Complex I has a unique structure in plants and includes extra subunits. Here, we present a novel study to define its protein constituents. Mitochondria were isolated from Arabidopsis thaliana cell cultures, leaves, and roots. Subunits of complex I were resolved by 3D blue-native (BN)/SDS/SDS-PAGE and identified by mass spectrometry. Overall, 55 distinct proteins were found, seven of which occur...

AtALMT1 (Arabidopsis thaliana ALuminum activated Malate Transporter 1) encodes an Arabidopsis thaliana malate transporter that has a pleiotropic role in Arabidopsis stress tolerance. Malate released through AtALMT1 protects the root tip from Al rhizotoxicity, and recruits beneficial rhizobacteria that induce plant immunity. To examine whether the overexpression of AtALMT1 can improve these trai...

Hyperaccumulation of heavy metals is substantial in some hyperaccumulators; however, few studies have been conducted to reveal the effect light irradiation on variations representative amino acids and photosynthetic indices, which can represent antioxidant capacity plants during phytoremediation. The physiochemical responses Arabidopsis thaliana Cd stress were compared six treatments. results e...

Arabidopsis is universally acknowledged as the model for dicotyledonous crop plants. Furthermore, some of the information gleaned from this small plant can be used to aid work on monocotyledonous crops. Here we provide an overview of the current state of knowledge and resources for the study of this important model plant, with comments on future prospects in the field from Professor Pamela Gree...

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...
