Immunogold localization of trehalose-6-phosphate synthase in leaf segments of wild-type and transgenic tobacco plants expressing the AtTPS1 gene from Arabidopsis thaliana.

Numai utilizatorii înregistrați pot traduce articole

Following the establishment of a transgenic line of tobacco (B5H) expressing the trehalose-6-phosphate synthase (TPS) gene from Arabidopsis thaliana, a preliminary immunolocalization study was conducted using leaves of adequately watered B5H and wild-type plants. Immunocytochemical staining,

Trehalose-6-phosphate phosphatases from Arabidopsis thaliana: identification by functional complementation of the yeast tps2 mutant.

It is currently thought that most flowering plants lack the capacity to synthesize trehalose, a common disaccharide of bacteria, fungi and invertebrates that appears to play a major role in desiccation tolerance. Attempts have therefore been made to render plants more drought-resistant by the

Differential multisite phosphorylation of the trehalose-6-phosphate synthase gene family in Arabidopsis thaliana: a mass spectrometry-based process for multiparallel peptide library phosphorylation analysis.

Numai utilizatorii înregistrați pot traduce articole

Multisite protein phosphorylation plays a fundamental role in metabolic regulation. To detect and quantify in vitro kinase phosphorylation activities, we developed a highly selective LC-MS/MS-based method using high resolution multiple reaction monitoring on a triple quadrupole mass spectrometer.

Genetic and physiological analysis of the relationship between partial resistance to clubroot and tolerance to trehalose in Arabidopsis thaliana.

Numai utilizatorii înregistrați pot traduce articole

In Arabidopsis thaliana the induction of plant trehalase during clubroot disease was proposed to act as a defense mechanism in the susceptible accession Col-0, which could thereby cope with the accumulation of pathogen-synthesized trehalose. In the present study, we assessed trehalose activity and

Determination of trehalose-6-phosphate in Arabidopsis thaliana seedlings by hydrophilic-interaction liquid chromatography-mass spectrometry.

Numai utilizatorii înregistrați pot traduce articole

A hydrophilic-interaction chromatography (HILIC) method coupled to electrospray ionization mass spectrometry (ESI-MS) was developed for the determination of trehalose-6-phophate (Tre6P) in Arabidopsis thaliana seedlings. The method was optimized for MS detection and separation of Tre6P from its

Trehalose-6-phosphate signaling regulates thermoresponsive hypocotyl growth in Arabidopsis thaliana.

Numai utilizatorii înregistrați pot traduce articole

Growth plasticity is a key mechanism by which plants adapt to the ever-changing environmental conditions. Since growth is a high-energy-demanding and irreversible process, it is expected to be regulated by the integration of endogenous energy status as well as environmental conditions. Here, we show

Truncation of Arabidopsis thaliana and Selaginella lepidophylla trehalose-6-phosphate synthase unlocks high catalytic activity and supports high trehalose levels on expression in yeast.

Numai utilizatorii înregistrați pot traduce articole

Plants, such as Arabidopsis thaliana and Selaginella lepidophylla, contain genes homologous with the trehalose-6-phosphate synthase (TPS) genes of bacteria and fungi. Most plants do not accumulate trehalose with the desert resurrection plant S. lepidophylla, being a notable exception. Overexpression

Overexpression of the trehalose-6-phosphate phosphatase family gene AtTPPF improves the drought tolerance of Arabidopsis thaliana.

Numai utilizatorii înregistrați pot traduce articole

Trehalose-6-phosphate phosphatases (TPPs), which are encoded by members of the TPP gene family, can improve the drought tolerance of plants. However, the molecular mechanisms underlying the dynamic regulation of TPP genes during drought stress remain unclear. In this study, we explored

Regulation of flowering by trehalose-6-phosphate signaling in Arabidopsis thaliana.

Numai utilizatorii înregistrați pot traduce articole

The timing of the induction of flowering determines to a large extent the reproductive success of plants. Plants integrate diverse environmental and endogenous signals to ensure the timely transition from vegetative growth to flowering. Carbohydrates are thought to play a crucial role in the

Trehalose 6-phosphate is indispensable for carbohydrate utilization and growth in Arabidopsis thaliana.

Numai utilizatorii înregistrați pot traduce articole

Genes for trehalose metabolism are widespread in higher plants. Insight into the physiological role of the trehalose pathway outside of resurrection plant species is lacking. To address this lack of insight, we express Escherichia coli genes for trehalose metabolism in Arabidopsis thaliana, which

The Trehalose 6-Phosphate Pathway Impacts Vegetative Phase Change in Arabidopsis thaliana

Numai utilizatorii înregistrați pot traduce articole

The vegetative phase change marks the beginning of adult phase in the life cycle of plants and is associated with a gradual decline in the microRNA miR156, in response to sucrose status. Trehalose 6-phosphate (T6P) is a sugar molecule with signaling function reporting the current sucrose state. To

Overexpression of the wheat trehalose 6-phosphate synthase 11 gene enhances cold tolerance in Arabidopsis thaliana.

Numai utilizatorii înregistrați pot traduce articole

Low temperature is a key stress factor for the growth and development of wheat (Triticum aestivum L.), and glycometabolism plays an important role in plant cold tolerance. Our previous study identified trehalose 6-phosphate synthase 11 gene (TaTPS11), which had a significantly different expression

Trehalose phosphate synthase 5-dependent trehalose metabolism modulates basal defense responses in Arabidopsis thaliana.

Numai utilizatorii înregistrați pot traduce articole

Despite the recent discovery that trehalose synthesis is important for plant development and abiotic stress tolerance, the effects of trehalose on biotic stress responses remain relatively unknown. In this study, we demonstrate that TREHALOSE PHOSPHATE SYNTHASE 5 (TPS5)-dependent trehalose

Trehalose-6-phosphate synthase 1 is not the only active TPS in Arabidopsis thaliana.

Numai utilizatorii înregistrați pot traduce articole

Trehalose metabolism is essential for normal growth and development in higher plants. It is synthesized in a two-step pathway catalysed by TPS (trehalose-6-phosphate synthase) and trehalose phosphatase. Arabidopsis thaliana has 11 TPS or TPS-like proteins, which belong to two distinct clades: class

An unexpected plethora of trehalose biosynthesis genes in Arabidopsis thaliana.

Numai utilizatorii înregistrați pot traduce articole

Trehalose accumulation has been documented in many organisms, such as bacteria and fungi, where it serves a storage and stress-protection role. Although conspicuously absent in most plants, trehalose biosynthesis genes were discovered recently in higher plants. We have uncovered a family of 11 TPS
