Hydro-Responsive Curling of the Resurrection Plant Selaginella lepidophylla
The spirally arranged stems of the spikemoss Selaginella lepidophylla, an ancient resurrection plant, compactly curl into a nest-ball shape upon dehydration. Due to its spiral phyllotaxy, older outer stems on the plant interlace and envelope the younger inner stems forming the plant centre. Stem curling is a morphological mechanism that limits photoinhibitory and thermal damages the plant might...
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 کاملDesiccation 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 کاملEngineered Plant Minichromosomes: A Resurrection of B Chromosomes?
A number of crop species of commercial interest have been transformed using either Agrobacterium-mediated, biolistic, or other systems. However, these methods have several limitations. For example, they allow insertion of single or a few genes at random genomic positions, but complex traits cannot be transferred in a coordinated manner. Furthermore, the integrity of the host genome can be distu...
