Fig. 4From: SSR marker development and intraspecific genetic divergence exploration of Chrysanthemum indicum based on transcriptome analysisComparison of GO annotations of positively selected genes between diploid and tetraploid C. indicum germplasms. Ka/Ks > 1, genes that have experienced positive selection; 1 > Ka/Ks > 0.5, genes that are experiencing positive selectionBack to article page
