Exposure to 1 millimolar ammonium pretreatments increased V(max) for phosphorous uptake in dark-grown decapitated maize seedlings without a statistically measurable change in K(m). Sulfate uptake also was stimulated. The stimulation in phosphorous uptake due to ammonium pretreatment was greater in seedlings grown without phosphorous than in those grown with 25 micromolar phosphorous. The stimulus was not expressed unless the entire root system was pretreated with ammonium, and pretreatment of a… CONTINUE READING
