Time 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 کاملRNA-Seq Analysis of the Response of the Halophyte, Mesembryanthemum crystallinum (Ice Plant) to High Salinity
Understanding the molecular mechanisms that convey salt tolerance in plants is a crucial issue for increasing crop yield. The ice plant (Mesembryanthemum crystallinum) is a halophyte that is capable of growing under high salt conditions. For example, the roots of ice plant seedlings continue to grow in 140 mM NaCl, a salt concentration that completely inhibits Arabidopsis thaliana root growth. ...
متن کاملA novel methyl transferase induced by osmotic stress in the facultative halophyte Mesembryanthemum crystallinum.
Molecular mechanisms of osmotic stress tolerance were studied in Mesembryanthemum crystallinum (ice plant), a facultative halophyte capable of adjusting to and surviving in highly saline conditions. We screened a subtracted cDNA library enriched for salt stress-induced mRNAs to identify transcripts involved in this plant's adaptation to salinity. One mRNA, Imt1, was found to be up-regulated in ...
متن کاملSalt Stress Increases the Level of Translatable mRNA for Phosphoenolpyruvate Carboxylase in Mesembryanthemum crystallinum.
Mesembryanthemum crystallinum responds to salt stress by switching from C(3) photosynthesis to Crassulacean acid metabolism (CAM). During this transition the activity of phosphoenolpyruvate carboxylase (PEPCase) increases in soluble protein extracts from leaf tissue. We monitored CAM induction in plants irrigated with 0.5 molar NaCl for 5 days during the fourth, fifth, and sixth week after germ...
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...
