Transcriptome Analysis of Potato Leaves Expressing the Trehalose-6-Phosphate Synthase 1 Gene of Yeast
Transgenic lines of the potato cultivar White Lady expressing the trehalose-6-phosphate synthase (TPS1) gene of yeast exhibit improved drought tolerance, but grow slower and have a lower carbon fixation rate and stomatal density than the wild-type. To understand the molecular basis of this phenomenon, we have compared the transcriptomes of wild-type and TPS1-transgenic plants using the POCI mic...
متن کاملTrehalose-6-phosphate synthase/phosphatase complex from bakers' yeast: purification of a proteolytically activated form.
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...
متن کاملA trehalose-6-phosphate synthase gene from Phellinus igniarius
Trehalose, an important disaccharide in fungal spores, plays important role in protects against many environmental stresses, such as heat and salt. In this study, a gene (PiTPS) encoded trehalose-6-phosphate synthase was isolated from Phellinus igniarius (L.: Fr.) Quél, a basidiomycete fungus belonging to the family Polyporaceae. It contains many bioactive compounds that have been reported to p...
متن کاملEXPRESSION OF HEAT SHOCK PROTEIN AND TREHALOSE-6-PHOSPHATE SYNTHASE HOMOLOGUES Expression of heat shock protein and trehalose-6-phosphate synthase homologues induced during water deficit in cotton
Tolerance to drought in plants is not a simple trait, but a complex of mechanisms working in combination to avoid or to resist water deficit. Genotypes that differ in tolerance to water deficit may show qualitative and quantitative differences in gene expression when submitted to drought periods. Four cotton (Gossypium hirsutum L.) genotypes (Siokra L-23, Stoneville 506, CS 50 and T1521) with c...
متن کاملTrehalose metabolism in Arabidopsis: occurrence of trehalose and molecular cloning and characterization of trehalose-6-phosphate synthase homologues.
Axenically grown Arabidopsis thaliana plants were analysed for the occurrence of trehalose. Using gas chromatography-mass spectrometry (GC-MS) analysis, trehalose was unambiguously identified in extracts from Arabidopsis inflorescences. In a variety of organisms, the synthesis of trehalose is catalysed by trehalose-6-phosphate synthase (TPS; EC 2.4.1.15) and trehalose-6-phosphate phosphatase (T...
