Principal component analysis among the red and green T. urticae populations feeding on the four hosts. PCA plot of the transcript levels from the six red and green T. urticae populations on the original host and three transferred hosts (cotton, cucumber and eggplant). Average FPKM values of each population fed on each of four hosts were used as input for analysis. HG (Inner Mongolia population of the green T. urticae); NG (Jiangsu population of the green T. urticae); SG (Shandong population of the green T. urticae); BR (Beijing population of the red T. urticae); GR (Guizhou population of the red T. urticae); SR (Shandong population of the red T. urticae)
