How plants relate their requirements for energy with the reducing power necessary to fuel growth is not understood. The activated glucose forms and NADPH are key precursors in pathways yielding, respectively, energy and reducing power for anabolic metabolism. Moreover, they are substrates or allosteric regulators of trehalose-phosphate synthase (TPS1) in fungi and probably also in plants. TPS1 ...
The role of trehalose in plants is a curious one. Originally believed to serve as an osmoprotectant, its presence in plants at very low levels makes this role unlikely. This month’s High Impact article by Avonce et al., titled ‘‘The Arabidopsis Trehalose-6-P Synthase AtTPS1 Gene Is a Regulator of Glucose, Abscisic Acid, and Stress Signaling,’’ appeared in our November 2004 issue and adds to the...
Considerable interest has been evoked by the analysis of the regulatory pathway in carbohydrate metabolism and cell growth involving the non-reducing disaccharide trehalose (TRE). TRE is at small concentrations in mesophytes such as Arabidopsis thaliana and Triticum aestivum, excluding a role in osmoregulation once suggested for it. Studies of TRE metabolism, and genetic modification of it, hav...
The dissacharide trehalose is an important intracellular osmoprotectant and the OtsA/B pathway is the principal pathway for trehalose biosynthesis in a wide range of bacterial species. Scaffolding proteins and other cytoskeletal elements play an essential role in morphogenetic processes in bacteria. Here we describe how OtsA, in addition to its role in trehalose biosynthesis, functions as an os...
Acquisition of thermotolerance in response to a preconditioning heat treatment at 40 degrees C was studied in mutants of the yeast Saccharomyces cerevisiae lacking a specific heat shock protein or the ability to synthesize proteins at 40 degrees C. A mutant carrying a deletion of heat shock protein hsp 104 and the corresponding wildtype strain were both highly sensitive to heat stress at 50.4 d...
Abstract Introduction Heart failure is a frequent death cause for oncological patients who received treatment with doxorubicin (DOX). DOX administration inhibits autophagy in cardiomyocytes and causes myocardial damage. Natural activators of (NAA) such as trehalose, natural disaccharide, spermidine, putrescine-derived polyamine initially isolated from semen, were previously found to be promisin...
