Fig. 4

Range of homoeolog expression bias in different metabolic pathways. Box plot of log₂ showing the expression ratio of homoeologous gene pairs in each metabolic pathway. Red dotted line indicates the equal ratio log₂. Black dotted line indicates the threshold of expression ratio where the homoeologous gene pair is defined as biased (log₂FC (fold change) > 1). Orange and blue colours of the boxes indicate the direction of homoeolog expression bias, towards Fso_h and Fso_l, respectively
