Transcriptomic Profiling of Arabidopsis thaliana Mutant pad2.1 in Response to Combined Cold and Osmotic Stress
The contribution of glutathione (GSH) in stress tolerance, defense response and antioxidant signaling is an established fact. In this study transcriptome analysis of pad2.1, an Arabidopsis thaliana mutant, after combined osmotic and cold stress treatment has been performed to explore the intricate position of GSH in the stress and defense signaling network in planta. Microarray data revealed th...
متن کاملCharacterization of an Arabidopsis thaliana DNA hypomethylation mutant
We have recently isolated two Arabidopsis thaliana DNA hypomethylation mutations, identifying the DDM1 locus, that cause a 70% reduction in genomic 5-methylcytosine levels [1]. Here we describe further phenotypic and biochemical characterization of the ddm1 mutants. ddm1/ddm1 homozygotes exhibited altered leaf shape, increased cauline leaf number, and a delay in the onset of flowering when comp...
متن کاملAn Arabidopsis thaliana mutant defective in chloroplast dicarboxylate transport.
Reactions of the photorespiratory pathway of C(3) plants are found in three subcellular organelles. Transport processes are, therefore, particularly important for maintaining the uninterrupted flow of carbon through this pathway. We describe here the isolation and characterization of a photorespiratory mutant of Arabidopsis thaliana defective in chloroplast dicarboxylate transport. Genetic anal...
متن کاملOsmotic stress is accompanied by protein glycation in Arabidopsis thaliana
Among the environmental alterations accompanying oncoming climate changes, drought is the most important factor influencing crop plant productivity. In plants, water deficit ultimately results in the development of oxidative stress and accumulation of osmolytes (e.g. amino acids and carbohydrates) in all tissues. Up-regulation of sugar biosynthesis in parallel to the increasing overproduction o...
متن کاملA cadmium-sensitive, glutathione-deficient mutant of Arabidopsis thaliana.
The roots of the cadmium-sensitive mutant of Arabidopsis thaliana, cad1-1, become brown in the presence of cadmium. A new cadmium-sensitive mutant affected at a second locus, cad2, has been identified using this phenotype. Genetic analysis has grown that the sensitive phenotype is recessive to the wild type and segregates as a single Mendelian locus. Assays of cadmium accumulation by intact pla...
