Expansive evolution of the trehalose-6-phosphate phosphatase gene family in Arabidopsis.
Trehalose is a nonreducing sugar used as a reserve carbohydrate and stress protectant in a variety of organisms. While higher plants typically do not accumulate high levels of trehalose, they encode large families of putative trehalose biosynthesis genes. Trehalose biosynthesis in plants involves a two-step reaction in which trehalose-6-phosphate (T6P) is synthesized from UDP-glucose and glucos...
متن کاملMolecular Evolution of Trehalose-6-Phosphate Synthase (TPS) Gene Family in Populus, Arabidopsis and Rice
Trehalose-6-phosphate synthase (TPS) plays important roles in trehalose metabolism and signaling. Plant TPS proteins contain both a TPS and a trehalose-6-phosphate phosphatase (TPP) domain, which are coded by a multi-gene family. The plant TPS gene family has been divided into class I and class II. A previous study showed that the Populus, Arabidopsis, and rice genomes have seven class I and 27...
متن کاملDisruption of TPS2, the gene encoding the 100-kDa subunit of the trehalose-6-phosphate synthase/phosphatase complex in Saccharomyces cerevisiae, causes accumulation of trehalose-6-phosphate and loss of trehalose-6-phosphate phosphatase activity.
Preparations of the trehalose-6-phosphate synthase/phosphatase complex from Saccharomyces cerevisiae contain three polypeptides with molecular masses 56, 100 and 130 kDa, respectively. Recently, we have cloned the gene for the 56-kDa subunit of this complex (TPS1) and found it to be identical with CIF1, a gene essential for growth on glucose and for the activity of trehalose-6-phosphate synthas...
متن کاملThe trehalose pathway in maize: conservation and gene regulation in response to the diurnal cycle and extended darkness
Energy resources in plants are managed in continuously changing environments, such as changes occurring during the day/night cycle. Shading is an environmental disruption that decreases photosynthesis, compromises energy status, and impacts on crop productivity. The trehalose pathway plays a central but not well-defined role in maintaining energy balance. Here, we characterized the maize trehal...
متن کاملComposition and functional analysis of the Saccharomyces cerevisiae trehalose synthase complex.
In the yeast Saccharomyces cerevisiae, trehalose-6-phosphate synthase (TPS) and trehalose-6-phosphate phosphatase (TPP), which convert glucose 6-phosphate plus UDP-glucose to trehalose, are part of the trehalose synthase complex. In addition to the TPS1 (previously also called GGS1, CIF1, BYP1, FDP1, GLC6, and TSS1) and TPS2 (also described as HOG2 and PFK3) gene products, this complex also con...
