Ground-level ozone (O) is one of the major air pollutants， which cause oxidative injury to plants. The physiological and biochemical mechanisms underlying the responses of plants to O stress have been well investigated. However， there are limited reports about the molecular basis of plant responses to O. In this study， a comparative transcriptomic analysis of Pak Choi (Brassica campestris ssp. chinensis) exposed to different O concentrations was conducted for the first time.
