Photosynthate costs associated with the utilization of different nitrogen–forms: influence on the carbon balance of plants and shoot–root biomass partitioning
The photosynthate costs of processes (amino acid and protein synthesis and turnover, and pH regulation) associated with the utilization of nitrate (NO3−), ammonium (NH4+) or glutamine (Gln) for plant growth were estimated. Based on these estimates, the effects of these forms of nitrogen (N) on the c...

| description | The photosynthate costs of processes (amino acid and
protein synthesis and turnover, and pH regulation)
associated with the utilization of nitrate
(NO3−), ammonium
(NH4+) or glutamine (Gln) for plant
growth were estimated. Based on these estimates, the effects
of these forms of nitrogen (N) on the carbon balance of plants and
on shoot–root biomass allocation were evaluated. The
results indicated that NO3−
as an N source for plant growth
is not substantially more expensive to utilize than either
NH4+ or Gln, particularly in the long
term when costs due to protein turnover dominate the total
costs of N utilization. It is also suggested that the
photosynthate use in processes associated with N assimilation
has little impact on the carbon balance of plants, and hence on
shoot–root biomass allocation. |
