Fig. 1: GWAS for the eight salt-tolerance traits.
From: Genome-wide association studies identify OsWRKY53 as a key regulator of salt tolerance in rice
A Salt response of representative rice varieties in the GWAS. – and + represented control and 140 mM NaCl treatment, respectively. B Frequency distribution of water content under salt treated. Arrows represented control accessions, and Nona Bokra was tolerant to salt stress and Koshihikari was a salt sensitive variety. C Frequency distribution of shoot Na+ content under salt treated. D Population structure. The colored subsections within each vertical bar indicated membership coefficient (Q) of the accession to different clusters. E Neighbor-joining clustering of landraces based on genetic distance. The scale bar showed substitutions per site. The colors of the bar and the tree branch indicated the five groups identified through the STRUCTURE program. F Principal components analysis for the 268 rice varieties based on whole-genome sequence data. PC1, PC2, and PC3 indicated eigenvectors of top principal components 1, 2 and 3, respectively. G Overview of MLM with OsWRKY53 highlighted in red. Scale: −log10 of P value of markers. Manhattan plots for WC. H Overview of MLM with OsMKK10.2 highlighted in red. Scale: −log10 of P value of markers. Manhattan plots for SFW. Mixed linear model was used to calculate P value.
