Proteomic analysis of Mesembryanthemum crystallinum leaf microsomal fractions finds an imbalance in V-ATPase stoichiometry during the salt-induced transition from C3 to CAM.
The halophyte Mesembryanthemum crystallinum adapts to salt stress by salt uptake and switching from C3 photosynthesis to CAM (crassulacean acid metabolism). An important role in this process is played by transport proteins in the tonoplast of the central vacuole. In the present study we examine dynamic changes in the protein composition during salt-stress adaptation in microsomes from M. crysta...
متن کاملStarch degradation in chloroplasts isolated from C3 or CAM (crassulacean acid metabolism)-induced Mesembryanthemum crystallinum L.
C3 or crassulacean acid metabolism (CAM)-induced Mesembryanthemum crystallinum plants perform nocturnal starch degradation which is linear with time. To analyse the composition of metabolites released by isolated leaf chloroplasts during starch degradation we developed a protocol for the purification of starch-containing plastids. Isolated chloroplasts from C3 or CAM-induced M. crystallinum pla...
متن کاملTime Course of mRNA Induction Elicited by Salt Stress in the Common Ice Plant (Mesembryanthemum crystallinum).
In the facultative halophyte Mesembryanthemum crystallinum (common ice plant), irrigation with solutions containing NaCl induces an alternate mode of carbon dioxide fixation, Crassulacean acid metabolism (CAM). The salt stress protocol which we have established facilitates the study of CAM induction and the correlation of changes in metabolism and gene expression. We have studied the time cours...
متن کاملExpression during Salt Stress and Nucleotide Sequence of cDNA for Ferredoxin-NADP Reductase from Mesembryanthemum crystallinum.
In the facultative halophyte Mesembryanthemum crystallinum (common ice plant) the enzyme ferredoxin-NADP(+)-reductase (FNR) is coded for by a small family of 2 to 3 genes. We have determined the expression characteristics as the plants adapt to high salt and the nucleotide sequence of a full-length cDNA coding for the precursor of this chloroplast-located enzyme. On a developmental scale amount...
متن کاملLarge-scale mRNA expression profiling in the common ice plant, Mesembryanthemum crystallinum, performing C3 photosynthesis and Crassulacean acid metabolism (CAM).
The common ice plant (Mesembryanthemum crystallinum L.) has emerged as a useful model for molecular genetic studies of Crassulacean acid metabolism (CAM) because CAM can be induced in this species by water deficit or salinity stress. Non-redundant sequence information from expressed sequence tag data was used to fabricate a custom oligonucleotide microarray to compare large-scale mRNA expressio...
