Molecular investigations of boron nutrition have been initiated by the discovery of a novel mutant of Arabidopsis thaliana with an altered requirement for borOn, which has been implicated in counteracting toxic effects of aluminum on root growth of dicotyledonous plants. Expand
Asparagine and boric Acid cause allantoate accumulation in soybean leaves by inhibiting manganese-dependent allantoate amidohydrolase.
Elevated levels of allantoate in leaves of ureide-transporting soybeans fertilized with ammonium nitrate result from inhibition ofAllantoate degradation by asparagine and that Mn(2+) is a critical factor in this inhibition. Expand
Proposed physiologic functions of boron in plants pertinent to animal and human metabolism.
Interaction between borate and divalent cations like manganese may alter metabolic pathways, which could explain why higher concentrations of boron can be toxic to plants. Expand
Why boron?
The diversity of roles played by B might indicate that either the micronutrient is involved in numerous processes or that its deficiency has a pleiotropic effect. Expand
Root Growth Inhibition in Boron-Deficient or Aluminum-Stressed Squash May Be a Result of Impaired Ascorbate Metabolism
Findings show that root growth inhibition resulting from either boron deficiency or aluminum toxicity may be a consequence of disrupted ascorbate metabolism, and this is the first report of a correlation between borons nutrition, ascorBate concentration in root apices, and growth. Expand
Changes in ureide synthesis, transport and assimilation following ammonium nitrate fertilization of nodulated soybeans.
Abstract The effect of ammonium nitrate fertilization on ureide synthesis, xylem transport and assimilation was examined in four week old nodulated soybean plants. In nodules the activity ofExpand
Protein phosphorylation in pea root plastids.
Metabolism of exogenous glucose 6-phosphate by the oxidative pentose phosphate pathway in intact plastids abolished the phosphorylation of the 58 kDa protein and dihydroxyacetone phosphate, phosphoenolpyruvate and 3-ph phosphoglycerate inhibited phosphorylated protein and had a time-dependent effect.
