A recent model which describes root foraging behavior distinguishes
between growth that is search behavior vs growth which is the
consequence of nutrient uptake. In thinking about how I might test
this model, it occurred that a mutant plant that would uptake, but
not assimilate the nutrient in question could be used. I know that
there is an Arabidopsis mutant which does not produce nitrate
reductase. I assume that this plants uptakes, but does not assimilate
N. Is there a mutant that cannot assimilate phosphate? How could I go
about getting seeds of such mutants for experiments?
Any information you can offer will be appreciated.
