Fig. 1. Distribution of SNPs between Gayabyeo and Nipponbare and SNPs between Taebaegbyeo and Nipponbare per 100kb in the 12 rice chromosomes. The x-axis represents the physical distance along each chromosome in mega base-pair (Mbp) unit. The y-axis indicates the number of DNA polymorphisms. The blue line represents frequency of SNPs between Gayabyeo and Nipponbare, and the red line represents frequency of SNPs between Taebaegbyeo and Nipponbare.
Fig. 2. Distribution of SNPs between Gayabyeo and Taebaegbyeo per 100kb in the 12 rice chromosomes. The x-axis represents the physical distance along each chromosome in mega base-pair (Mbp) unit. The y-axis indicates the common logarithm of the number of SNPs.
Fig. 3. Annotations of DNA polymorphisms between Gayabyeo and Taebaegbyeo. Nipponbare IRGSP 1.0 reference annotation was used for annotation. The number in each class is shown. NC-exon indicates non-coding exon.
