Symbiotic nitrogen fixation represents a crucial yet energy-demanding strategy for legumes to survive in nutrient-poor soils. We highlight the multifaceted roles of NSP1 and NSP2 in this symbiosis and propose their function as 'nutrient-responsive regulators', integrating environmental signals, physiological status, and nutrient availability, to ensure nodulation occurs only under favorable conditions.
