Use of plant colonizing bacteria as chassis for transfer of N2-fixation to cereals

- A global aim is to transfer N2-fixation to cereals.
- One approach is to transfer N2-fixation to bacteria that associate with cereals.
- Synthetic biology enables controlled transfer of N2-fixation to anaerobic bacteria.
- A N2-fixation cluster has been transferred to the associative aerobe P. protegens.
- Traits required for controlled N2-fixation in aerobic bacteria are considered.
