During dehydration, the length of roots of the aquatic resurrection plant Chamaegigas intrepidus is reduced by only 15%, whereas the diameter of fully differentiated roots is reduced by 30 to 35%. Lateral shrinking of roots is exclusively caused by collapsing cells in the rhizodermis and exodermis, which cover the cortex like a velamen radicum. Apart from the endodermis the root cortex is composed of a single layer of extremely large and thin-walled cells which show a high stability even when… Expand

The aquatic resurrection plant Chamaegigas intrepidus – adaptation to multiple abiotic stresses and habitat isolation
Chamaegigas intrepidus is a tiny poikilohydrous member of the Linderniaceae growing endemically in ephemeral rock pools on granite outcrops in Central Namibia. Habitat conditions are characterised byExpand
Investigation into the ability of roots of the poikilohydric plant Craterostigma plantagineum to survive dehydration stress.
TLDR
The ability of the root system of the poikilohydric plant Craterostigma plantagineum to survive dehydration was investigated, and the maintenance of high sucrose contents in rehydrating roots is discussed as a possible survival strategy against recurrent desiccation events. Expand
Ephemeral pools as stressful and isolated habitats for the endemic aquatic resurrection plant
Ephemeral pools are widespread in (semi-)arid regions, where they form unique, mostly isolated habitats in an otherwise dry landscape matrix. They are characterized by extremely variable conditions,Expand
HABITAT CONDITIONS, POPULATION GENETICS AND NICHE PARTITIONING OF THE NAMIBIAN RESURRECTION PLANT CHAMAEGIGAS INTREPIDUS DINTER
TLDR
The patchy spatial distribution of suitable habitats within a rather impermeable landscape matrix causes a highly structured genetic diversity in Ch. Expand

A SCANNING ELECTRON MICROSCOPICAL STUDY OF HYDRATED AND DESICCATED SUBMERGED LEAVES OF THE AQUATIC RESURRECTION PLANT CHAMAEGIGAS INTREPIDUS
TLDR
The shrinking process in the leaves of Chamaegigas is mainly due to contractible xylem elements which are shown to contract like an accordion, and maximum shrinkage is restricted to living leaves. Expand
Abscisic acid (ABA) relations in the aquatic resurrection plant Chamaegigas intrepidus under naturally fluctuating environmental conditions.
TLDR
Investigations in Namibia showed drastic diurnal fluctuations in the pH of the rock pools, which increased from slightly acidic or neutral conditions during the morning to alkaline conditions (up to pH 12) during late afternoon, which would be expected to affect the ABA relations in the plant.

Cell wall characteristics and structure of hydrated and dry leaves of the resurrection plant Craterostigma wilmsii, a microscopical study
Summary The cell wall architecture of leaf tissues of the resurrection plant Craterostigma wilmsii at various stages of dehydration and rehydration was studied using electron microscopy andExpand
Survival strategies under extreme and complex environmental conditions: The aquatic resurrection plant Chamaegigas intrepidus
TLDR
Anatomical, biochemical and physiological adaptations to this complex of extreme environmental conditions are discussed such as contractive xylem, accumulation of abscisic acid, dehydrins and carbohydrates during desiccation, and the role of amino acids, ammonium, urea and urease for nitrogen nutrition.
