Fig. 2From: Reference genes for accurate gene expression analyses across different tissues, developmental stages and genotypes in rice for drought toleranceWRS of the reference gene candidates. Radar chart displays the WRS of each reference gene candidate in the five datasets (A to E in each graph). Vertices of the chart represent percentage scores of WRS calculated for genes in each gene family. The highest WRS was adjusted to 100 %. a GAPDH, b actin, c ubiquitin and d cyclophilin Back to article page
