Enhanced production of nitrogenase components in Nicotiana benthamiana through co-expression with Bacterioferritin A

Alejandro M. Armas, Viviana Escudero, Julia Quintana, Mario Rodríguez‐Simón, Isidro Abreu, Juan Andrés Collantes-García, Bidya B. Gupta, Elisa de Ansorena, Daniel Raimunda, Luis Manuel Rubio, Manuel González‐Guerrero

This paper shows that co-expressing Bacterioferritin A with NifU in Nicotiana benthamiana increases NifU and NifH production, aiding nitrogenase cofactor assembly.
