Fig. 2From: Identification of genes regulated by histone acetylation during root development in Populus trichocarpa Inhibition of root growth by TSA. The growth of regenerated roots was inhibited when subjected to indicated concentrations of TSA for 2Â weeks (a). TSA inhibited HDAC activities in the regenerated roots (b). The length of regenerated roots (c) and root number (d) were decreased by TSA in a dose-dependent mannerBack to article page
