Zostera marina and Ruppia maritima often share the same habitat, but R. maritima appears more resistant to environmental stress. We investigated the impact of light intensity and water column O2 concentrations on radial oxygen loss (ROL), in young specimens of Z. marina and R. maritima. Planar optode imaging revealed that ROL of Z. marina was localized to the root tip, while R. maritima showed ROL along extensive root sections. The total root biomass of the 2 spe- cies was similar, but, while R…

Dynamics of oxygen and carbon dioxide in rhizospheres of Lobelia dortmanna - a planar optode study of belowground gas exchange between plants and sediment.

A tight coupling between photosynthetic processes and the spatiotemporal dynamics of O2 and CO2 in the rhizosphere of Lobelia was demonstrated, and it is suggested that O2 -induced stimulation of the microbial community in the sediment increases the supply of inorganic carbon for photosynthesis by building up a CO2 reservoir in therhizosphere.

Spatial heterogeneity and short-term oxygen dynamics in the rhizosphere ofVallisneria spiralis: Implications for nutrient cycling

Aquatic macrophytes modify the sediment biogeochemistry via radial oxygen loss (ROL) from their roots. However, the variation in ROL and its implication for nutrient availability remains poorly

Rhizome, Root/Sediment Interactions, Aerenchyma and Internal Pressure Changes in Seagrasses

Life in seawater presents several challenges for seagrasses owing to low O2 and CO2 solubility and slow gas diffusion rates. Seagrasses have evolved numerous adaptations to these environmental

High Resolution Assessment of Spatio-Temporal Changes in O2 Concentration in Root-Pathogen Interaction

Assessment of how tomato roots influence the metabolic activity and growth patterns of Fol shows that the fungal metabolism, measured as oxygen consumption, increases within a few hours after the inoculation.

Resolving Chemical Gradients Around Seagrass Roots—A Review of Available Methods

Steep geochemical gradients surround roots and rhizomes of seagrass and protect the plants against the harsh conditions in anoxic sediment, while enabling nutrient uptake. Imbalance of these

The seagrass root microbiome: Micro-scale solutions for macro-scale resolutions

While light availability plays a critical role in seagrass growth and distribution, there is limited understanding of how changes in light exposure impact belowground processes. We investigated the

Oxygen dynamics in the rhizosphere of Zostera marina: A two‐dimensional planar optode study

The oxygen dynamics in the rhizosphere of Zostera marina was studied by use of planar optodes and oxic sediment volume around the roots increased linearly with irradiance in the interval of 0‐250 mmol photons m 22.

Contrasting oxygen dynamics in the freshwater isoetid Lobelia dortmanna and the marine seagrass Zostera marina.

It was found that intra-plant transport of O2 between leaf and root tips takes place more readily in L. dortmanna than in Z. marina due to shorter distances and greater cross-sections of the aerenchyma, and this appears to represent a general difference between the isoetid species mainly inhabiting sediments of low reducing capacity of oligotrophic lakes and the elodeid freshwater species and marine seagrasses.

Eelgrass (Zostera marina) tolerance to anoxia

The nitrogen supply to intertidal eelgrass (Zostera marina)

At least during flood tide, the leaves play the major role in nitrogen uptake in this intertidal population of eelgrass: influx of porewater ammonium into the tide-pool water may enable the leaves to exploit local sediment resources.

Vulnerability of Zostera marina seedlings to physical stress

It is hypothesized that the survival of eelgrass seedlings, and thus recolonization through reproductive dispersal, is nega- tively affected by physical disturbances, and the 3 most likely physical mechanisms involved are uproot- ing or burial through drifting macroalgae, Arenicola marina sediment reworking and current-driven sediment resuspension.

Oxygen dynamics in the rhizosphere of Cymodocea rotundata

The continuous oxygen supply may ensure a persistent oxic environment for belowground tissues of C. rotundata and, hence, protect the plant from reduced phytotoxins.
