Abstract:
... NH₄⁺ is not only the primary nitrogen for rice, a well-known NH₄⁺ specialist, but is also the chief limiting factor for its production. Limiting NH₄⁺ triggers a series of physiological and biochemical responses that help rice optimise its nitrogen acquisition. However, the dynamic nature and spatial distribution of the adjustments at the whole plant level during this response are still unknown. He ...
