QRT-PCR analysis showed that AtPERK4 regulate root cell elongation related genes in plant to restrain the root cell growth; the upregulated H_2O_2-induced gene AtOXII suggests H_2O_2 may participate in the ABA signaling transduction pathway in restraining root growth.
总之，ABA抑制拟南芥根生长中，AtPERK4参与了ABA的信号转导，通过调控相应基因的转录抑制了根细胞的生长。
