trehalose is the alpha, alpha-1,1-linked glucose disaccharide. its metabolism is found in a wide variety of organisms and is seen as evolutionary old. trehalose metabolites are however present at only very low concentrations and their role in plants are not understood. the physiological effects of 100 mm trehalose on growth and carbon allocation in seedlings are characterized in this paper. tre...

Identification of Arabidopsis thaliana Col.0 metabolites by use of NMR spectroscopy is described in this chapter. Among the different extraction solvent tested, MeOD was the best solvent to extract phenolic compounds from Arabidopsis. By column chromatography using Sephadex LH-20 and prep HPLC, several flavonoids were isolated from the methanol extract of Arabidopsis, and their structures were ...

Microbes modify plant root permeability The provides mineral nutrients and water to the plant. Diffusion barriers seal root, preventing loss of internal nutrients. Salas-González et al. found that microbes living on in roots model Arabidopsis thaliana influence diffusion barrier formation, which affects balance (see Perspective by Busch Chory). Plants with modified show altered bacterial commun...

The DUF1644 family is a highly conserved and functionally unknown protein it has been demonstrated that significantly improved the salt tolerance of rice (non-halophytes). However, little understood about function gene in halophytes. This study aimed to investigate whether similar non-halophytes as halophytic species. functions ZmDUF1644 transferred from Zoysia matrella into non-halophytic Arab...

Trehalose is the non-reducing alpha-alpha-1, 1-linked glucose disaccharide. The biosynthesisprecursor of trehalose, trehalose-6-phosphate (T6P), is essential for plant development, growth,carbon utilization and alters photosynthetic capacity but its mode of action is not understood. In thecurrent research, 6 days old seedlings of Arabidopsis thaliana (Columbia ecotype) were grown inliquid cultu...
