Fig. 4From: Molecular characterization and modulated expression of histone acetyltransferases during cold response of the tick Dermacentor silvarum (Acari: Ixodidae)Levels of H3K9 acetylation in Dermacentor silvarum under different cold treatment conditions. A cold treatment for 3 days; B cold treatment for 6 days; C cold treatment for 9 days. Analyses were performed with three replications per treatment. Compared to the 26 °C group, * indicates a statistical difference using unpaired t-test at P < 0.05 and ** at P < 0.01Back to article page
