Desiccation Tolerance Studied in the Resurrection Plant Craterostigma plantagineum.
This review will focus on the acquisition of desiccation tolerance in the resurrection plant Craterostigma plantagineum. Molecular aspects of desiccation tolerance in this plant will be compared with the response of non-tolerant plants to dehydration. Unique features of C. plantagineum are described like the CDT-1 (Craterostigma desiccation tolerance gene-1) gene and the carbohydrate metabolism...
متن کاملPhotosynthetic carbohydrate metabolism in the resurrection plant Craterostigma plantagineum.
The resurrection plant Craterostigma plantagineum (Hochst) is able to survive almost complete tissue dehydration when water is withheld from it, and then can rehydrate rapidly on rewatering. This ability is believed to be the result of the accumulation of sucrose in aerial tissues as a result of metabolism of 2-octulose. In this work the metabolic activity of well-watered Craterostigma plantagi...
متن کاملPolyamine metabolic canalization in response to drought stress in Arabidopsis and the resurrection plant Craterostigma plantagineum.
In this work, we have studied the transcriptional profiles of polyamine biosynthetic genes and analyzed polyamine metabolic fluxes during a gradual drought acclimation response in Arabidopsis thaliana and the resurrection plant Craterostigma plantagineum. The analysis of free putrescine, spermidine and spermine titers in Arabidopsis arginine decarboxylase (adc1-3, adc2-3), spermidine synthase (...
متن کاملDesiccation of the resurrection plant Craterostigma plantagineum induces dynamic changes in protein phosphorylation.
Reversible phosphorylation of proteins is an important mechanism by which organisms regulate their reactions to external stimuli. To investigate the involvement of phosphorylation during acquisition of desiccation tolerance, we have analysed dehydration-induced protein phosphorylation in the desiccation tolerant resurrection plant Craterostigma plantagineum. Several dehydration-induced proteins...
متن کاملThe role of transketolase and octulose in the resurrection plant Craterostigma plantagineum
Phylogenetic analysis revealed that Craterostigma plantagineum has two transketolase genes (transketolase 7 and 10) which are separated from the other transketolase genes including transketolase 3 from C. plantagineum We obtained recombinant transketolase 3, 7, and 10 of C. plantagineum and showed that transketolase 7 and 10 of C. plantagineum, but not transketolase 3, catalyse the formation of...
