Transgenic Nicotiana tabacum L. (tobacco) plants expressing an unregulated gene for pyrophosphate-dependent fructose-6-phosphate 1-phosphotransferase (PFP) from the fermentor protist Giardia lamblia were produced. Independently transformed lines revealed a high level of Giardia PFP activity but unaltered activities of native plant PFP, phosphofructokinase, and fructose-1,6-bisphosphatase. Transgenic plants exhibited a decrease in total biomass but no dramatic physiological or morphological alterations or significant reduction of seed yield. Both source and sink tissues demonstrated altered partitioning: leaf starch was significantly lower at the beginning and end of the daily light period and young seeds had lower starch but higher lipid levels, and these changes were correlated with PFP activity. Transgenic seeds had significantly higher percentages of germination, and microscopic examination of these seeds showed a temporal enhancement in growth of the young embryo. The significance of these results as they relate to our current understanding of PFP is discussed.Key words: pyrophosphate-dependent fructose-6-phosphate 1-phosphotransferase (PFP), transgenic, Nicotiana tabacum, glycolysis, photosynthate partitioning.

The use of carbon dioxide, acetate, and leucine in the synthesis of lamellar lipoprotein was investigated in chloroplasts of Nicotiana tabacum L. seedlings. These 14C-labelled substrates were fed to sterile seedlings and lamellae were isolated from seedling chloroplasts. The major lamellar lipoprotein was extracted by continuous-flow polyacrylamide gel electrophoresis and the lipoprotein was separated into protein and lipid fractions.All of the substrates were incorporated into both protein and lipid. Carbon dioxide and acetate incorporation was more strongly light dependent than leucine. Light–dark and protein–lipid incorporation ratios were established for each substrate. Leucine label was found in many lamellar amino acids.
