Cloning and characterization of the Cerasus humilis sucrose phosphate synthase gene (ChSPS1)

Sucrose is crucial to the growth and development of plants, and sucrose phosphate synthase (SPS) plays a key role in sucrose synthesis. To understand the genetic and molecular mechanisms of sucrose synthesis in Cerasus humilis, ChSPS1, a homologue of SPS, was cloned using RT-PCR. Sequence analysis showed that the open reading frame (ORF) sequence of ChSPS1 is 3174 bp in length, encoding a predi...

Sucrose phosphate synthase and sucrose accumulation at low temperature.

The influence of growth temperature on the free sugar and sucrose phosphate synthase content and activity of spinach (Spinacia oleracea) leaf tissue was studied. When plants were grown at 25 degrees C for 3 weeks and then transferred to a constant 5 degrees C, sucrose, glucose, and fructose accumulated to high levels during a 14-d period. Predawn sugar levels increased from 14- to 20-fold over ...

Cloning and characterization of the gene for phosphatidylcholine synthase.

Phosphatidylcholine (PC) is the major membrane-forming phospholipid in eukaryotes and can be synthesized by either of two pathways, the CDP-choline pathway or the methylation pathway. In prokaryotes only the methylation pathway was thought to occur. Recently, however, we could demonstrate (de Rudder, K. E. E., Sohlenkamp, C., and Geiger, O. (1999) J. Biol. Chem. 274, 20011-20016) that a second ...

Circadian Regulation of Sucrose Phosphate Synthase Activity

Sucrose phosphate synthase (SPS), a key enzyme in sucrose biosynthesis, is regulated by protein phosphorylation and shows a circadian pattern of activity in tomato. SPS is most active in its dephosphorylated state, which normally coincides with daytime. Applying okadaic acid, a potent protein phosphatase inhibitor, prevents SPS activation. More interesting is that a brief treatment with cyclohe...

Cloning of a sucrose-phosphate synthase gene highly expressed in flowers from the tropical epiphytic orchid Oncidium Goldiana.

Sucrose-phosphate synthase (SPS) is one of the key regulatory enzymes in carbon assimilation and partitioning in plants. It plays a crucial role in the production of sucrose in photosynthetic cells. The cloning and expression analysis of a full-length cDNA encoding SPS from tropical epiphytic orchid hybrid Oncidium Goldiana are reported here. The cDNA designated as sps1 is 3820 bp in length wit...
