection differentials S (n = 408 plants, t-test, two-sided, unadjusted P < 0.05) among transcripts (n = 1,960 transcripts in the wet field and n = 1,671 transcripts in the dry field) from genes in 100-kb regions surrounding these SNPs, compared to transcripts from genes in other genomic regions (χ2, not significant (ns); two-sided P = 0.862 for the wet field and P = 0.85 for the dry field). Supplementary Table 27 provides genome-wide association mapping results for total lifetime fitness in wet and dry conditions, and for flowering success and fecundity under drought conditions.
