Fig. 4From: Differential gene expression in aphids following virus acquisition from plants or from an artificial mediumLocomotor activity (number of spatial zones crossed) of viruliferous and non-viruliferous M. persicae fed on plants or on artificial medium. Box plots show median (line), 25–75% percentiles (box) and 10–90% percentiles (whisker). Letters indicate significant differences between aphid status with the GLM followed by multiple comparisons; p-value < 0.05Back to article page
