In a recent study, we demonstrated that the ROS-detoxifying genes of G. diazotrophicus PAL5 were coexpressed with the nif genes in laboratory growth cultures controlling ROS levels during oxygen-sensitive nitrogen-fixation activity (Alquéres et al. 2010). This raised the question of whether, during ...
