Boron uptake and distribution by oilseed rape (Brassica napus L.) as affected by different nitrogen forms under low and high boron supply
Ammonium (NH4+) and nitrate (NO3-) conversely alter pH of the rooting medium, and thus differentially affect the equilibrium between boric acid and borate in soil solution. This can alter boron (B) uptake by plants, which is passive under high, but facilitated (boric acid) or active (borate) under l...

Ammonium (NH4+) and nitrate (NO3-) conversely alter pH of the rooting medium, and thus differentially affect the equilibrium between boric acid and borate in soil solution. This can alter boron (B) uptake by plants, which is passive under high, but facilitated (boric acid) or active (borate) under low B supply. Therefore, the effect of NH4+ and NO3- forms was investigated on the growth, 10B uptake rate and accumulation, and expression of B transporters in Brassica napus grown with low (1 μM) or high (100 μM) 10B for five days in the nutrient solution. At the low 10B level, NO3--fed plants had the same specific 10B uptake rate, 10B accumulation and xylem 10B concentration as NH4NO3-fed plants but these attributes were reduced at the high 10B level. BnaBOR1;2 and BnaNIP5;1 were upregulated in roots of NO3-fed plants at low 10B supply. NH4+-fed plants had substantially lower dry matters; due to nutrient solution acidification (2.0 units)-induced deficiency of nitrogen, potassium, magnesium, and iron in plant shoots. Reduced transpiration rates resulted in lower 10B uptake rate and accumulation in the roots and shoots of NH4+-fed plants. BnaNIP5;1 in roots, while both BnaBOR1;2 and BnaNIP5;1 in shoots were upregulated in NH4+-fed plants at low 10B level. Collectively, NH4+-induced acidity and consequent lowering of 10B uptake induced the upregulation of B transport mechanisms, even at marginal 10B concentrations, while NO3--induced alkalinization resulted in altered B distribution between roots and shoots due to restricted B transport, especially at higher 10B supply. |
