The levels of ammonia-assimilating enzymes of Ipomoea spp. (morning glory) grown in suspension culture on a chemically defined medium are affected by various nitrogen sources. An increase in nitrate or ammonium concentrations in the growth medium ele

Ipomoea cells grown in a medium containing ammonium and nitrate preferentially used ammonium during the initial stages of growth but in the later stages assimilated nitrate rapidly regardless of the presence or absence of ammonium. Cells grown on nit

The magnesium level required to support full growth in batch suspension cultures of an Ipomoea sp. (Morning Glory) cell line in 2% sucrose media was less than 0.3 mM. The uptake of magnesium increased with increasing magnesium in the medium, and with

The levels and the developmental patterns of the two acid phosphatases in Ipomoea sp. (morning glory) were influenced by the pH of the medium and whether the cultures were grown in fermentors or shake flasks. The two enzymes, which appeared in the cu

Two acid phosphatases isolated from culturedIpomoea (moring glory) cells were separated by column chromatography on DEAE-cellulose. The two acid phosphatases have different pH optima (pH 4.8–5.0 and 6.0) and do not require the presence of divalent
