ANSWER
...............
******************Nitrogen is an essential nutrient in plant growth.
The ability of a plant to supply all or part of its requirements from biological nitrogen fixation (BNF) thanks to interactions with endosymbiotic, associative and endophytic symbionts,
****** confers a great competitive advantage over non-nitrogen-fixing plants.
********************. NOW *********†**********
BNF in legumes is well documented, this review focuses on BNF in non-legume plants.
Despite the phylogenic and ecological diversity among diazotrophic bacteria and their hosts, tightly regulated communication is always necessary between the microorganisms and the host plant to achieve a successful interaction.
Ongoing research efforts to improve knowledge of the molecular mechanisms underlying these original relationships and some common strategies leading to a successful relationship between the nitrogen-fixing microorganisms and their hosts are presented.
