VHb derived from Vitreoscilla has been widely used to improve the waterlogging tolerance in multiple plants. In this study, VHb gene was transformed into maize by bombardment. Under waterlogging treatment, transgenic VHb maize displayed higher shoot height, longer primary root length, more lateral root number, heavier shoot and root dry weight than their WT. With the present of exogenous VHb gene, maize exhibited enhanced tolerance to waterlogging stress.
