Expression analysis of 27 PtRab paralogous pairs. a Correlation of expression of 27 PtRab paralogous pairs across various tissues. x- and y-axis indicate FPKM values across 24 samples of two genes in each paralogous pair. For example, x-axis represents PtRabA1b and y-axis represents PtRabA1e in pair PtRabA1b/A1e. Expression values were shown in Table S3. b Expression validation of ten PtRab paralogous pairs response to various abiotic stresses using qRT-PCR. Red and green colors indicate up- and down-regulation of log2 transformed fold changes compared to control plants. c Correlation between duplication date and expression R2 of 27 PtRab paralogous pairs. Red dot circle includes seven pairs with highly similar patterns with R2 > 0.6
