Trehalose-6-phosphate synthase (TPS), as the key enzyme for the synthesis of plants trehalose, has effects of enhancing its anti-dehydration, as well as protecting biofilm, proteins, and others from harm. Additionally, reproductive isolation between species can be broken with transgenic technology, and beneficial gene of other species can be transformed and utilized to improve resistance of cro...

peppermint has considerable commercial value and widely cultivated for essential oil production, especially menthol. the aim of this study was to determine the quantitative expression of pulegone reductase (pr), menthofuran synthase (mfs) and limonene synthase (ls) genes in menthol biosynthesis pathway in mentha x piperita , using semiquantitative rt-pcr analysis and evaluating menthol producti...

Arabidopsis thaliana maintains a complex metabolism for the production of secondary or specialized metabolites. Such metabolites include volatile and semivolatile terpenes, which have been associated with direct and indirect defensive activities in flowers and leaves. In comparison, the structural diversity and function of terpenes in Arabidopsis roots has remained largely unexplored despite a ...

The TPS1 gene, encoding trehalose-6-phosphate synthase (TPS), exerts an essential control on the influx of glucose into glycolysis in the yeast Saccharomyces cerevisiae. The deletion of TPS1 causes an inability to grow on glucose because of a hyperaccumulation of sugar phosphates and depletion of ATP and phosphate. We show that expression of the Escherichia coli homologue, otsA, in a yeast tps1...

A protein of about 800 kDa with trehalose-6-phosphate synthase (TPS) and trehalose-6-phosphate phosphatase (TPP) activity was purified from bakers' yeast. This TPS/P complex contained 57, 86 and 93 kDa polypeptides. The 86 and 93 kDa polypeptides both appeared to be derived from a polypeptide of at least 115 kDa in the native enzyme. A TPS-activator (a dimer of 58 kDa subunits) was also purifie...

Compounds of the terpenoid class play numerous roles in the interactions of plants with their environment, such as attracting pollinators and defending the plant against pests. We show here that the genome of cultivated tomato (Solanum lycopersicum) contains 44 terpene synthase (TPS) genes, including 29 that are functional or potentially functional. Of these 29 TPS genes, 26 were expressed in a...

Trehalose, as a non-reductive disaccharide, plays vital role in plant growth and development resistance to abiotic stress. Trehalose-6-phosphate synthase (TPS) is key enzyme the synthesis mechanism of trehalose TPS1 genes play crucial response stress plants. However, it has rarely been reported that CaTPS1 responds cold salt stresses pepper. To verify function stresses, was silenced by virus-in...

A segment of DNA located between 131 and 311 base pairs (bp) upstream from the transcriptional start of the Myxococcus xanthus ops gene (-131 to -311) was shown to function as an upstream activation site (UAS) for developmentally regulated transcription from the tps gene promoter region. The activation of early developmental transcription by the ops UAS was independent of orientation and could ...
