| Research Abstract |
This study has been focused on the functions of NADPH oxidase on pollen tube growth. I analyzed the functions of AtRbohH and AtRbohJ genes that encode NADPH oxidase in Arabidopsis. I showed that both proteins have ROS (reactive oxygen species)-producing activities as NADPH oxidase using a heterologous expression system. Also I showed that both genes specifically expressed in pollen. atrbohH and atrbohJ double mutant was defective in pollen tube tip growth. These results suggest that ROS produced by AtRbohH and AtRbohJ play a critical role in the pollen tube tip growth.
