Fig. 2From: Comprehensive survey and evolutionary analysis of genome-wide miRNA genes from ten diploid Oryza speciesDistribution of Tajima’s D (a) and Fu and Li’s F values (b) for 80 miRNA loci in 10 Oryza species. Negative values for both the tests are shown by most of the loci signifying a recent selective sweep in Oryza. The values on the X-axis are not drawn to the scaleBack to article page
