The resilience of the aquatic Isoëtes cangae to terrestrial environment: Insights into molecular and ecophysiological adaptations
The Isoëtes genus comprises a basal lineage of vascular plants with a wide distribution, including aquatic and terrestrial species, which can be attributed to environmental changes throughout its evolutionary history. The underwater quillwort, Isöetes cangae, is endemic to Lake Amendoim in the northern Amazon rainforest region of Brazil. To aid conservation strategies, we investigated the molecular and physiological changes associated with water column reduction and tolerance to terrestrial environments. Remarkably, this aquatic species has demonstrated a tolerance for periods without a water column during ex situ cultivation. Short-term experimental conditions (24 h) revealed upregulation of stress-related genes, while biochemical, morphological, and physiological parameters remained unchanged. In contrast, long-term terrestrial conditions (3–6 months) induced changes in the physiology and morphology of I. cangae, including an increase in antioxidant capacity, photoprotective mechanisms, and the preservation of reproductive structures. The Crassulacean Acid Metabolism was present in both aquatic and terrestrial conditions. Mature and immature spores were able to produce plants even after 12 months of desiccation, with desiccated spores generating more progeny than submerged spores.
期刊介绍:
Aquatic Botany offers a platform for papers relevant to a broad international readership on fundamental and applied aspects of marine and freshwater macroscopic plants in a context of ecology or environmental biology. This includes molecular, biochemical and physiological aspects of macroscopic aquatic plants as well as the classification, structure, function, dynamics and ecological interactions in plant-dominated aquatic communities and ecosystems. It is an outlet for papers dealing with research on the consequences of disturbance and stressors (e.g. environmental fluctuations and climate change, pollution, grazing and pathogens), use and management of aquatic plants (plant production and decomposition, commercial harvest, plant control) and the conservation of aquatic plant communities (breeding, transplantation and restoration). Specialized publications on certain rare taxa or papers on aquatic macroscopic plants from under-represented regions in the world can also find their place, subject to editor evaluation. Studies on fungi or microalgae will remain outside the scope of Aquatic Botany.
