SummaryThe uptake of nitrate and ammonium by callus ofPlatycerium coronarium from the culture medium was examined. Nitrate reductase activity of photoautotrophic callus cultures under CO2 enrichment was significantly lower compared to the cultures without CO2 enrichment, but higher than that of heterotrophic callus cultured on medium with 2% (wt/vol) sucrose. When sucrose concentration of the heterotrophic culture was lowered to 0.2%, nitrate reductase activity increased. The level of nitrate… Expand

TLDR
The data are in agreement with the view that long-term exposure to high levels of CO2 can cause a decrease in photosynthetic capacity. Expand

Ammonium Influence on the Growth and Nitrate Reductase Activity of Paul's Scarlet Rose Suspension Cultures.
TLDR
Suspension cultures of Paul's Scarlet rose were grown in two defined media and it was shown that NH(4) (+) caused a 2-fold stimulation in growth and governed the pattern of development. Expand
Regulation of nitrate and nitrite reductase expression in Nicotiana plumbaginifolia leaves by nitrogen and carbon metabolites.
TLDR
The characterization of transgenic plants expressing either a NR cDNA controlled by the 35S CaMV promoter or a transcriptional fusion between the tobacco nia1 (NR structural gene) promoter and the beta-glucuronidase reporter gene, led us to conclude that C metabolite control is taking place at the transcriptional level.

Photosynthetic characteristics of a photoautotrophic cell suspension culture of soybean.
TLDR
Active cell division, low photosynthetic capacity, elevated respiration, and a low ratio of RuBPcase(initial)/phosphoenolpyruvate carboxylase are traits that SB-P cells share with young leaf cells, indicatingSB-P cell physiology may be comparable to that of young expanding leaves rather than that of mature leaves.
