EXPRESSION 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 کاملCoexpression characteristics of trehalose-6-phosphate phosphatase subfamily genes reveal different functions in a network context.
Arabidopsis thaliana databases are available that highlight the behavior of the transcriptome under literally hundreds of experimental manipulations, making attempts possible that integrate this information into gene networks. We present and discuss the functioning of a gene network model generated using deposited microarray experiments. Based on a graphical Gaussian model, the network describe...
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...
متن کاملThe biosynthesis of trehalose phosphate.
UDPG was prepared as described by Pontis et al. (2). Part of this material was kindly furnished by Dr. H. G. Pontis. UDP was prepared by heating UDPG at 100” in 0.03 N sulfuric acid for 10 minutes, followed by neutralization with barium hydroxide and chromatography on Whatman No. 3 paper with ethanol-ammonium acetate at pH 3.8 as solvent (3). Another sample of UDP was obtained by ion exchange c...
متن کاملThe Class II Trehalose 6-phosphate Synthase Gene PvTPS9 Modulates Trehalose Metabolism in Phaseolus vulgaris Nodules
Legumes form symbioses with rhizobia, producing nitrogen-fixing nodules on the roots of the plant host. The network of plant signaling pathways affecting carbon metabolism may determine the final number of nodules. The trehalose biosynthetic pathway regulates carbon metabolism and plays a fundamental role in plant growth and development, as well as in plant-microbe interactions. The expression ...
